The contact owns a 2003 GMC Envoy. The contact stated that the headlights ceased to operate as needed. Upon taking the vehicle to a local Pep Boys, it was diagnosed that the electrical wiring harness was burned and needed to be replaced. Additionally, the bulbs needed to be replaced. The contact stated that the vehicle was repaired; however, the failure recurred. The vehicle was taken back the local Pep Boys, who replaced the electrical wiring harness and the bulbs a second time; however, the failure persisted. The dealer and the manufacturer were not notified of the failure. The vehicle was not repaired. The failure mileage was unknown.

Back door latches sticking/very hard to open and at times won’t open at all. Visibility from wipers is very limited and not good. Rear exterior lights at times flicker and bulbs come loose at times

HEADLIGHTS AND BRAKE LIGHTS WENT OUT AT SAME TIME. HIGH BEAMS WORK, VEHICLE RUNS, HAS ALL POWERS. THIS HAPPENED WHEN I LEFT THE HOUSE, WHILE DRIVING, NOTICED WHEN IT BEGAN TO TURN INTO EARLY EVENING.

WHEN TRAILER IS CONNECTED TO THE 7 WAY TO BOX TRAILER CONNECTION TRAILER TAIL LAMPS DO NOT LIGHT CORRECTLY. BRAKE AND LEFT TURN SIGNAL LAMPS WORK PROPERLY. THE RIGHT TURN TRAILER LAMP IS PARTIALLY LIT WHEN TURN SIGNAL IS NOT ENGAGED. WHEN RIGHT TURN SIGNAL IS ENGAGED THE LEFT AND RIGHT TURN SIGNALS START FLASHING, BRAKE LIGHTS WORK NORMAL. THIS TURN SIGNAL ISSUE APPLY ONLY WHEN TRAILER ELECTRIC CIRCUIT IS PLUNGED IN TO THE TRAILER CIRCUIT. MY UNDERSTANDING THERE WAS A RECALL REGARDING THE FLASHER UNIT FOR THE 2003 ENVOY VEHICLE TURN SIGNALS. IT APPEARS THE TRAILER CIRCUIT HAS A SIMILAR ISSUE. BOTH THE VEHICLE AND TRAILER WORK OFF THE SAME FLASHER MODULE. SEE RECALL 05V198000. I PLAN TO REPLACE THE FLASHER UNIT TO CORRECT THIS DEFECT. IF YOU NEVER TOWED A TRAILER THIS ISSUE WOULD NOT BE DISCOVERED. WHEN TOWING A TRAILER DRIVER COULD BECOME CONFUSED WHEN YOUR MAKING...
