NHTSA complaint: 2006 GMC ENVOY — ELECTRICAL SYSTEM
HAD PROBLEMS WITH THE HEATER'S BLOWER MOTOR NOT BLOWING OR SOMETIMES BLOWING BUT NOT ON EVERY SPEED. LOOKED UP ISSUE ON YOUTUBE AND FOUND MANY VIDEOS OF THE SAME ISSUE AND THE VIDEOS SHOWED THEM HAVING TO REPLACE THE HEATER'S BLOWER MOTOR RESISTER. AS THE RESISTER WAS BEING REPLACED, WE NOTICED THE RESISTER WAS MELTED ONTO THE PLUG IT PLUGS INTO AND THE THICK RED WIRE WAS ALSO MELTED. RESISTER GOT REPLACED AND THE BLOWER SPEEDS ALL WORKED AGAIN. SHORTLY AFTER INSTALLATION OF THE NEW RESISTER, THE NUMBER 5 SPEED FAILED BUT ALL OTHERS CONTINUED. THREE MONTHS LATER, THE RESISTER FAILED. EXCHANGED AND REPLACED THE RESISTER AGAIN AND WORKED ON ALL SPEEDS BUT 5 AGAIN. HAD A SMELL TO IT WHILE IN USE, WE GOT USE TO IT AND THOUGHT NOTHING OF IT ANYMORE. WORKED FOR OVER 2 YEARS UNTIL 1/12/2019 WHEN AS THE ENVOY WAS IN MY YARD WARMING UP IN BELOW FREEZING TEMPERATURES, THE VEHICLE CAUGHT FIRE WITHOUT AND WARNING AND BURNED UNDER THE GLOVE BOX CATCHING THE CONTENTS IN THE GLOVE BOX ON FIRE AND MAKING THE VEHICLE BURST INTO FLAMES AND EVEN HAD AN EXPLOSION INSIDE THE VEHICLE. BLACK SMOKE WAS POURING OUT ON THE AREA OF THE PASSENGER SIDE WINDSHIELD WIPER AREA. THERE WAS A HOLE IN THE WINDSHIELD ABOVE THE WIPER.
