I have a 08 cobalt, tail and dash lights have been a pain in my ass for just over a month now. Tried all the fuses they all work tried swapping the drl relay with the a/c relay but nothing. Popped out the the light switch that also controls the blinkers and replaced that but nothing there either. Brake lights work fine head lights work fine. I tested for any open circuits across the rear light cluster then to ground but nothing there either. Im one step away from taking the car apart and following the wires from start to end. Any help would be appreciated
