OK I have a leak in my truck and need help. Yesterday it was raining all day and I touched my headliner about my passenger seat. (I put my hand on the seat some times) And when I did this it was all wet. I ran my hand across the whole bottom of the headliner and it was all wet. So that means there has to be a leak somewhere.

So does anyone know where it would be coming from? I was thinking the third brake light or the rear window but am not sure. How would I check? Its almost winter so I need to get this fixed.

 

3rd brake light. common issue.

 

yea

 

Yep, 3rd brake light. Mine did the same thing when I first got it.

Pull the brake light off, run a bead of silicone around it, then put it back on. Shouldn't leak after that.

 

not ness....I still cant find my leak...best option check to see if your window seal outside is touching your truck or if its gapped...I would get liquid silicone run a bead around the whole back glass and the 3rd brake light....And be done with it....Im still thinking water is coming in from those molding pieces at the top??
