Water in cab

[M1008driver]

We have been having heavy rain and I have been trying to solve the water in M1008 cab. I know about the side vent screws. My windshield do not leak, but there is a spot on the drivers side that looks like it is coming from the firewall.

These are not huge leaks, but enough I cannot put my rubber mat down without fixing them. Any ideas? My side vent void areas are clean with no debris.

Dry it up, cover inside with baby powder. Spray truck with water hose. Follow the runs.

That's a dang good idea. I will be doing the side vent screws when it dries up some.

EDIT- I think I found the culprit. Water is coming in around the side vents and some of the water runs along the frame and drops down to the floor. Seal the vent frame & screw holes and I should be GTG.
