I have an 07 SCREW. I live in South Texas and we have had 12 inches of rain in the last 3 days. Today when i got off work my truck smelt really bad. I looked for a reason and saw that the back corner on the passenger side head liner was wet. When I got home and investigated, it was totally soaked and it runs all the way behind the plastic shield thing in the corner. The carpet in the back corner all the way down to the front passenger seat is soaked. Why?

I took the third break light off thinking it might be from there, but it was dry underneath. What else could be causing the leak and why now being that its been in the rain for a week now?

Thanks for any help!!

 

is your door not shutting all the way?? other than that there is the good ol' 3rd brake light tsb.

 

As far as I know it is. But why would only the corner be wet, which is behind the door.

And what do you mean by third brake light "tsb"? I removed the entire housing and it was dry underneath.

 

the technical service bulletin that concerns the leaking third brakelight housings on your generation f150. and just because it is dry where you removed it does not mean it does not leak. water flows and your truck might have been angled in such a way as that the corner is where the water finally made contact with the headliner.

 

My 08 leaked thru the 3rd brake light, almost fried my amp. Resealed it, no more leaks.

I'm in Texas too.
