driver side carpet wet
on mine, what happened was that, some how the seal on the driver's door (the one covering the cables from door to side wall.)got unpluged from side wall,so when it's raining or you are washing the truck,a little bit of water would run inside eventually filling inside wall and cousing it flow out to the carpet.Maybe even to the door sinse the gasket connects to the door but you don't noticed because the door has it own water drain.What I did is that I got a water hose and started pouring water on the wind shield,hold it with the wiper so you can go inside the truck to observe what's going on,move it to diferent positions until I could find the leak. Hope it helps anyone!!!
