Hello. I have a 2010 4 door wrangler and I noticed that the passenger side carpet is damp, however I did not see any rain water coming. It does not smell like anti freeze. I have the floor mat that came with the vehicle, and another heavy weather tech mat on top. I lifted out the carpet and found nothing wet, but the left side of the floor where the exhaust is was very hot and there is a warning sticker to tell you that. Could it be that condensation is forming between the rug and the two mats? Driver side is fine, and the rear driver side was also a little damp, with the same carpet set up.
I removed the mats, for a day so far and have not seen any moisture.
Yes, I ran the ac and the heat.
