I bought my 2012 silverado extended cab in July.
We had some really hard rain yesterday and today I noticed a little water in the cab on the sides of the floor near the door sills. I have read that the 3rd brake light can leak and sure enough there is water running down the inside of my rear window near the 3rd brake light.
So here are my questions:
-Do they only leak when they are cracked? Where do they crack? I can't see any cracks with it still installed.
-If its not cracked, could just the seal be bad? Replace the seal or just try some silicone, or both?
-Does anyone know the GM part number for the 3rd brake light for a 2012 silverado ext cab? is 25890530 correct?
-If you buy the GM replacement light, does it come with the gasket? If not, what is the gasket part number?
I'm glad this is where the water is leaking and not somewhere more difficult to diagnose or access...
Thanks in advance for your help.
