    Default 2008 GMC Sierra Denali Tail Light Remove???

    I own a 2008 GMC Sierra Denali Truck and the left tail light has condensation in it. I was wondering if anybody had a DIY write up on how to remove the tail light? I want to see if there is a crack or if something else is wrong.

    If it is a 2008 it should still be under warranty, so I wouldnt mess with it myself.
    The only time I have ever seen them condensate inside is when the seal has been broken on the lens assembly itself. Either way, I dont think there is a way you can reseal it yourself, I believe they are a replace only item when the seal goes. But then I could be would not be the first time.
    Good luck to you.

    not only is it still under warranty [or should be anyway since its a barely a year old] but the taillights on my 06 silverado are held in by 2 phillips head screws. drop the tail gate and look to the inside and you will see two screws one at top and one at the bottom screwed in toward the outside of the truck, unscrew that and disconnect the bulb harness and thats it. it takes like 5 minutes, very simple.. only thing i can think as mentioned above is a seal is broke, take it to your dealer. if they wont touch it you can order LED tail lights on ebay for your truck that will look way better for somewhere around 150
