2005 CHEVY 1500 SILVERADO - HEATER BLOWS HOT AIR ON DRIVERS SIDE, COLD ON PASSENGER SIDE - HAPPENS WITHOUT NOTICE - HAVE SPENT AROUND $300.00 (+) DOLLARS TRYING TO FIX THIS. WAS TOLD BY GM SERVICE TECH IT WAS THE HEATER MOTOR RESISTOR WIRING HARNESS, IT BURNS OUT THE RESISTOR. I REPLACED BOTH, THE RESISTOR BURNED OUT AGAIN AND THE WIRING HARNESS WAS FRIED AGAIN. THE INTERNET IS FULL OF THESE REPORTS - A RECALL IS NEEDED - THIS CONDITION IS NOT SAFE. THANK YOU FOR YOUR HELP. *TR
