Hey,
2003 gmc 1500hd
Noticed my floor board on my drivers seat was wet a few months ago. Tried tracking where the water is coming from with no luck. Sat in the truck while I had someone spray water on it. Best I could tell was it was coming from the drivers door seal so I replaced that. Door closes much tighter now, almost too tight but it still has the leak.
Checked the third brake light. Looked dry.
My only other thoughts are get the windshield resealed or the trim at the top, back of the cab looks brittle and kind of cracking. Maybe that could be the source???
Any thoughts or advice would appreciated.
Thanks in advance!
