MY HEATING AND AC BLOWER MOTOR STOPPED WORKING ON A VEHICLE THAT HAS LESS THAN 31K MILES ON IT. THE ESTIMATED REPAIR COSTS ARE 500$, NOT INCLUDING THE TOW, BEING THAT IT IS THE MIDDLE OF WINTER AND THE CLOSEST DEALERSHIP IS 20 MILES AWAY. ADDITIONALLY, THE TIME OFF OF WORK AND EBING WITHOUT A CAR FOR A WEEK. I HAVE HEAVILY RESEARCHED THIS ISSUE AND IT HAS BEEN REPORTED THOUSANDS OF TIMES AND IS A WELL KNOWN ISSUE AND GM HAS NOT ISSUED A RECALL. THE PROBLEM IS THAT A FAULTY ELECTRICAL SHORT CAUSES A WIRING HARNESS TO MELT, (SMOKING) WITH A BURNING SMELL AND BLACK RESIDUE. THIS IS A MAJOR FIRE HAZARD AND THE RECOMMENDED FIX FROM THE DEALERSHIP ONLY REPLACES THE HARNESS, BUY DOES NOT ADDRESS THE CORE ISSUE CAUSING THE FIRE HAZARD. THIS IS LIKE REPLACING BURNT DRYWALL TO ADDRESS FAULTY HOUSE WIRING . *TR

I WAS DRIVING HOME AND THE FAN ON THE A/C STOPPED WORKING. SHORTLY AFTERWARD I DETECTED A BURNING ODOR. I ENDED UP REPLACING THE RESISTOR AND WIRING HARNESS FOR THE A/C BLOWER MOTOR. THE RESISTOR WAS BURNT AND THE HARNESS WIRE WAS SLIGHTLY MELTED. I AM CONCERNED ABOUT THE POTENTIAL FOR A FIRE IF THIS HAPPENS AGAIN. *TR
