Hey everyone! This is my first post but I have been here doing lots of reading. I did do a search and nothing seemed to pinpoint my exact problem. I have a 1981 short bed c-10 auto with a 454 motor. Every light on my truck works. Headlights tails blinkers back up, everything except the brake lights. The switch is new and I cant find any bad grounds that I know of. Must be behind the dash or in the steering column or something. Any help as far as a starting point would be great before I tear my dash apart. Thanks!
