NHTSA complaint: 2005 CHEVROLET TRAILBLAZER — VISIBILITY
BLOWER MOTORS NOT WORKING, REPLACING THE PART, AND FINDING THE WIRING IS MELTED AND SHORTING OUT ON THE HEATER CONTROL MODULE RIGHT SIDE OR REFERRED TO AS THE RESISTOR. THERE HAS BEEN NO RECALL ON THIS PART, BUT WE HAVE FOUND SEVERAL VEHICLES WITH THIS PART HAVE THE SAME ELECTRICAL MALFUNCTIONS WHICH ARE CAUSING OTHER MALFUNCTIONS IN THE VEHICLE. TO REMEDY THE PROBLEM THEY NEED TO UPDATE THE HEATER CONTROL MODULE ON THE RIGHT SIDE OR REFERRED TO AS THE RESISTOR. THIS IS THE PROBLEM. *TR
