Wondering if anyone knows where to track this down. 86 Grand prix with a 3rd brake light.
My turn signals, hazard, and normal tail lamps work as normal, so that means all my wiring (at least from the column back) and bulbs are fine.
My brake lights (left and right tail lamps) don't work but the 3rd light does. That means the brake switch on the pedal is fine.
Is that something in the turn signal switch? I can't find an 86+ diagram to understand how the 3rd brake light works. I am having a hard time understanding how the 3rd brake light works but the tail lamps don't. Is there some diodes in the turn signal switch, or an additional harness that runs from the brake light switch back?
