NHTSA complaint: 2006 HUMMER H3 — ELECTRICAL SYSTEM
VEHICLE HAD HEATER BLOWER HARNESS AND RESISTOR FAIL AND CATCH FIRE FOR THE SECOND TIME. REPAIRED REPLACED ONCE BEFORE. THIS PARTICULAR PROBLEM OCCURS DUE TO A DESIGN DEFECT AND REPLACEMENT PARTS DO NOT CORRECT THE UNDERLYING PROBLEM AND IT WILL FAIL AGAIN. IT IS JUST A MATTER OF TIME. THE CIRCUITS SHOULD BE FUSE PROTECTED SO THIS WILL NOT BURN. PART NUMBERS HAVE BEEN CHANGED TO UPGRADE THIS CONNECTION TO NEWER DESIGN, BUT THESE PARTS ALSO FAIL. THIS IS A SERIOUS FAILURE OF THE ELECTRICAL SYSTEM. IN ADDITION, THE GROUND TERMINAL TO THE CHASSIS (BY THE INTAKE FILTER IN THE ENGINE COMPARTMENT) IS SUSPECT AS WELL. OVERALL THIS IS AN INCREDIBLY NEGLIGENTLY DESIGNED CIRCUIT. ONE CAN ALSO FIND NUMEROUS REPORTED FAILURES IN RELATED VEHICLES USING THE SAME PARTS. *TR
