I've noticed after a rain that the floor behind my driver seat is wet, I know it's coming from the roof somewhere but I haven't figured out where. Maybe the sunroof, or the back window. Maybe someone else has experienced this and can help me out.

Thanks.

 

regular cab, extended, supercrew? my last truck was a regular cab with a slider back window, and when there was a heavy rain the back window would leak from the top. it's probably your back window, or the seam around your door

 

Supercrew, I've actually narrowed it down to the sunroof or back window, cause i can see it rolling down the window when it rains.

 

Check the third brake light for leaks too. 97-9 models had problems with the rear window seals.

 

intresting...id go with window or door seal??
