1990 GMC Truck V8 Four Wheel Drive Automatic 200000 miles
My front headlights and parking lights and hazzards work fine, but I have no Tail Lights, Reverse Lights Or Brake Lights. The Hazzards work in the back, but only if the headlights are turned off. When I push the brake pedal, the dash lights and radio turn on!
I can rebuild the 350 TBI in my sleep, but this puzzle has got me completely confused. I've changed out all of the relays and turnsignal fuses that I could find, and still no help.
Is there some sort of sensor on the brake pedal lever that controls the rear lights?
I can't drive for fear of getting rear ended, and i've tried every thing I can think of. The local shops have benn no help, but costly.
I'm seeing many posts with this samr problem so it has to be a single part, i'm thinking, that is faulty or wears out easily.
