First thing you want to check is under the carpet where you right foot would rest on the floor. Youll probably find a group of wires that has corroded apart, believe they where orange or red.

would buying the aftermarket repair books help because this is the second day i had this car and also i have a few other problems and wanted to know if a scanner tool will detect these problems

Scanner tool is only usefull really for driveability concerns, ie check engine lights and such. Repair manuals are always useful but If you are a serious do-it-yourselfer buy the GM manuals. They may be more expensive but have alot more usefull info them the other's. Try HelmInc.com for factory manuals.

yea ill most likely get me those books because i got a few problems that i want to get rid off. brake light is stays on in the dash board, rear windshield wiper does not move but makes motor sound, hazard lights wont press down, side mirrors do not move with the elecric control panel and driver seat will not move back foward or up & down. thats pretty much it for now thanks for the help

I have this problem with wires leading to the power seats corroding. There are three orange wires that have corroded severely. How can I tell which ends go to together because they are all orange, or does it not matter?

I have a 2000 LT power everything..on my wires there is one thick orange wire and two thin ones fix the thick one. that will fix the seat.

Isn't there a fuse for the seats?

I have a 1995 Blazer LT with the exact same problems. My power drivers seat doesnt work at all, The power mirrors dont work at all, and my rear windowwiper arm will buzz, with a little help it will work, but most of the time it will just buzz. All the windows work great though... Have you figured out how to get these power options to work yet? can anyone help?

No, there is not a fuse for the seat (atleast on my 99). The power seat, power windows have two circuit breakers. First check the switch. In order to do so, run a small wire from your battery to your seat. Pull the switch out and take the backing off of it. you will see a orange wire going to the switch. Now take the wire from your battery and hold it against the orange wire at the switch. Operate switch. If your seat moves you know you have a power issue. Theres only two reasons as to why your not getting power. 1. A break in the wire, 2. circuit breaker failure. To check and see if the wire is good unplug the connector under the seat for a minute, now plug it back in. If you can operate the seat your circuit breaker is getting weak and you probably need a new one. If it doesn't move then you have a break in the wire.
The circuit breaker is either located in your fuse panel or under the dash, they put them in two different places depending on the year. They are silver blade looking and almost resemble a large fuse. hope this helps

Thanks man, this may be a stupid question but, how do you get access to the power seat switchs, its like attached to the seat... i dont see how i can get to it without taking the entire seat off? does it just pull out or push in?

Best thing to do is pop the caps on the back and front rails... Use a 15mm box wrench to remove the nuts (even though it doesn't look like it, you will be able to get to the rear nuts...

Once the nuts are removed, pick your seat up and tilt it back... You will see 2 plugs... One is for your lumbar, the other is for your power seats...They are interchangeable as they are on the same circuit... Orange is 12v positive, black is ground...

Disconnect these 2 wires...

Get a multimeter... Check the power to the floor side plugs... Since some of the wire is corroded you may or may not get power... Snip out the corroded portions. Splice in new wiring (color doesn't matter, hard to find orange wire, use 10/12 gauge... Get a spool or red and a spool of black)

Splice these wires into place. You can use butt connectors and a crimper but doing that is unreliable... The best way is to solder them, then cover w/ heat shrink, then tape...

If i remember right, the switch is mounted on the trim panel along side the seat to hide all the motors and what not underneath the seat. Pull on the plastic, i believe it just attaches with clips. I'll try to look at a earlier blazer since mine is a 99, but they should be about the same. Give a pull it should just pop off.

The driver's side molding is actually riveted to the seat frame.... and the controls are snapped into the back of the molding. The passenger side is only held on by clips (unless that is power too)

Thank you, im going to do that today, i'll let you guys know how it works out... i know its not the circuit breaker because the breaker is for the powerseats, and power locks and the power locks still work so its not the breaker...

Also, what about the passenger power lumber? wiring and what not? where do the wires go for that?

Actually the top one is for the seats and locks, the bottom breaker is for power windows.

well, completely removed the Cellular one package from my blazer, while i was at it, i looked over all the seat electrical lines, i pulled the driver carpet up, it was sopping wet, i have no idea what from... but all the wires looked to be intact... any more suggestions?

Are you sure. I know the haynes manuals are not always correct but heres what i found. I'm looking in my haynes manual and the wiring diagram shows me that the power lock has its own circuit breaker, relay and it is fused as well. It does not tell me where the breaker is though.

Power seat shows there is a 20amp circut breaker at the fuse block, thats it.

Power windows have a 30amp circuit breaker at the insturment panel fuse block and thats it. If the book is right i'd try the breaker. Every power option as you can see from what i just gave you, has there own protection devices. Go back to my earlier post and do that, you should be able to figure it out pretty quick. Good luck.

Guys, I’m happy to report that I fixed the Power Seat & Lumbar problem, it was the wires under the carpet, they were wrapped in a protective plastic sleeve, I pulled them out and there was like 20 wires all together, the power seat one has a factory splice for the power and ground they were very corroded, Orange power with one lead, spliced into 3 wires: Driver power seat, power lumbar, and passenger power lumbar. I just spliced the wires and now it works great. SWEET….

About the power mirrors…Anyone have any suggestions as to why they don’t work?

About 2 years ago i was having a problem with the Power accessories/keyless entry not working, including the seat. The Fuse would get ultra hot when it was in. Once the fuse cool down id put it in and get power seats and keyless entry for about 1 minute, than nothing. So i started by checking the power seat (on my 97 only the drivers). Went underneath and pulled the controller out and there it was. A frayed wire was grounding on the seat causing my fuse blow issue. Patched up the wires (GM wanted around $30-50 cant remember for the wiring harness, so i just did a thorough wire repair) and i saved the hair on my head. So if anyone is experience this or any other problem related with a fuse blow out issue, thats a good place start. So this may confirm some of the other peoples fixes.
