So a few weeks ago I noticed my floor getting wet underneath my driver side mat. I didn’t think nothing of it but I recently found out that I have a leak somewhere. It is a 2002 Chevrolet Silverado 1500 Ext Cab. The driver side carpet gets wet and of course the insulation under it is soaked. I took the plastic piece that ran along side of the edge from the front to the back and noticed water was popped up in there also, then lifted the carpet (that was dry) in the back and the insulation under it was completely soaked. Any ideas of where a leak could be or has anyone else had this problem before?
