hope someone can point me in the right direction. I have brake lights and reverse lights. headlights come on but the rear tail lights do not. turn signals work. is there a flasher that I should be looking for? appreciate the help. John
replaced all bulbs, just to make sure. using a test light, I've confirmed there is no juice on that circuit
It sounds like a bad wire or connection to me. Find the plug for the back wiring in the cab. I think it's under the floor mat/carpet between the passenger seat and the door, but that's on an 86. There will be a connector somewhere though. Check and see if you get voltage there. Trace it back or forward until you find the fault.
