Consumer Description

LOSS OF FAN - BLOWER MOTOR (HVAC) HIGH SPEED OPERATION FAILURE. WITH LOSS OF HIGH SPEED FAN, OTHER FAN SPEEDS (LOWER) OPERATION BECAME INTERMITTENT, WORKS AFTER JIGGLING BLOWER MOTOR WIRE BUNDLE AT CONNECTION POINT ON BLOWER MOTOR RESISTOR. VISUAL INSPECTION SHOWS MELTED WIRE HARNESS CONNECTOR AT BLOWER MOTOR RESISTOR, UNABLE TO SEPARATE (REMOVE) THE CONNECTOR. SEARCHED NHTSA ODI DATABASE AND FOUND THREE VERY RELATED DEFECT COMPLAINTS - INOP FAN, SMOKE AND MELTED WIRES, FAN LOSS. FAN FAILURE COULD LEAD TO FIRE FROM MELTED ELECTRICAL CONNECTIONS, LOSS OF VISIBILITY DUE TO WINDSHIELD ICING IN WINTER, FOGGING OVER WHEN DRIVING IN CHANGING WEATHER. WINDSHIELD DEFROSTER REQUIRES OPERATIVE FAN AND DEFROSTER IS A REQUIRED SAFETY ITEM. DEALER REPLACED BLOWER MOTOR ELECTRICAL CONNECTOR, WIRE HARNESS, AND FUSE, CHARGING PARTS TO WARRANTY AND ME FOR THE LABOR. THIS APPEARS TO BE A VERY COMMON DEFECT IN THIS PRODUCT LINE. THERE IS A TECHNICAL SERVICE BULLETIN FOR THE REPAIR INCLUDING REPLACEMENT OF THE CONNECTION WIRING TO INSURE ANY MELTED INSULATION IS REMOVED. THIS SHOULD BE A SAFETY RECALL. DEALER HAS OLD PARTS. *TR
