2nd Gen Non-Engine/Transmission 3rd Brake Light leakage

[DKothe]

My son caught a neck full of water while sitting in the back seat of my '99 when I turned a corner. I checked with the TDR list and found that the 3rd Brake Light could be a sourse of water leakage into the cab.

I pulled the two phillips head screws that hold the light in the cab. When I pulled the light out of the hole I could tell immediatly that the gasket wasn't touching completely across the top section.

Since I'm cheap and I also had the clear silicon sealant on hand... ... ..... easy fix.

Cleaned the cab surface of dirt and wax, left a good layer of silicon sealant where the gasket should rest against the cab.

Installed the 3rd Brake Light and snugged the 2 screws down into place.

The excess silicon was squeezed out of the gasket area and immediatly wiped up.

I have had no more leakeage into the cab since and it only took a few minutes, a tube of clear silicon sealant and a phillips screwdriver.

I dealt with wet floors for quite some time and even bought a new gasket for the cab light. What I found to be leaking was the rubber seal around the back window. I used a silicone caulking gun with the tip placed under the seal lip and pumped a bead all along the top and sides under the seal then pushed it back in place and wiped the excess. After literally years of head scratching I now have a dry cab.
