Truck is in the shop now and they’ve determined the water is not coming in through the sun roof or windshield. Now body shop is tearing into it....anyone have any idea what’s going on. Right now no one has a clue.
water is on the drivers side floor board and inside the rail where all the electrical wiring is located.

 

did this ever get resolved my 19 f250 is doing the same thing after rain

 

Sometimes a mild dusting with talcum powder in the area will reveal the entrance of the water.. A good wetting with a garden hose in place of rain should help show the area.
