Water in floor pans?

I just pulled the carpet, for cleaning (pretty easy), but am seein' copious water in driver's and passenger's floor pans up front (no rust, yet:licka: ). This has gotta' be a plugged AC condensor drain - right:frown:

Where's the drain pan, to unplug???

Could be a heater core? perhaps what year

Could be a heater core? perhaps what year

Is your coolant level okay?

Update...

I got drops of water from the condensor drain when I put my finger to the opening. Not plugged, right???

So I put the shop vac to the opening, just to see if it pulled any thing else - water/condensor jam/air, etc. Nothing. Not even air would pull through.:dunno:

I then stuck an allen wrench into the opening, and could feel nothing in there - no plug; just some water.

Anybody know the design of this pan/box???

Any ideas?


bump...

Okay guys, I got my can opener out, and am gettin' ready to go in.

Does no one have a clue on this???

I just checked the interior filters, just to see what I could find before I went underneath the blower/duct access. The two interior filters are absolutely filled with leaves, acorns, etc., and compost/topsoil.

NOW, I am hopin' that this is why the shop vac would pull no air from the condensor drain hole, when the hole does NOT have an obstruction in it... (see above)

Cross your fingers (and yer little piggies)...


EDIT:
I'm guessin' that if the interior (cabin air) filters are clogged, and air can't pull through THEM, then air will be pulled in from the condensor drain hole, which will in turn, stop water from draining out through the hole:wink:

are u sure the windsheild isnt leaking rain water in? i have seen that on a 02 venture

also it could have a leak at the cabin airfilter

also it could have a leak at the cabin airfilter

Positive.

I thought that (rain leak) as a possibility at first. But I dry out the water each morning, after 10 hours of driving each night, and the water returns.

No rain of late either.

It's from the evaporator, no doubt - just a question of why the juice ain't drainin' out the drain hole...

Okay... Here's what we've got.

I didn't go into the condensor drain access when I found the condition of the interior air filters.

I pulled them, cleaned and dried them. They will hold a lot of jam. While they were drying, I put the shop vac back on the condensor drain hole. Remember, I could feel no obstruction before, but the shop vac still wouldn't pull anything, including air. This time, with the filters out and drying, it pulled air. Not as much as I thought tho', but I didn't know what to expect, if anything at all.

Now the filters are back in, and air is moving through them (I smell the soap:bloated:). It will take a while to see if the water can now drain out the drain hole.

This will answer the question from post #5 (EDIT), about pulling air IN, through the drain hole, with clogged interior air filters...

We are awaiting the outcome so.
So let us know if that helps.
But a stopped up filter will not keep it from draining if the drain is open.
To clean the drain give it a good shot of compressed air and ge out of the road because you may get a wet bath.:grinyes: :lol: :rofl:

My drain was open.

It would NOT drain.

If you have a suggestion about what to look for, I welcome it.

As said in other post.
There is no way a blower can put a suction on the drain outlets or vents.
The drain is on the air out let side of evaporator and evaporator outlet air vents.
Put you finger over the drain vent and see what you feel.
If you do not feel air coming out your drain is stopped up.

I still think you're wrong on this.

For one, it's the only explanation for what I had going on. Read the steps and conditions carefully, that I went through...

For another, I read in another 'water sloshing' thread, that if the control is set on re-circ, as opposed to fresh, the problem of water went away. Or vice versa. This also would explain how suction might be applied, which could in turn, allow water to not go out. (I'll see if I can find that one again, to confirm).


If I can, I'll try to re-create the problem, and see for myself, with both settings...

Sorry but.
Your theory does not hold water. :grinyes: :rofl: :rofl: :lol:
Go talk to the air cond people at .

And see what they have to say about it.

We got water still.

The lower console is out. 20 sections, about 40 gigascrews.:bloated:

I got a plastic panel loose below the condensor (gotta' pull another 20 pieces to get the panel completely out:shakehead), and expected get some juice when the section opened. Nothing:wtf: :wtf: :wtf: I could see the condensor, and everything looked dry. It was driven an hour before, and there's a lot of water down below.

Anybody got any other ideas...?

Sounds like you need.

Is the drain pipe and fliper threw the fire wall open good?
Run something trew it and see if it is open or hit it with some compressed air.
I have saw bugs and everything else stop the drain pipe or fliper up.
Also remove fliper and see if that helps.
If so the drain pan should be draining.
If you can pour a little water in it and see if it drains out under car.
Are you sure it is pure water leaking in floorboard.
If you can just stick drain pan back up with a screw or two run it some and then peak back in drain pan.
Good luck and let us know how it goes.
Also about them death kits here is a couple of links on them.

I don't know how well the pipe is cleared. I stuck the allen wrench in, and angled it around. Felt nothing. The GM guy said to be careful, for the fins of the condensor. Now that I've got a peek at the condensor from inside, I don't see how that was possible - it looks further inside the firewall than that. But I don't want to find out he was right.

It's pure water - not antifreeze, or W/W fluid.

I don't have compressed air. I got a length of marine fuel line to the drain hole, but couldn't get a good seal at the drain opening. Some air I was able to blow through - about as much as the shop vac pulled. I didn't hear any gurgling, or anything.

Not sure what you mean by fliper... A door in the duct?

I'm wondering if the drain pipe is disconnected from the condensor housing, but that hardly likely, since the shop vac at first would pull nothing.

Has no one in this forum gotten into a Chevy Venture condensor housing???

totally diferent car here, but a buddy of mine had the same problem with his Dodge Intrepid. Wet floors after AC was running.

Drain tubes were fine. ended up that while driving the drain tubes were doing their job, however the water would fly back and run slong a seem in the floor pans, resulting in the water woking its way into the car, and soaking the floors.

they sealed the seems underneath, and added and "extension" tube to the drain tube, and the problem went away.

have you ever just let the car run, watch for drips, then back track to the source?

I just got concurrence on this extension tube theory at the site that MT referred me to...

... see 'GM tech's' response.

Will re-post after extension tube install. Cross your fingers, yer piggies yer eyes, yer teeth, cross 'em all!!!!!!!!!!

I am glad to see you got some good info at ackits on it.
Them people know there stuff.
And I think Bleepster hit it on the head to.
And it may boil down to that flipper you asked about.
There usually is a rubber flipper valve on the end of drain pipe.
Could be your problem.
Good Luck and let us know how it goes.

THERE IS JOY!

And there is no water!!!

The elbow has made all the difference. I could find no OEM part; a GM backordered part (my company distributes GM parts to GM dealers overnight shipping in half my state).

I found in a generic retailer a 'HELP' part - a PCV filter elbow for a Chrysler, pt.# 47028, and snugged it on, with no extension.

No water all the night.


You got good info bleepster, good referral MT!

Thanks for posting back how it went.
Glad you got the problem fixed.
And Yes them people at ACkits know there stuff.
