2004 GMC Sierra Lighting Problems

MY 2004 GMC SIERRA WOULD LIGHT ALL FOUR TURN SIGNALS WHEN THE LEFT TURN SIGNAL WAS APPLIED, AS IF THE HAZARD LIGHTS WERE ON. TOOK IT TO DEALER AND THEY SAID THEY HAD NEVER SEEN ANYTHING LIKE IT BEFORE. PAID ALMOST 200 DOLLARS TO GET IT LOOKED AT AND FIXED. AFTER GOING HOME, I SEE THAT OTHER SIERRA USERS HAVE THE SAME PROBLEM. MORE SHOCKING, I SEE THAT GM HAD THE EXACT SAME PROBLEMS WITH SOME ENVOYS, BARBADOS, TRAILBLAZERS, AND OTHERS, AND PERFORMED A SAFETY RECALL AT NO CHARGE. IT IS OUTRAGEOUS THAT ALL VEHICLE OWNERS WITH THESE PROBLEMS WERE NOT NOTIFIED AND THE FAULTY COMPONENTS REPLACED. HAVE BEEN TRYING TO GET IN TOUCH WITH GM ABOUT THIS AND THEY HAVE YET TO SEND ME ANYTHING BUT CARBON-COPY E-MAILS AND RUNAROUNDS. *JB

2004 GMC 3500 PICKUP, PARK LIGHTS GOES OUT ON IT'S OWN. *BF THE CONSUMER DISCOVERED THE PARKING LIGHTS WERE HOOKED TO A BATTERY SAVING DEVICE THAT AUTOMATICALLY TURNED OFF THE LIGHTS THAT WERE LEFT ON AFTER A PERIOD OF 10 MINUTES. *JB

I OWN A 2004 GMC SIERRA PICKUP WITH 6,700 MILES. I AM EXPERIENCEING A IMTERMINTENT PROBLEM WITH THE TURN SIGNAL/HAZARD LIGHTS. WHEN I ACTIVATE THE LEFT TURN SIGNAL THE HAZARD LIGHTS BEGIN TO FLASH. I HAVE TAKEN THE TRUCK TO THE DEALERSHIP FOR REPAIRS, AFTER WAITING TWO MONTHS FOR THE PROBLEM TO OCCUR AT A TIME I WAS NEAR THE DEALER. THEY REPLACED THE MULTI FUNCTION SWITCH AND TWO DAYS LATER THE PROBLEM IS STILL THERE. I CONTINUE TO WORK WITH GMC DIRECTLY AND THE DEALERSHIP TO SEEK RESOLUTION BUT AM BEING TOLD THAT UNLESS THEY CAN SEE THE PROBLEM HAPPENING THEY CANNOT DO ANYTHING. I AM VERY CONCERNED THAT THIS IS A DEFINITE SAFETY ISSUE. IF I AM ATTEMPTING TO MAKE A LEFT TURN AND THE SIGNALS ARE NOT OPERATING AS THEY SHOULD I COULD END UP IN A COLLISION WITH ON COMING OR APPROACHING FROM THE REAR TRAFFIC. I BELIEVE THIS SHOULD BE ADDRESSED IMMEDIATELY AND REPAIRED. PLEASE HELP.*AK

THE DEALERSHIP WAS UNABLE TO INSTALL A RELAY SWITCH BECAUSE OF A WIRING CHANGE FROM THE 2000 MODELS. THE LOW AND HIGH BEAM CAME ON SEPARATELY. WHEN IT SNOWED AND THE HIGH BEAM WAS ON, SNOW BUILD UP ON THE LOW BEAM. WHEN THIS OCCURRED IT CREATED A LAYER OF SNOW, AND CONSUMER WAS UNABLE TO CHANGE BACK TO LOW BEAM. *AK THE MECHANICS REPORTED THAT THERE WAS AND INCOMPATIBILITY'S OF THE PREVIOUSLY USED RELAY. GMC WOULD NOT CORRECT THE PROBLEM. *SC
