condensation under the rear seat / floorboard

Okay.. so I was wrong.. the front passenger floorboard is soaked too... arrrgghh..

Does that point more towards my condenser leaking or do I still want to check my window/door seal and sunroof?

if it IS my condenser, how do I check for that, where would it be 'running down'? On my firewall or kick panel? I'm worried that this could be unintentional damage from going into my dash to run wiring and mounting my sirius control box for the stereo......

thanks again, ya'll.

I remember reading on clubgp about people having a similar problem. They mentioned clearing out the ac drain on the firewall. I don't know if ours would be similar, but it is worth a shot.

that's some damned good info, thank you very much, 98Riv! I hope that applies similarly to the Riv. I'll start tearing into that and checking it out as soon as the rains pass today.

(sidenote: I understand why the thread was moved, but it took a little time to re-find it. I mod on another board and I pm the original poster if I have to move one of their threads)

Thanks again for all the great info!

Hmm.. the blower is in a different location on the riviera.. I pulled my plastic 'under-hood' cowl a little bit ago and all I could see was body panels (inner/outer firewall), but no drains or anything that looked climate-control/drain tube related...

does anyone else have a suggestion on this one? I'm just trying to figure out where my AC drains now... I want to make sure it's not blocked or unplugged (I was under the passenger side dash doing some of the stereo installation. I mounted my Sirius unit above the plastic trim that drops down with 2 screws (the panel that covers the blower unit and other various electrical devices)..

thanks again ya'll

Does your car have a sunroof? There is also a sunroof drain.

I think it is easiest to find the HVAC drain from the engine side of the firewall - look on the passenger side of the firewall behind and below the power steering pump.

Sounds like maybe a blocked drain - or 97RIVMANN had a problem where the grommet around the drain hose was dry rotted and cracked; might have to replace.

yeah, I have 2 drains that both drain to the front of the car (one in each corner). I guess I should find some heavy wire and 'snake' them to make sure they're clear... but it seems like there would be visible moisture after a rain AND it seems like the "settled water" wouldn't be so 'one-sided'... but I'll check those as well, thanks.

No, there is a third drain. There is one in each fender well and one where I indicated. The fender well drains are rarely blocked because of their size and construction.

I completely overlooked this response when I was typing back.. sorry.. Will go back out and try to find that drain tomorrow.

I noticed lately that under my car I wasn't seeing the water drip from the evap drain and it got me thinking my drain was plugged. After running a sort of round brissle brush through the drain and blowing compressed air through it I think I resolved my problem. After running the a/c I have a nice puddle under the car. Now all I have to do is pull the passenger seat and peel back the carpet to air/dry it out.

Now here is the trick - if you have a garden sprayer you can extend the nozzle into the evap drain hole and spray in some (a cup or so) of the deodorizing/disinfectant solution I described in earlier post, this thread. Did mine last night (the pollen thing). I put car on ramps & went in from underneath.
