REAR hazard, brake, and turn signals dont work. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Like the title says, the REAR brake, hazard, and turn signals dont work. The front and sides work perfect but I'm having issues with the rear end. The clear reverse works and the ones that are supposed to be on at night work at the back but the others dont. I've checked the fuses, replaced the bulbs and checked the wires. What could it be? My dad thinks that it may be the pin switch but 12volts are running to the switch with a test light.

I'm so confused and I need rear lights! help please.

Here is a pic of the switches. It has two, one for the brake pedal and one for cruise control. (It doesnt have cruise control BTW.)

Tex: This may be the classic infamous trailer wireing problem. If you have a hitch connection look at it closely where wires are spliced in, then move up the truck harnace to the factory plug in for the rear lights, pull it appart and look for corrosion. Keep a test light with you and check at each step. If all is good and still no power back there, try plugging in a signal light switch and operating it. All the lights you mention go thru this switch, even the brake lights. Let us know, Jim

i have had the same problem, Mine was because the turn signal harness connector check that out. push them together good and see if they work might have to clean out the dirt in the connector maybe. good luck man that **** gets annoying to figure out.

Almost 2 years of work, but it was really worth the effort. Little stuff left to do is mount winch, wet sand & buff out and build belly pan\running boards. Body work takes lots and LOTS of beer!!!! God, Guts and Guns made America and God, Guts and Guns will preserve it! The worst thing you could do is get into my sights, but that don't matter, you'll never know it, cause you'll never hear the shotJim or Paladin whichever you choose.
