drivers floorboard wet sitting during rain

[Justin Yount]

I verified the 3rd brake light is dry behind it, the bulkhead connector to the door is dry, the rear floor is dry.  The only evidence is drivers pad and carpet are soaked and water is in the wiring trough near the pinch weld of the door.  The nuts holding it down are rusty, so water has been there.  The wiper cowl drains are clean.  I bought this truck used, so i have  no idea on glass.  I pulled the bed liner out to clean out the bark under it,  he must've hauled wood, so back glass replacement is possible previous owner.  Cab vent?  Can't see it, behind trim.  I have the door sill trim, the kick panel, and the carpet pulled back.  No pics at this time.  Raining hard right now.

Sunroof?  If so, the drain for it (runs down the A-pillar) could be plugged

Sit in the truck and have someone spray water on roof, windshield, etc and see if you can see where/how the water is getting in

I had wet carpet in my '06 Avalanche. I took it to a glass shop and the cleaned the Sun roof drains, no more wet carpet. Your windshield could be leaking. The PO might have installed a new W/S, if you don't know how to do this (it's not hard to do but you have to know how) it's easy to mess up. You could have a glass shop reseal the W/S, I would pay them to fully remove and reinstall it though. They might want  to chase the leak (if it is indeed in the W/S) but I recommend cutting to the chase and have it fully removed, the opening cleaned along with the glass. I'd be thinking about pulling the carpet come summer time, hang it up and pressure wash it and let it dry thoroughly; or hey, you can replace it, there are many sellers.

I was going to say windshield as well, thought I commented but guess not.

I had a windshield leak that led to my passenger floorboard getting soaked. When I tried to find it myself I never could find any drops of water at all. Just replaced it because I had cracks in it and it was only $125. Turned out to fix the problem.

                                                                                    No Sunroof or cabinets.  If the cab vents leak does the trim route it through that door seal.  If no that must be over runningthdoor seal.    Too cold to hose it now.     ice on the ground and below freezing.  What sucks is I can't see the seal in the truck.      When it gets wet  I've been using my carpet extractor  On the pad and carpet.
