[Devin Montgomery]

Hey yall in my 2011 GMC Sierra 1500 5.3L I have noticed that my radio has quit going bright in the daytime even after screwing with turning headlights on and off, still wont come on. Does anybody have any Idea what is wrong with this truck.

Maybe you've already checked, but have you adjusted the interior lighting knob?
