The rear drivers side floorboard is soaked every time it rains. It does it when parked too, so it is not coming from the bottom...anyone got a fix for this?

 

Have you lubricated or conditioned the weather seals? I use Armorall and it does an ok job at keeping them flexable. In the owners manual, they say to use a GM product (of course). I may give that a try to see if it's any better.

 

Yep. I doubt that would be it, it has done it since the truck was new...I use 2001 on all the plastics and wd-40 to clean the door jams.

 

hey buddy do yourself a favor. check the rear cab brake light. mine qwas leaking and running down the side to the floorboard.

 

I recall a TSB about rear window leakage... it could be coming from there as well

 

thanks guys I'm still looking for it...I removed the rear door panel yesterday and tested it w/ a waterhose. found a trickle where the rear door mechanism is. I adjusted that and no more trickle, but the small raised shelf area under the rear seat is also wet, so I must have another problem.

BTW: I tried to reduce the rear window wind noise by tightening the screw in that mechanism and broke the damn screw...
