My drivers floor was pretty wet after one of those all day rains. The floor mat wasn't wet and it wasn't wet under the seat or along the door edge. It's not wet after washing the truck by hose which takes about 30 mins. I need to find the source quick because I don't have a garage to keep it in. The carpet is also new but installed in the summer when it hardly rained so I didn't realize it. The door weatherstrip looks good and the firewall main wiring harness grommet has been fixed. Where are other common areas to check?
