Water leak at high mount stop light on Ford F-150
2009 Ford F-150 41,000 mi, Visitor
Water leaking on left passenger side near rear of truck. Gets headliner all wet. Dealer told me two years ago it was third brake light. Changed light twice and two years later still not fixed. Sealed light completely and it rained on 11/2/2015.Headliner still got wet. Brake Light was dry when cover was removed.I now believe it is the small black trim piece that is riveted to the roof above rear window. Has anyone else had this happen.

Leak was noticed during heavy rain @ the passenger door hand hold, Later noticed @ the 2 rear corners of the back window. Investigating Repair.
Water leaks that appear at the headliner and rear seat area have been known to be coming from the rear high mount stop light. The gasket that seals the light becomes warped over time and allows water to enter through the stop light into the cab area. A revised stop light is available, but I have found that properly placed caulk or foam tape will work also.
have the exact problem. It has been going on I was convinced it was coming from the seal on the door. After reading this I checked and yep it's from the cargo light. You would think ford would have fixed it by now.

Mine did this too. Dealer replaced the gasket at the third brake light and the gasket for the whole back window. 6 months later (and after warranty expired) it began to leak again. The replacement of the gasket for the back window never did correct the whole window assembly from shifting and squeaking. Only leaked during extremely hard rain or in a car wash but a steady flow of water leaked in each time.

Leaked through the 3rd brake light into the cabin. I replaced the old gasket with a rubberized foam weather stripping from Home Depot and it seems to be working fine.
Third brake light always has moisture within the light assembly. This led to moisture getting into the roof of the cab causing water damage. A workaround by previous owner to seal the inside was performed but light was never replaced.

Water leak started a couple of weeks ago and has only gotten worse. It would have been nice if they could have sent a notice to owners so that the problem could have been fixed before causing so much water damage and inconvenience. So Ford saves a couple of bucks by using a cheap gasket, and owners wind up spending hundreds in repair costs. Nice!

Dealer told me that warrantee did not cover any leaks. I used silicone and it worked.

I have water leaks at the 3rd Brake light, and the satellite antenna, Took to dealer and they wanted $740.00 to fix this problem. I don't mind spending money on reasonable fair and tear items, but this problem is a design flaw. Ford has known about this for years, and they recommend a bead of silicone 1/8 " be placed were the gaskets should be. Local, dealer pulled my antenna and it had silicone from the factory... go figure, cost $53. for a new antenna, and I got charged $390.00 for the labor. I opted to purchase a new brake light and install it my self, this was another $100. You would have thought that someone would have made a replacement gasket but that would make too much sense, so either you go with the silicone, a new Ford brake light, or an after market brake light that on average are $35.00. I called Ford about this problem, but don't really expect them to react as they have known about this problem on the trucks since 1998-1999.
