Water coming in

[Scalped]

had first hard rain today and waters coming in the cab into right floor board from behind side panel

Any guesses where it could be coming from?

Thx

could be a leaky windshield.  or a leak in the firewall. or a leak at the antenna.  or a dribble coming in through the gap above the door and running down the a-pillar.  our trucks are quite prone to leaks.  that's why our floorboards rot out so fast. :(  water trapped under the carpet.

baby powder can sometimes help find a leak.  sprinkle it around the area and the water will make tracks through it.
