My 2003 gmc envoy tail lights does not work ,I replace the fuses and they still don't work ,,I don't know if there is a relay for tail light ,,can someone please help
Rear tail lights and brake lights not working. Turn signal works on outside but not on the inside. Bulbs replaced and it still didn't fix the problem. Still checking into the Tail Light Wiring Harness. This has been a wonderful vehicle and engine still runs great. Sorry to think that an electrical problem could take us out of commission when it still runs so good!
The right backup light stopped working. I disassembled the light fixture and found the socket and bulb had rusted together. The GMC parts man told me it was a common problem and I had to replace the whole wiring harness. I bought a new wiring harness and replaced the old one. Not a simple job but not complicated either.
My left rear blinker bulb quit. The yellow wire leading to it from around the ceiling has abraded and grounded it out.
The driver side rear brake light bulb has to be changed a couple of months. Water gets into the lens compartment and droplets form inside. I can't seem to get the assembly to seal.
Right rear blinker is not working. I have rewired everything and still not working. It blinks normal starting out then speeds up
My Left Brake Light was Very Dim (Compared to the Right) And wasn't working sometimes. It would go out. Had the Wiring Harness for Left Brake Light Replaced...Now Works Perfectly.
Right taillight failed. Replaced and problem solved, but problem recurred at 175,000 and had to be replaced again.
