1994 GMC K2500 Brake lights don't work!!
I have a 1994 GMC K2500 that keeps blowing the STOP fuse when I press on the brake pedal. Even with a new brake light switch. Checked wiring- seems good-at least at the junctions and at the front and rear of the truck. Replaced the mother boards at the tailights. The brake light bulbs flash just before the fuse blows so they seem fine. I have not replaced the brake light relay because I can hear the relay click when the fuse blows. Any insights?
