I have a 2006 Sierra and I am having problems with my driver side brake/ tail lights. They both work independently, but when I press my brake pedal the tail light goes off and the brake light will not light. Any ideas?
As mentioned, sounds like wiring problems and those can be hard to track down. If you have any aftermarket or half-a$$ed trailer wiring then thats the first place I would look. Most trailering wiring added to the truck is rarely done right and that later can present major wiring problems the new owner is left to fight with.
