Hi! to the point! every light at the rear end of my 1988 chevy cheyenne doesnt not work or come on when it should. Head lights and running lights are fine. with headlights on, brake lights do not come on when brake is pushed in. whoever, they do come on when the clutch is pushed in. with the headlights off, the brake lights come on fine. either blinker come on as hazards. all known fuses were checked and replaced. all bulbs are fine. they just dont come on when they should or how they should. we have tried tracing all wires and they look fine.

The truck has been parked for around 2 years. the only things that have happened to the truck that may cause these problems are the headache rack with lights was removed and the rear end was replaced. Please someone help me!!! no idea what to look for next! Thank you!
