Soaking wet passenger front carpeting (2024)

Hi, all...

This past weekend I discovered that the carpeting on the front passenger side was soaking wet....with no obvious cause (no spills, no evidence of a leak). Is there some AC drain on that side I cant see?

Any other ideas?

Thanks

I had the same issue when I bought my 2010 (was a few years old). Yes, the sunroof drain can be causing this, but the problem I had was much easier to fix. Took me a while to find it, and the entire front passenger carpet took a while to dry out and also had some mold to deal with under the carpet. After removing the plastic kick panel by the passenger's feet, I noticed that there is an access panel about 2"x4" that is supposed to be plugged with a rubber insert. If I remember correctly, it's partially hidden behind the computer that's mounted down there. The rubber plug had fallen out and was laying just below it. Without that plug, water being thrown up by the right front tire was making it's way into the cabin and soaking the carpet. Once I reinserted the insert plug, the problem went away. Not sure what caused it to fall out in the first place. Hasn't been a problem since.

I tried to find a picture or diagram, but couldn't. Sorry

If you see the plug/insert correctly in place, then I'd move to the sunroof drain issue next. Good luck!

That kickpanel rubber grommet...I spray foamed it

Just notice yesterday that my passenger carpet is wet. Don't have a sunroof and the rubber grommet is in place so now what should I look for?

Check the rubber accordion conduit between the door and the A pillar (by the door hinges). It is a press-fit into the A-pillar and door, and if dislodged, it can allow water to run inside the A-pillar and onto the carpet (behind the inside floor kick panel). Also check the conduit for rips / tears / cuts - it has numerous folds so you will have to examine each fold carefully.

Also check the body mounted rubber strip to ensure it is firmly seated on the body. The weather strip is a press-fit, and if loose, can be pulled off and squeezed with your fingers to tighten up the attachment point. If loose, or dislodged or torn, it can car allow water to run behind it, to the bottom of the body, then onto the floor carpet.
