It was raining last night and this morning, I don't remember seeing it this morning when I left home but I also didn't even look down there (never had a problem with rain before.) Out running errands, park in a parking garage. Still in the garage I try the pedal trick to reset a CEL. Takes me forever I can't get it to clear. It gets hot inside the car, at this point I run the AC on and off for periods of time while continuing to try the pedal trick for my CEL. I lift the hood covered in sitting water, to check a few connectors. Return to the car, try the trick more and finally reset my CEL. Now I leave the garage and while sitting at a red light I'm looking around and notice water on my passenger rubber mat. Dried everything the best I could and returned home. Left it out in the rain and came back out 15 minutes later with no water. Sat in the car with AC on full blast on and off and no water..

So, its raining more than usual and I have a leak? I raised the hood and caused water to run into the car instead of it's drains? Playing with the AC how I did caused the compressor to leak inside the car? A friend installed a new cabin filter a while back, maybe everything isn't buttoned up perfectly?





Feels wet above this plastic piece (under behind glove box)
Carpets are wet all the way to the top, not just next to door sills




Would like to take care of this ASAP, I want to avoid mildew and rust!
Thanks all !

 

AC drain hose may be disconnected or clogged?
You should see the AC condensate dripping from a small drain hose underneath the passenger side of the car

It sounds like from your description that it's from the AC system and not a leak into the car. If you remove the glove box to where you can see everything and run the AC full blast you might be able to sit over on the passenger side and see where it's coming from.

Telcoman may be on point with a blockage in the drain hose. That'd be my guess.

 

Ok thanks for the quick replies!
I'll have to see if I remember how to get the glove box apart and the panels off.

 

There's a DIY on changing the AC cabin filter that shows it step by step somewhere here on the forum.

Awesome guys, I'll give it a try when these storms pass. Hopefully I'll be able to see the problem area. Thanks.

 

Do you have an after market sub and amp installed? Some people that run external sub and amp use the rubber grommet just above there to get the power wire into the car. I have seen some people complain they leak after that as you need to cut a small hole in the grommet to get the wire thru it. In the DYI I followed it stated to seal it with some silicon or similar.

 

I do not have any aftermarket audio installed. But good to know if I ever decide to.

 

Check the cover that goes over the battery. I had removed mine before and had not put it back on. The rain went trough the cabin filter onto the carpet

 

Oh wow, I'll check that out.

Lately I've been running the AC on full blast along with it raining since my original post. I have yet to recreate the problem..

 

Any update on this? I just discovered my passenger side floor was wet as well.

 

Well I'm back. After trying to recreate the problem many times I decided to just let it go. I haven't had the problem since under the same conditions. But all of a sudden today, I have wet carpet again. I am stumped on this one!

 

Did you check your AC drain, it could be clogged. The drain is literally right under the passenger footwell. It's an absolutely horrible design. Mine drains into the railing under the car. Took me about 15 minutes to try to find the drain.

 

I have not checked the AC drain but there was a puddle under the passenger side of the car. Wouldn't this mean it's draining correctly?
