Water in Tail Lights

Hello all. I have a 2011 Terrain SLT2. Ever since I purchased it, the right tail light has had water in it after a rain shower. When you open the rear hatch, it pours out through the hatch plastic getting wet whomever is standing under it. I've seen others mention it, but no one has offered a solution. I can't find a tear or separation in any of the gaskets or seals. Anyone have any suggestions?

my old Blazer had that happen too....I used some gunk to seal it which didn't really work so well so I drilled a weep hole at bottom of plastic to drain....worked well

Id recommend you find a used/salvage tail lamp on ebay or car-part.com and replace it. Its not hard to do..

2x on drilling a small drain hole. The most cost effective to do on a 9yr. old vehicle.
