Water Leaking In Cab

[landryd]

I've got a 2007 GMC 2500HD Classic 4X4 extended cab. Today my daughter noticed while riding out back there was water dripping down from the center rear edge of the headliner. Could this be coming from the window seal or the third brake light? I do not have the sliding rear window.

It happened to my 1999 nbs silverado. I took it to a glass shop and they said that the seal between the third brake light and the paint wasn't flush and lets water in. They put some caulking around it and it hasn't happened since. That was almost two years ago. Hope that helps.

yeah.. thats ur best bet.. some clear sealer around the tail light.

Fred started that about 6 months ago. I pulled the light out and put some silicone caulking around it and it's been fine since.
