GM, this headlight issue is now the 5th reason I will not be buying one of your trucks ever again. There are hundreds of people with this issue, across hundreds of models and years. No help, no answers.
I finally changed both bulbs out. Only one was actually burnt out though. The driver side was easy, but the passenger side made me want to kill every engineer that had anything to do with this truck's design. Only an hour of my time and 10 different tools, removing a dozen parts TO CHANGE A BULB. Thing better last.
**** you, GM. **** you and your overpriced nonsense.
