So about 3 days ago i noticed when i was cleaning my car, the passenger floor was wet. I thought i left a window or sunroof open on accident while it was raining the day before. So i just used a leaf blower and dried it off. So today i just decided to check up on it and noticed its wet again and the carpet under it is also wet, its not as wet as it was 3 days ago but its still wet. Anybody know what the problem could be?



edit - Also instead of making a new topic i thought id just ask here also, My A/C only gets cold at random times and whenever im driving fast(like 45+). If im at a stop light or something it just goes back to being cool/warm. Also a while back it started smelling kind of bad (sort of like mold i guess?) but the smell has gone away for now but does anyone know why this is happening?

Also was wondering how much it would cost to get this stuff fixed.

Thanks in advanced

When was the last time you changed out the cabin filter? This could be the cause to the mold smell.

First i would try this. Open you sunroof, look in the front two corners, and look for a hole in each side. Take some compressed are with the straw and stick it down in there a blow the shit out of the inside of the holes. I did this and it worked like a charm! I first noticed this while going through a drive through wash and my friends feet got wet. Try this it might be your problem! Also, I talked to a lexus tech and thats the exact advise he gave me!

Wet floor is almost always the evaporator drain tube being clogged. condensation from you A/C evaporator collects, normally it drains out a tube under your car. Sometimes it gets plugged, by insects, road crap, or a quick lube monkey who is sick of it dripping on him while he changes your oil. Anyrate, ensure this hose is clear, you'll find it on the passenger side of the firewall, near the exhaust manifold, angled down.

go with lextech for the floor, that's typically what's seen.

as for the a/c. could be low on refrigerant/ have a possible leak orrr the compressor is goin out.

take it to the dealership unless you know someone good with lexus'.

Sorry for late response, thanks everyone for the help

Changed it during the summer whenever i first noticed the smell and it didn't go away, its not really strong now(maybe cuz im not really using my ac :\)

Yes my heater still works

If you have the A/C only cold while engine is going fast, you have a Freon level problem.

This could be overfilled or under filled.

My new Sunny had this and it was overfilled.

Get your pressures checked and any leaks fixed, Vac and re-charge and away you go.

I would check the A/C specialists and get a quote, or buy yourself a gauge set, they have come down a lot in price, use the hrs above as an upper limit IMHO

How long have you had the car ? Could it be overcharged ? Any work done on it or have you had someone fill it for you ?

I got my IS about 5-6 months ago. I have no idea if its overcharged(I'm not really car savvy but im learning :\.), the only work i've really done on the car was changing the oil and replacing the air filter, nothing else. I'll probably stop by a dealership whenever i get paid next week and see what they can do about the AC.

I've heard of issues where that drain would get clogged and disconnected. You may want to run some compressed air thrue the pipe to see if it got kinked. If it only happens when the A/C is on, well then you know for sure it is the drain tube. Otherwise, if it happens with the A/C off too, then its probably the heater core.

^^^ what Jason said.

Also check whether its clear water or colored coolant....This will save you some time chasing the wrong thing.

I have a friend with an IS he was haveing issues with wet carpet on passenger floor, we bypassed the heater core and still have moisture. He checked the drain hose and it came loose. I have not looked under the dash yet. How involved is it to get this back together and cleaned out?

It's not too difficult, just alittle cramped in there. Look behind the glove box and simply reconnect the tubing. Here's what the drain line looks like.


This thread has a pdf in Bartkat's post to show how it's layed out.

Problem Fixed!

I just had the same problem. The water was actually dripping directly from the condenser because the entire housing around it got filled with water since the hose (black hose circled in the picture in the previous post) was clogged. It would drip around the cooling fan where the air filter is housed. It took some digging online to find out that that black hose was clogged.

You can find the area circled in red behind the floor mat and carpet. Just pull it down and away from the firewall on the passenger side, upper left behind the glove box.

How I cleared the hose was to use a compressed air can, disconnect the black hose from the translucent hose, and spray the compressed air into the hose. I stuck the tube from the compressed air can into the hose and then sealed the black hose with my thumb. Worked well enough. Some other posts suggest against this method since it might damage the hose but i think a compressed air can might be ok. Also, my thumb was an imperfect seal so if it is really clogged, my thumb would not be able to keep a tight seal on it.

Another method would be to jam a thinner rubber hose down the black hose to see if you can clear the clog. I would not use a wire or anything sharp since that can punch a small hole through the tube.

My carpet was fairly wet with water. Luckily no mold developed since i fixed it a few days after it happened. I slowly dried the carpet with paper towels (really wish i had a sham-wow at that point) and then left it for a day in the sun. Fairly easy fix. Drying the carpet took longer than to find the black hose and clear it out.

It took some driving around with the AC on and parking afterwards to see the water flow through the hose and onto the ground.
