Hey all. I have a 1981 GMC 4x4 pick-up. The rear turn signals work fine and the brake lights work on rear passenger side only. I pretty sure the brake light and turn signal circuits use the same filament in light bulb. I tested the wires coming down the drivers side framerail and no drivers side brake light on drivers side turn signal wire. Does any one know where the brake light circuit enters the turn signal circuit before I start looking for cause of problem? Many thanks in advance.
