Water leaks into the cab of my truck when It rains, obviously. It leaks onto the passenger side floor, near the front, to The left side of the fan area. Does anyone know where its coming from or an easy way to fix it or anything? I looked in the vent cowel area and didnt see any holes through the firewall area. And I can't see anything from underneath the dash. I imagine Its not much for the electrical components in that area and the floor. Thank you for any help!
