2000 Rodeo, wipers work when on, no intermittent control. They just stop where ever they are if you swtich to intermittent control. I've heard this is a module above the glove box that costs about $200. Is it parts on the board in the module that fail so the module has to be replaced, or can I open the module, resolder grounds etc and restore operation? If not, anywhere less expensive than the dealer to get a replacement module?

www.car-parts.com

find a junked rodeo in your area and pick and pull the part.

Same happened to mine. It is the alarm module located under the glove box on the side wall. It's grey and is located above a smaller black box which I think is the keyless entry reciever. The replacement unit cost a fortune here in Australia so I opened mine and fixed it. It requires a simple $1 relay replacement. If your smart with electronics you can identify the relay by shorting the correct legs to identify the one. There are three large ones from what i can remember. Sorry, didn't document what I did.
I'd be careful using a 2nd hand one as you will probably have the same thing happen again. The original relays are cheap and just wear out i think. Worth a shot. By the way, that anoying buzzer is on this board. You can place some tape over it to muffle the buzz while your there.

Cool! Just what I was hoping to hear. I can handle that, low voltage systems (fire, nurse call, etc) is part of what I do. Don't do trouble shooting down to componenet level on circuit boards, but a relay change out is no sweat. Thanks for the reply!

some are red some are grey

Well I did it. I pulled the module, opened it and pulled out the circuit board. Took a little while to determine which of the relays was the one for the front wipers. Being late on a Saturday, was too late to find an open electronics supply house, so I found a relay at Radio Shack. The coil had a nominal voltage of 9 volts, but the contacts were rated at 12 amps and it was the right size and configuration to solder right to the board. Worked great. Only spent $5 on the relay, and $7 for a solder removal tool. Would only recommend attempting this if you have some experience messing with electronics, circuit boards, volt/ohm meters, and soldering.

A BIG thanks to 2000Frontera in Australia who told me what to do!!

Well done! Sure beats the hell out of paying for a new one. Seems to be a few owners with older models starting to suffer this. Perhaps you could start a little business over there. They mail them to you and for a nominal fee you could repair them.

Regards, Wayne

You know the thought crossed my mind. But I'd have to have some kind of test rig to check them out before and after repairs so I wouldn't have to test each on on my vehicle. Also, don't know what else that board does, would probably end up getting boards with other problems and get caught in the "Well it was working before I sent it to you" trap.

I will be placeing this soon since I have the same problem. I have located a replacment board for 30 bucks, so I will have my old one for parts. I removed the old part tonight. I do not have the factory so there was no black black to move. Also the board was in a brownish colored plastic box instead of the noted gray (I have a 2000).

It took me about 20 minutes to pull it out and then put it back in. I'm sure, now I know what I'm doing, I can do it in under 10 minutes. Hope the used part works. If not, well then I can practice my soldering skills on the used part and not worry if I mess it up.

I've got intermittent wipers again.

Thanks for the good work men. With out you guys sharing this information I would have been out ~$250 (USD)

I got my relays from Mouser last Wednesday and installed one last night. Eureka it worked! The relay cost $5.10 (USD).

I had to call the US Fujitsu distributor and ask them to sell 4 relays to Mouser to resale to me. It took three weeks to get that finalized. Besides that, getting the relay off the circuit board was the biggest chore for this fix. Well worth the trouble.

Now that you have the supply chain set up, I'd gladly buy a few of these relays from you if you could get more (marked up for your trouble of course!).

I don't have an agreement with Mouser to buy quantities less than 125.

What I did have was an agreement with Fujitsu to sell Mouser 4 relays to re-sale to me. Its my understanding that Mouser can only buy and sell lots of 125 from Fujitsu. Mouser doesn't stock this part.

I can only hope that if enough people contacted Mouser wanting to buy these relays they might stock and sell quantities of one zees and two zees.

I've sent an email to mouser with a request to by 10 more. If I can buy ten I'll sell those.

Update 08 Dec 04
Mouser responded, "We have 0 stock on this part and our minimum order requirement is 125 pieces. You will have to get approval from Fujitsu to order a lesser amount."

Does anyone want to organize a group buy? I've never done it. Not sure how it works.

Is the rear wiper also controlled by this circuit board?

I am having no problems out of the front set of wipers, but the rear will work once out of 50 times I turn on the switch.

If it is controlled off of this board which relay is it?

Provided your truck has a similar A&C unit, the upper left relay marked P1NO12N is the rear wiper (see the above picture). In the picture the front wiper relay is circled.

Here's a link (http://www.automotiveforums.com/vbulletin/showthread.php?t=243753) to a thread where KJK swapped the relays and fixed his front. His rear stopped working.

Good luck.

Thanks for the reply. I got my board out today and looked at the different relays. Now that I know which one needs changed....

....where are you guys buying the relays?

Thanks, again.

Actually, the relay to the left of the circled one in the picture is the rear wiper delay. When I "fixed" my front wiper delay problem I couldn't find a proper relay so I just swapped the position of those two relays because I never used the rear wiper.

will any 12volt relay work on this provided leads can be added to match up with the holes? The reason I ask is I work commercial access control (card access) and have "ice cube" type relays laying around everywhere. I'd like to just use on of those. Is there anything special about the relays mentioned above other than the foot print being the same?

98 Passport - Front intermittents and rear wipers do not work. Reading this thread I just ordered the relays from Mouser (they ARE available now in qty's of 1 @ 5.10 each). I'm hopeful this will solve the problem. I priced the Alarm Control Unit from Honda locally and it is orderable at $208.00. If I can fix this for $10 I'll be a happy camper. Thanks to all who post on this thread for the info and pics.

Thank You Very Much!!! You guys have been a lifesaver, or should I say money saver. This is the best board ever!!!

I have two Isuzu Rodeos, a 2000 and a 2001. I too had the same problem with the wiper failure first with the rear wiper in January and then about a month ago with the front wipers on the 2000 Rodeo. I verified that the problem was NOT with the wiper motor and didn't know what to do next, so I searched the web and luckily found your postings!! :) I contacted ISUZU to see if they had a recall on this board problem because it clearly is pervasive on ISUZUs. Unfortunately there is no recall.
So I followed your instructions and obtained 4 relays from Mouser because I fully expect my 2001 Rodeo to have this issue sooner or later! I received them this weekend and successfully installed two relays on the 2000 Rodeo with wiper problems. This solved my wiper problems on both the front and rear. Let me add that I am NO auto repair expert, rather someone along the lines of a shady tree mechanic trying to keep cars on the road without huge shop bills.
I thank all of you very much for your well documented postings and the photo of the board!!!
I'd like to add one more hint on replacing the relays.... I utilized Radio Shack Desoldering Braid Catalog no. 64-2090B to remove the solder holding the old relays onto the board. This braid acts like a vacuum absorbing the solder so it doesn't mess up other board components.

What about a '99 Rodeo that has Omron relays on the alarm control board? Does the same thing apply as far as being able to but a single replacement relay and soldering it into the circuit board? I have pulled the ACB out and see 3 relays similar to what was described earlier on this thread. Any one ever run into Omron G8QN-01 relays and know of a place to buy one.

Also, if I'm able to get a good price on the whole replacement board, is the connector to the board soldered to the board? My connector is green plastic and looks to have 2 pins that stick into the connector and when you turn the board over, it looks like the other end of the pins are a large soldered connection.

Any help is appreciated.

I keep reading again but I may be missing something. Is the relay only for the intermittent setting or for overall operation. I'm asking because my front wipers stopped working yesterday in the middle of a downpour (of course). They just stopped in mid-stroke. When I try to turn them on they don't move but I can hear what sounds like the motor working. Also the fuse is fine.
Any response is appreciated.

Hi all! I'm new to this forum, but you guys have saved me time and money. I had same issues of front and rear wiper stopping or not working at all. I bought three new relays from mouser and got the front wipers and intermittent delay working, The rear however refuses to go further than a few inches. Does anybody know which relay controls the rear wiper and their intermittent control? Does anybody have a picture or listing layout of the alarm control unit so someone like me can easily identify locations and what each item does?

Thanks again for the time and money saved so far.

Gentlemen,

I have a '96. I've tried to use the instructions here to find me rear wiper problem. The description of where the relay box is located does not match what I see in my truck. Any pics or help please.

The picture is on the first page of this thread. The circled relay in the picture is the front wiper delay. The relay immediately to the left of it (on the same row) is the rear wiper delay.

I had problems with the front wipers on my 2000 rodeo ls, and just completed the replacement of the front wiper relay (ordered from Mouser) as discussed in this thread. It worked perfectly! So I wanted to share specifics of my experience in case they may help others to identify and fix their problems.

Standard disclaimer -- USE AT YOUR OWN RISK.

First, here are the exact symptoms that I saw:
- when the wipers were parked (at the low resting postition), turning them to intermittent would bring them up about a third of the way, and then they would stop and not move again unless I switched to low or high speed.
- low and high speeds worked fine, except that if I turned the wipers from low or high to off or intermittent, they would simply stop at whatever position they were at. Only way to get them to the parked position was to turn them off at the perfect spot in the arc.

I read on this forum that it was probably the alarm control unit that was causing this problem, but I wanted to be sure so I got the wiring diagram for the front wiper system. This showed me that there are basically three components to the system:
1. the selector wand (multi-position switch) on the steering wheel. This actually consists of two switches and a variable resistor or some such for the intermittent interval.
2. the alarm control unit
3. the windshield wiper motor assembly, which basically includes the motor plus a switch that detects whether the wipers are parked. (at the low resting position)

I concluded that the windshield wiper system basically has 2 modes -- "run" and "park". When turned to low or high speed, the system is forced into "run" mode, and everything works fine. But for intermittent operation, and to get the wipers back to the parked position when the wipers are turned off in mid stroke, the "park" mode is heavily used. (more specifically, intermittent is basically the computer jolting the wipers out of the parked position, and then letting park mode take over to let them return to the parked position.)

It seemed like the park mode was basically broken.

With the battery disconnected and the computer disconnected (because I didn't want to accidentally fry it with the current from the continuity tester), I tested the three switches in the system using the continuity tester. They were fine, so I concluded that the computer was probably at fault. So I decided to try replacing the relay.

Next up... putting in the relay. First I had to get the computer (a.k.a. alarm control module) out. Based on advice from this forum, I removed the glove box using the two screws underneath, disconnected the wires from the alarm control module (ACM) then found the screw directly under the ACM (hidden by some wires) and removed it. This allowed me to remove the ACM without removing the box below it. With the ACM out, opening it up was easy -- the black face on the connector side is removed by unclipping the 3 clips holding it in place, and then the board slid out of the box.

Based on the picture shown in the thread, I went about removing the front wiper relay. This was definitely the hard part, as I'm not an expert solderer. (or de-solderer) I had purchased some de-soldering braid for radio shack, and found it tricky to use, but eventually got the hang of it. Specifically, I had to find the 5 soldered pins on the back of the circuit board that corresponded to the 5 pins on the relay, and carefully remove the solder for each one. I tried placing the braid on top of the pin and punching the pin through the braid, then heating the braid, but this didn't really work. In the end the best way to do it was to push the braid up against the side of the pin, hold the soldering iron against the braid, and wait for the solder to flow into the braid.

Even with the solder "removed" from all 5 pins, I still had some trouble working the relay out, but I did so very slowly and it eventually came out.

Putting the new one in was a little easier. I use a pointy object (small safety pin end) to clean out the holes a bit, and slowly worked the new relay into the hole pattern. Soldering was easy... just held the iron against one side of each pin, and touched some solder to the other side of the pin.

After that I put it all together and it worked!

Thanks to all on this thread for the great info. Saved me somewhere between 200 and 350 bucks!

I just called Mouser, and they no longer stock this item in singles. Does anyone have another source for these relays. Alternately, if I bite the bullet and order 175 of them, would anyone pay $10.00 (including shipping) if I wanted to sell them?

Thanks,

Mark

there is another relay that you can use. I believe the part number is in the FAQ's. If I remember correctly, it is made by NEC.

marc

I'm glad I bought my relay when they were still selling singles.

I didn't notice the substitute relay mentioned in the FAQ section. I'll do a little research and see if I can come up with it. If so, I'll post it here.

Thanks,

cool, I am most positive they are correct. I ordered one of each back in November and the NEC lined up perfect. I put in the other since it was the OEM. I am pretty sure many others have used the NEC though.

It had been years since I last soldered and I managed to get it. It takes patience though. Good luck with it, it isn't too hard though.

1999 Rodeo LS 3.2 V6 4x2

www.car-parts.com (http://www.car-parts.com)

find a junked rodeo in your area and pick and pull the part.

Have found the needed ALARM MODULE at a "junk yard" with the same part number as I was given at the dealership Parts Dept. for a NEW one. However, the junk part is off a '99 Honda Passport - NOT an Isuzu Rodeo. Inasmuch as Isuzu manufactures the Passport for Honda, and they are IDENTICAL (except for the Honda insignia), may I presume that this part will work in both vehicles.

I ask because when I called the dealer parts dept. I was asked which MONTH in 1999 was the vehicle manufactured, as there are THREE different circuit boards on the '99 modules!!!!!!

ALSO... there's a good chance that this part off a junk vehicle DOES NOT WORK any better than the one on my vehicle. The salvage place cannot verify that the circuits and relays are in "working condition". If this part does NOT resolve my intermittent wiper (and rear wiper) problems can I insist that they take it back? They said they only "exchange", but very unlikely that they have very many of these particular circuit boards.

Thanks for any input here.

Two days back i replaced rear wiper relay RY3, it worked fine but today wipers have stopped working again. When i press the rear wiper switch i can hear relay tick but no action on wipers. Are their any other relays which need to be replaced? I used nec 3100 and my alram box is red.
rodeo 99 v6

Artchee, There is no way to make sure the used alarm module will work unless they will let you plug it in in the parking lot before purchasing it. Even then it may go out as soon as you leave the place. Those are the chances you take buying used parts. I don't know anything about the 3 different boards depending in what month your truck was made, but they all probably do the same thing just in different routings. I would ask to size it up at the yard. You can drive your rodeo with everything already disassembled and then all you have to do is pull your box out when you get there and plug theirs in. If it works, great. If not, then the soldering to replace your own relays is really simple. Anyone can do it. All it takes is 2 screws in the bottom of the glove box to remove it and then you can easily get to your alarm box. There are a few good listing in this post on how to do it.
Hope this helps.

1999 Rodeo LS 3.2 4X2

Did you recheck the plug connections on the box? If the plug isn't seated correctly you can have inconsistant contact with the leads and the wipers won't work all the time. When I fixed mine, I thought I had done something wrong because the wipers would reset back to the start position, but the intermitten setting wasn't working. After pulling it apart and rechecking all my solder connection I realized the plug wasn't seating correctly even though it looked like it was good to go. Once I got that squared away, I haven't had any problems. I used the NEC 22111 relays, but I guess the 3100 are even closer to specs then the 22111. I also replaced all 3 relays at one time.

1999 Rodeo LS 3.2 4X2

Rodeo4me,

I agree with Chapy, check your conection and solder joints first.

There are 2 relays which control the rear wiper with my box. I'm not sure exactly what the second one does but grounding the common pin for the contacts opereated the rear wiper. Check http://forum.planetisuzoo.com/viewtopic.php?t=5608 for what my board looks like and which relays did what. I always suggest to replace all 3 at the same time, the relays are cheap enough and you only have to do once that way.

Artchee,

Its probably alot cheaper and easier to just buy the relays and replace them. I've never heard of different boxes in the same year. I know different years have different boxes (mine was actually build Oct. 98). Others who have never soldered before have successfully replaced the relays in theirs, its not very difficult. Just do a web search on how to solder, or find someon e you know to help. The relays are less the $2 each from Mouser (http://www.mouser.com/?Ne=300&handler=data.listcategory&Ntt=*nec*%2b*31000*&terms=nec+31000&crc=false&N=380&Ns=SField)

Check the link I posted above to planetisuzoo for the writeup I did on replacing mine.

I am about as bad of a solderer as there is and I did it. It doesn't look pretty, but it works great. It tooik me a while to do it, but I got it done. Even for a novice, this is a simple job. Just a bit time consuming.

Guys,

I have a 98 Rodeo and I am having the wierd wiper problem, but I dont have the intermitent wiper or alarm on my truck. I just have the 3 speed wipers and they just stop in the middle of the cyle. Sometimes when you turn it on high they start again. Do I have a simmillar circut board and if I can get the part does it just plug in?

I am kind of new here and would appreciate some help.

Thanks,

Rob

Yours probably has the same box, just a relay or two might not be used.

If you buy the whole box it will just plug in. If you just replace the relays the old ones will have to be unsoldered and the new ones soldered in. Others with no soldering experience at all have successfully done it.

Gizmo42,

This thread is kind of old. Is there anywhere I can still get the box or relays. I have soldering experience but the thought of lying on my back and solder getting in my eyes.........

Click on the link it should take you right to the relays.

The whole board from the dealer is around $200 so I would try the relays first. You can just pull it out and work on it where ever you want. Its just a module, easy to remove.

Friends,

I went out to try to find the board you guys are talking about. I took the door off the glove box and to the left is the radio etc, to the middle it is all HVAC, I started to take the thing above that I thought said alarm off oops air bag, :-P, to the right I see something almost impossible to get to. Is that it? I cant seem to post the pics!

Thanks,

Rob Garven

It is off to the right. I think there are two boxes, you want the one further up. Not as hard to get as it looks. When I put mine back in, I didn't even attach it correctly. that was a pain. I just stuck it up there. You just have to look at it and study how it is supposed to come out. Not that bad of a job.


marc

Friends,

Well I did it. On my 98 there is only one box in there and my board is simillar to your pics but different. I had bought a cold heat thing and tried to use it , that thing is junk, I think I melted it inside. Anyway got out the old soldering iron and had a hard time getting the thing out but it finally came. The nec 31000S legs were a l:screwy: ittle different but I got them in and soldered it. It did not look pretty and I kind of made a small mess of the board. I put it back and thought it would explode but everything seemed to work. It was even a little louder which made me feel like I did it right.

I have a few questions. When I de-soldered and soldered it a little solder ened up touching some of the other contacts. I cleaned it up as much as I could. Are the connections on the inside of the board like a sandwich? If I did get some on the wrong spots how long would I know if something is screwed up. Everything seemed to work. Would I blow a fuse or would my rodeo just explode into flames? :-)

Well anyway thnaks for all the info. I hope I did it right!!!

Rob

I too tried the cold heat. I thought it was junk. I went back to a normal unit. Mine was a bit messy as well and I had the same thoughts as you. Mine still works fine though. Keep an eye on it and see if you smell anything odd when in use. I would assume it would short out if not done right. Feels good to DIY.

Freinds,

I replaced my front wiper relay on Saturday and the car ran fine, I drove it 4 times about 25 miles, total . I got up this morining to go to work and almost instantly the car started shifting hard, clunk every time it changed gears (automatic) and when I went to stop the car it slid two or three times about 2 feet from about 30 mph at a regular stop, like there was something wrong with the ABS. When I went to lunch and came home the car was running just fine. All the lights came on and off at start and had no warning lights light up

1. The board I worked on, does that have any control over the ABS and or automatic shifting?

2. I disconnected my battery when I changed the relay, could this have caused the computer to reboot so to say.

3. That damn alarm box is not the cars ECU is it??

Not sure whether i should bite the bone and by the circiut board or wait and see.
It was extremely hot today and yesterday but I have never had any problems like this before, the only thing I did was work on the board and disconnet the battery at ground?????

Rob:banghead:

what kinda of codes are you getting?

I dont have a code reader and would not know where to plug it in. Can you give some advice on where to get one etc. I know I sound stupid but I have an Italian car and I have great results working on it but it is from the 70's and there are no electronics, every time I touch my Rodeo I am in trouble. I thought after the, I thought was successful repair, on Saturday I was getting some confidence. No this. I am going to Yosemite next moth so I need to get this sorted out.

Thanks,

Rob

I have been wanting to fix this problem in my '99 Rodeo for a long time. (My Rodeo was built in September 1998) I finally ordered two relays from MOUSER ELECTRONICS, Part #551-EQ1-22111S. When I got the parts and compared them to the relays on the circuit board they are slightly bigger and the pins don't exactly line up. Since my Rodeo was made early for its year model, is it possible that it has a different circuit board than later Rodeos from the 1999 model? If your circuit board looks like this and you have successfully replaced the relays please provide the part # and seller.

Also, if you have dealt with this circuit board and can point out exactly which relay is the one for the intermittent wipers that would be helpful too, thanks.

I have posted photo of everything I have related to this issue:

I missed this post, but I think you answered my question regarding is it possible for the 1999 Rodeo to have different circuit boards in them.

Thanks


Have found the needed ALARM MODULE at a "junk yard" with the same part number as I was given at the dealership Parts Dept. for a NEW one. However, the junk part is off a '99 Honda Passport - NOT an Isuzu Rodeo. Inasmuch as Isuzu manufactures the Passport for Honda, and they are IDENTICAL (except for the Honda insignia), may I presume that this part will work in both vehicles.

I ask because when I called the dealer parts dept. I was asked which MONTH in 1999 was the vehicle manufactured, as there are THREE different circuit boards on the '99 modules!!!!!!

ALSO... there's a good chance that this part off a junk vehicle DOES NOT WORK any better than the one on my vehicle. The salvage place cannot verify that the circuits and relays are in "working condition". If this part does NOT resolve my intermittent wiper (and rear wiper) problems can I insist that they take it back? They said they only "exchange", but very unlikely that they have very many of these particular circuit boards.

Thanks for any input here.

Are you sure that is the 'alarm and relay' box and not the 'anti theft and keyless entry' box?

Should have more relays in it and a peizo speaker.

My rodeo was built october '98 if you look at the first post at http://forum.planetisuzoo.com/viewtopic.php?t=5608 that is my box.

I'm not certain of the distinction you're making but the box this board came out of is labeled "DENSO ANTI THEFT & KEYLESS ENTRY"

Are you saying there's another box in there somewhere? If you are I certainly didn't see it.

My alarm box was bolted to the passenget side bulkhead up underneath where the vent is located. It had one screw and once that was removed it had a clip that when pushed up just came out even though it was a little different from the earlier pics it was very simillar. The glove box had to come out also. I have a 98 but no alarm, windows, cruise etc. My problems " brake & auto shifting" seemed to only happen once now it is back to normal, I think it was due to the unhooking of the battery nt to my crude soldering techniques!!

That is the wrong box for the wiper relays. There should be another box mounted verticaly right above the anti theft box (which should have been mounted horizontily) labeled "alarm". Its the one labeled alarm that you want, it has the wiper relays in it. The buzzer that tells you your lights are on or keys in the ignition with the door open is what they consider the alarm.

Gizmo, please take a look at this photo and confirm that the box you are speaking of is the "red" box, correct?

I thinks thats it mine was black thogh the one screw held it in and it pushed up around an ince and came out!

Rob

Yep it should be the red one (mine is white). It should have the word "alarm" on it. It may be possible that someone switched their places at some time so make sure you get the one labeled alarm. Looks to be it though with the white plug.

Thanks

:rofl: Happy to report that I finally got the opportunity to complete this project, and it was a success!

Thanks for everyone's help.

Congrats! :smokin:

Knew you could do it, just takes some patience. I prefer to use solder wick instead of a solder sucker, it works better for removing all the solder.

It's unfortunate that i found my way back to this post... i will tell you all right now (in case you haven't figured it out) that if you're having problems with the front wipers, you might as well go ahead and replace the rear relays as well. That's why i am back- i fixed the problem with my front wipers (thanks to the great information here on this post) and then a year later, my rear wipers are in a stuck position.

It's sucks that Isuzu used such crappy parts and we all end up having to buy replacement relays. I'll probably never buy another car from them again (it's the little things that makes the difference, you know?).

Oh well, time to open up the glove compartment again...

Thats why I replaced all 3 at the same time. They're cheap enough its not a big deal to do all of them. I know I wont need to go back into mine again now for quite a while if ever. Still beats buying a whole new box.

Recently changed all three on mine too.

....

i haven't had to replace a relay yet; 1992 isuzu trooper. parts go. 7 years, that's not bad; the hassle was you didn't really know how to diagnose it. now you do. be proud.:smokin:

I'll probably never buy another car from them again (it's the little things that makes the difference, you know?).
yeah, like not having any dealers. . .:wink:

Has anyone found a place to buy the fujitsu quiet relays yet? or a way to to quiet down the NEC ones?

my wipers have had this problem for over a year now and the wifes tired of it.

You can get the fujitsu ones if you want to buy 1000 of them :screwy:

From what others have said the other ones arent all that loud once its in place behind the dash. You can try wrapping some rubber tape around them before soldering into place, should help quite them down a bit. The original fujitsus are actually a smaller relay wrapped in rubber tape then stuffed into the larger case.

Hi All,

I'm new here but have been following this thread with considerable interest because my 1999 Rodeo has the same intermittent wiper problems. The front and rear work pretty much how and when they please. To fix this I ordered three of the NEC EQ1-31000S relays from Mouser and installed them in my board. Now the fronts work great, but the rear doesn't work at all. When I push the button, the relay clicks but the wiper doesn't move. I even swapped the RY3 and RY4 to see if that had any affect. Nothing. Both wiring connectors are solidly connected to the board and I even tried wiggling the connectors. Nothing. Does anyone have any ideas? This thing is driving me crazy.

Someone plz answer this Im having the same problem with mine. I'm about ready to sell this car and just start riding a bike to work. I hate waiting for the rear windshield to defrost.

With a new relay installed it can only be a few things that I can think of.

1. bad solder joint on the relay (can happen to anyone)
2. broken wire. most likely where the wiring goes into the tail gate.
3. switch for the tailgate that turns on the interior lights not working properly
4. bad wiper motor.

I have a 1999 Amigo that has been having wiper problems both front and rear. I found a fujitsu distributor that will sell the relays (FTR-P1CN012N) in quantities of 25 or more. If I was to order 25 of them would anybody be interested in purchasing the ones I don't use for $10 each plus shipping? Let me know and if enough people are interested I will get them on order.

Also, here is a picture of my circuit board. It came out of a green box and has a slightly different arrangement than the others that have been pictured in this topic. Can anyone help me identify what each realy controls? Thanks for the help!

Can anyone help me identify what each realy controls? Thanks for the help! The horizontal one on the lower right just above the connector socket controls intermittent on front wipers. I didn't replace the others, but my guess is the one just to the left controls the rear wiper, upper left relay is washer pump & upper right is horn relay. But be advised I'm only guessing on those last 3 since the only one I replaced was front wiper inter. control relay! The board out of an '01 Passport looks just like that!

If you'd asked 6 months ago, I'd have joined you. Unfortunately, I've long since purchased an NEC relay (551-EQ1-31000S) for $2 or so from Mouser & fixed my intermittent front wiper problem. It is quite a bit noiser than the OEM relay. It bugs the Boss (wife) when she's sitting at a light, but you can't hear it at road speed. I ended up wrapping the entire alarm box in foam & that nearly eliminated the clicking. Whatta pain.

Thank you all for this thread -- I'm stuck with the same "front wipers won't park" issue on my 1998 Honda Passport and I've grown tired of trying to time it right and stop them in the right place.

After reading through all of the posts, I'm still not sure where to find the circuit board to remove/replace the relay that folks have ordered from mouser.com.

I looked to the right of the inside of the glove box and I see the ABS box (which I'm staying away from). I took off the small side panel under the glove box and found a small black box (relay?) at the bottom, then a small white box above it. I unplugged the male/female of this box and my wipers stopped moving altogether, so I think that's it. But then I don't see where this circuit board is that people have posted a picture of. Is it inside part of this white box? Are the parts folks have order from mouser tiny, like 1/8 of an inch?

I've posted a picture of the white box -- can anyone tell me if that's right or if I should be elsewhere?

Forgive my ignorance here - this is my first time cracking open an auto! Thanks...

http://www.strobelsite.com/SharedFiles/PassportWipers.JPG

Its not behind the kick panel its behind the dash. Take the glove box door off, look to the right and slightly up behind the dash. You should see boxes that look like this pic from rodeovyn..
http://files.automotiveforums.com/gallery/watermark.php?file=/500/380286I3010331b-med.jpg

The black one with green plug in the pic that sits horizontally is the anti theft and keyless entry box, the red one with white plug above it (top right of pic) mounted vertically is the one you want. Its labled "alarm and relay". They are different colors so yours might not be red. The board slides out of the plastic box once you get the box out.

Its a little more difficult then it looks but just need to remove the 1 screw under it then slide the box up and it will come out.

Thanks for leading me away from the boxes in the kick panel!

Mine doesn't seem to look like that picture, though. There's a white box with Isuzu ABS on it, possibly the two relays are inside there? I was hoping that I'd take off the glove box again and see that exact look, but no luck. I don't have keyless entry/anti-theft in my Passport, maybe they lay it all out differently for vehicles without those features.

I'm close to giving in and hitting up a repair shop, but I don't want to fail at this!

LG, yes, it's the white box. Remove it (pain in the a**), open it, and you will see the ciruit board.

Thanks again, all. I removed the "Alarm Control Unit" and have two relays on the way in the mail to replace my intermittant front wipers. Exciting times...

The whole Alarm Control Unit (part 8-97124-978-1, btw) runs $233, by the way. So replacing the one relay in there is just a little cheaper! I priced it out in case I ruin the board trying to solder better than my 4-H electric light board from 25 years ago. The pressure is on to do it right...

Where did you order the relays from? My rear wipers have stopped working now :(

I "met" a guy that had done this same thing by finding him on a Google search for the intermittant wiper problem (same way I found this board) and he had two extra. Assuming I don't ruin one I'll have an extra I can mail your way...I think I'll be doing the soldering early next week (he was mailing them yesterday). I'll let ya know...

My wipers are resting nicely in their "down" position for the first time in about 3 years. It worked - thanks to everyone for their help in getting me through my first electrical automotive fix since installing an Alpine stereo and speakers in my old Malibu.

If you're reading this thread and thinking "maybe I should just drop the $233 and buy the whole thing from Honda/Isuzu", don't do it. I spent $11 on a desoldering iron and got some free relays from a guy that had leftovers and I'm a novice with electrical experience from 4-H about 20 years ago.

Did you use all your relays? If not I'd pay ya for one.

Tom.

Another satisfied customer! Thanks to all for the AWESOME information!

Thanks for all of the info, just swapped out my relays and reinstalled. FYI I got my relays from mouser from this link: http://www.mouser.com/search/ProductDetail.aspx?R=EQ1-31000Svirtualkey55100000virtualkey551-EQ1-31000S

they were in stock (assumung you want less than 5000 of them.) I ordered 4@1.68 ea and shipping was around $5 regardless of whether you order 1 or 10. Shipping was quick, and they fit like a glove. A note though, they are louder than factory. I found a solution that quieted them up: I cut several strips of Dynamat (essentially self adhesive tar paper for sound deadening purposes, especially prevalent in car audio). you only need a few square inches of the stuff, and it is typically sold by the square foot, so I went to my local car stereo shop and they were happy to give me a scrap that was laying around. after sticking some onto the relays themselves I lined the plastic box with it too, and the clicking is now unnoticeable.

My front wipers work on the intermittant setting and park themselves for the first time since I owned my '00 Rodeo, but my rear wiper is still unresponsive. I took my box back out and resoldered a spare relay into each position only to have the same result....Any thoughts on where to go next?

Could be a bad fuse, bad motor, or broken wire (most likely where it goes into the tail gate) or bad switch.

You will have to start tracing power and ground through the circuit and see where you lose it. Not a fun task but not too bad.

Glad at least part of it worked out for you though.

ere is my contribution about this problem:

I bought a used Rodeo Isuzu 2002 last year (2006). After one year, Appears the same wiper problem as above mentioned: front wiper do not park in correct position, intermittent not working, has to manually park the wiper by switching them off at the right place. Not life threatening but boring :)

Bringing the car to the mechanics he suggested to replace the wiper switch (come altogether with light switch) which cost $200 for the piece plus labor. I can not afford that and, even if I am far from a mechanics, was pretty sure it has nothing to do with that simple switch. I so decide to review several forum and though at first it was the park switch (or position indicator) next to the wiper motor that was faulty. I was about to open it when I found this thread. I did what you guys recommend and fix the problem for less than $10. Thanks a lot.

However, I found some parts tricky so want to emphasize the thread:

* Alarm box location: remove the glove box by unscrewing the two screws by the glove box hinge. The box is then on the far right side (left steering wheel model) and is about 5 x4x1 inches in size. You don't see the electronic board but the plastic box. It is written alarm on it as well as ABS but ABS just refers to the thermoplastic material (acrylonitril butadiene styrene) and NOT anti-lock braking system! The box is a little bit tricky to pull out (and even more trick to put back in place) since it is hang by a single screw and a hook.

* Solder: the original solder used for connecting the relays melts at higher temperature than usual commercial solder. You need to have a soldering iron that can reach that temperature. Most irons with adjustable temperature can, most fixed temperature irons can not.

* Mouser doesn't sell the original relay by piece; you have to buy 80 of those. Even at $3.60 a piece it is kind of expensive to buy 80 of them (December 2007). So I bought the other relays recommended in this forum: 551-EQ1-31000S which is a little bit noisier (who care) but can be purchased by piece at even a lower price: $1.68. I bought 3 of those to replace all the board relays. Unfortunately the central leg of those relays is larger than the original one and need to be put in place by forcing. Be careful to not brake that leg (I personally bend one but it is still working). Be firm but gentle.

*Putting the alarm box back in place is a nightmare. I spend nearly 20 minutes trying and didn't succeed to put the hook correctly in place. If anyone has some trick please let say it. However, it hold with the screw and don't vibrate.

Last word: I am extremely happy to have fixed that problem myself and am very grateful to this forum and contributors. Thanks a lot. No my wife believes I am a mechanics :)

Sincerely,

It worked for me as well! I have to agree with the above post that it is difficult to both remove and replace the module. I did not replace it back in the same spot in case I ever have to do it again!

I think that Greenwich Electronics sells individual direct replacement relays (part # AR7-012-CQ6S). They have a direct replacement catalog that lists the original Fujitsu relay as the part mentioned here. The replacement is a quiet relay and should not loud click like the NEC many people substitute the Fujitsu with. I'm going to place an order through them and post how they perform/fit.

Here's the replacement guide:
http://www.geirelays.com/acrobat/crossref.pdf

I have problem. My rear wiper works all time when I turn my key. I replaced both dash switches, relays and ....:banghead: no changes-still works. Whats wrong?

Does anyone have any relays left they want to part with? Attempts with Mouser and Fujitsu quotes only offer 80 at a time. Must the border thing or something (Canada). Would prefer the one that fits without too much greif. I am capable, but Murphy follows me everywhere I go.

Hello monkeymantn,
Have you received your Greenwich relays yet and if so are you pleased ?
Thanks to ALL that have posted on this subject as I am very glad to have found this forum. My wipers have not worked for over a year (intermittent and rear).

Skip

I have a 1995 Rodeo and i took out the glove box, but didnt see the boxes that were described. does anyone know where the alarm module is in a 1995?

This message is about +98 Rodeo's.

Relays are available from RS, (Allied Electronics in USA).
RS part no: 627-9151 (Australia), 399-8225 (UK), 821-1038 (USA) cost in Australia is $4.40 inclusive of GST. RS have no minimum order. The relay is OMRON G5LE-1 DC12, and is direct replacement for original (fits without modification & works perfectly). The G5LE-14 DC12 is a fully sealed version and can also be used

Also, glovebox doesn't need to be removed - just squeeze the sides until the stop lugs release from their grooves. The box then drops open fully for easy access to the alarm relay unit.

I wish I'd discovered this thread 3 years ago!

Jules

Thanks for the info. Always good to find more options for replacement. I'm going to post that info in the planetisuzoo write up that I did as well.

As for the glove box, I do it the same way. I just say to remove it cuz its easier then explaining it lol.

2001 Rodeo Sport
Same problem same fix - excellent advice.
I have 2 extra relays from a donor board/module, so email if you need one.

Desoldering the relay is a real pain. I have no real experience with soldering either so that doesn't help. I am using the desoldering braid but relay wont budge. Any tips? Did you just use the braid on one connector at a time and
then pull off the relay. Seems improbable cause some solder kind of always stays. Do you pull on the relay while you desolder? Stuck with desoldering :crying:

I use the braid on all the pins of the relay to get as much solder off as possible. Then while carefully prying up on the relay, put the soldering tip on one pin of the relay at a time to melt anything holding it in place. Just go a little at a time and keep working around in a circle, eventually it will come all the way out. You just dont want to stay on one pin too long and burn the board or pry too much and break it.

That's the ticket - keeping working around :runaround: the relay. I actually worked two posts first to raise it a couple of mm's on one side then worked around in a circle. A solder sucker comes in quite handy .

Well I have done it all. Replaced all three relays on the alarm board and the rear wiper is still not working. :banghead: I just removed it and put + and - from the battery to the terminals on the motor and it doesn't work. I even disassembled the gearing to isolate the motor (incase there was a binding gear or something).
I would assume that since I did this and the motor didn't work, the motor must be fried, yes???
I tried pulling it all apart and checking the brushes etc. Even tried cleaning the brushes and the parts they contact, but to no avail.
When I activate the dash switch it actiones the relay, so I would assume that the switch is fine, too.:runaround:
Thoughts from the studio audience?

OK, rear wiper was not working so I replaced all three relays with no luck... The relay clicks but nothing else. I went to the jaunk yard and picked up another board and now the wiper works but the dome light doesn't. Any ideas?

Thanks

any one? Please...

any one? Please...
I never heard of the dome light being connected with the wipers at all. Are you sure it is not something simple such as the bulb or a fuse?

Its not connected to the wipers but it is controlled within that same alarm circut board. Anyone have a wire diagram of the board?

any one have the diagram for this board?

thanks for the info guys, the dealership wanted over $400 dollars to replace the alarm box. they did tell me that if you just get a new or used device (alarm box) and installed it ,it would crash and would be lost immediatly. I was told that if the module is to be replaced it needs to be hooked up to a tech 2 machine and all of its programing downloaded then that data is uploaded to the new module, because all of the data on the module is your vehicle specific. It contains your vin and other info specific to this one particular vehicle. It seems replacing a faulty relay circumvents data loss or distortion and very cheaply. I just knew their was a few folks around that were smart enough to not get ripped-off by a dealership. thanks for the info guys you saved me $400 bucks.

does any body know what the minimum or maximum amperage is for the intermitent wiper relay i know it's 12 volts but what is the min amps. p.s i can get loads of relays that will fit its just getting the amps right

Okay I have the intermittent wiper problem on a 99 Passport. Intermittent does not work, but low and high do. I ordered replacement relays from mouser, got the old relay off (the one in the picture) put on the new one, buttoned it back up and plugged the board back in. However, now what I get is the wipers working at all settings, even off. Still no intermittent but the wipers do run in low at that setting. What could I have done wrong, messed up the removal/installation of the relay or what? I have unplugged the board for now since the wipers do work in low and high without the board but I certainly can't have them running all the time. Any help appreciated.

Busy Mechanic:
Should be a minimum 20 amps, 30 amps would be better.

rburdette:
You might have gotten some solder between 2 of the pins shorting them together. Mine has devoloped a problem where if I use the rear washer the relay will stick and wiper will keep going until I hit a big enough bump to unstick it. Works fine with just the wiper function though. One of these days I need to figure out which of the 2 rear relays are for washer function and replace it.

I have a 2002 Rodeo Sport that has the rear wiper problem not parking back to it's home after you turn it off. I have read the threads about the relay replacements and at one point I think that Marcus had stated using the NEC 551-EQ1-22111S Relays. But then I see a lot of people using the 31000S Relays. Is there much of a difference between the two cause I ordered the 22111S's from Mouser? Thanks.
:confused:

The 22111s only has a normally open contact and the 31000s has a normally open and a normally closed contact which apparently isnt used. They will both work the same.

Okay, I got the relays from Mouser and removed my Alarm board out of my truck. Mine is brown and it only had two relays to remove. I removed both the front and the rear relays and installed the two new NEC relays. Front wipers still works so at least I know that I didn't screw anything up but the rear wiper blades still wont park back at home after 3 or 4 swipes. It continues wiping for about a minute and then it stops wherever. So I am at a loss now. Any ideas????:eek7:

I tried this repair with the EQ1-22111S relay from Mouser. This looks like it might be a double sided circuit board. I think I might have messed up the top side traces on the board since the wipers don't work at all on intermittent now.

This is actually an improvement since when they were stopping part way up I had to time it just right to get them to park when shutting them off from high or low speed.

I am considering buying a replacement board from St. Charles but I think I have read something about having to 'program' the new board to match the truck. Anybody have any problem replacing this board?

I can understand where the other board (under this one) might need to be programmed since it is the receiver for the remotes and probably has something to do with the anti-theft functions. But the wiper board only seems to control the wipers and the door open/keys in/headlights on buzzer. Can't see where this would have to be programmed.

Anyway, I was hoping someone who has already been here can advise before I drop $200 on this part.

As far as the reprogramming if you replace your board, when I contacted Isuzu about that because the replacement of the chips didn't work, he told me that there was no reprogramming if you order the one that is specifically for your particular rodeo. It is imperative that you give them the correct numbers off of the box so they can get you the right part.

So, Rodeo Intiminator,

You replaced your whole board with the exact one for your truck? How'd that work out for you?

I haven't done it yet. Just priced them from Isuzu and asked them about the programming issue and that's what the technician told me. Your actually getting the whole box, not just the curcuit board. They need the number off of the box, plus the VIN off of your Rodeo to match it up with the correct part. Probably get it next week when I get paid.

this circuit board also controls the U/S light does anyone know wihich relay control it or another way to disable the Up Shift light
