Wet Carpet Under Floor Mat.....

fbachman · April 25, 2011

Took out the Weatertechs to clean them.

Noticed the carpet is wet on the driver's side, about four inches forward of the lawyer hook that holds the WT in place. Checked the WT for a hole, leak and nothing.

I can't figure this one out.

I did a search, and did not find anything particualr to this. Can't figure out where it is coming from. There is no "trail" of wetness from an area that may indicate the origin.

It's jsut a 3-4" diameter circle of wet carpet in the area described above.

Any ideas?

I know they were originally blaming it on people carrying snow into the car and it melting and getting in the carpet and never drying because of the padding. They put out a recall on that so the padding could be cut out around an electronic module under the carpet there. I'd be surprised if this was your issue however with the weathertechs. Just what came to my mind though.

check to see if your cab vents are installed as mine were not and i had the same problem! they are the vents locted in between the cab of the truck and the bed. its a 3x5 plug that should be on both sides

If I understand correctly, it sounds like the carpet is only wet under the drivers feet in a small area. With the back vents missing, seems like the carpet would be wet most of the way back also.

Grumpy,

By chance, is there a grommet in the floorboard in that area (or suppose to be there!)? Just a thought!

Good luck, and keep us posted!

Could it be that it was wet in a much larger area a few months ago and now it is almost dried up? Perhaps some snow melt or ?? and it is drying slow because it is covered??

i have the same exact problem in my 2001 silverado. just pulled the mats out the other day and the carpets smell musty and are moist on both the driver and passenger side. pulled up the carpets, figure its definatley the big grommet on the drivers side so i caulked it. now on the passengers side theres no grommet and even more moisture! sprayed everywhere with the garden hose and couldnt find anything..... no idea where its coming from on the passenger side.... unless its from peoples feet that somehow got under the mat.

Didn't think about the door sill channel! Makes sense!

Need to check my truck after reading this!

I had the same issue along the passenger side. It smelled all musty so I started feeling around and my carpet was soaked. Turns out the seal on my sunroof was bad and water was pooling up. I don't know how it got down there, but the ceiling was completely dry. It took Chevy 3 days to fix because of testing and re-sealing.

wow, i'll check the vents in the AM and report back.....

great input, much appreciated.

The one post I did not want to see. We got rid of a 2000 Passat because of the same problems. Water came in through the sunroof when the drains would clog up and through the cabin filter housing.

well, the cab vents are there and, from what I can make out, installed flush to the back wall of the cab as seen by peeking between the bad and cab wall.

From where you said the leak is and the size I would really check this..

Its the groument the E-Brake cable goes through, I'd crawl under the truck with a hose and spray the hell out of it and see if the carpet gets any wetter, also I had an S-10 that had a similar problem and it was the groument around the steering shaft going through the firewall.

fbachman · April 28, 2011

that's awesome. Unbelievable that you had a perfect picture at hand. I appreciate that.

If I am judging the location correctly, that sure looks like the right location. Am I correct to assume that this is the driver's side, and I am looking at the seat rail along the bottom of the picture there? Clearly you have the seat out, and looks like you were running some wires for something there.

Yeah its the drivers side about 6-8 inches in board from the pinch weld under the door sill plastic . This pic is from a rear view camera install thread.
