Hello, I have a 2013 GMC Sierra still under warranty with 28,000 miles and have the following problem. Moisture has built up in both the left front headlight and rear taillight. How do I get rid of this problem? I had the same problem with the right front headlight right after I purchased the vehicle. Then the dealer replaced it but they gave me a bad time stating that they really didn't have to because it wasn't a failure. Any suggestions? Is it a seal or does the main assembly have to be tightened? Thanks in advance

Ditto on what karlO said above. Keeping condensation out of light housings can be frustrating , but a drain hole in the ones that keep getting water inside despite attempts to seal them can limit the amount of water that accumulates. I saw a brand new vehicle recently that had about 2 inches of water sloshing around inside one tail light.
be sure to check the light over the rear window, my brothers 2011 leaked and started smelling musty inside the cab, they removed parts of the interior exposing the bare metal and coated the floor to prevent it from rusting
