I REMEMBER DRIVING HOME ON THE INTERSTATE AND SMELLING A BURNING SMELL. I HAD THE WINDOWS OPEN BUT IT DIDN'T SEEM LIKE IT WAS COMING FROM OUTSIDE. LATER, THE CAR'S HVAC BLOWER FAN STOPPED WORKING. DURING REPAIR, THE BLOWER MOTOR RESISTOR AND THE HARNESS THAT PLUGS INTO IT WERE FOUND TO BE BADLY BURNED. THE HARNESS WIRES FOR GROUND AND POWER WERE MISSING INSULATION (BURNED AWAY) AND THE COPPER WAS BADLY CORRODED. THE TRIM PANEL DIRECTLY UNDER THE AFFECTED AREA HAS WATER STAINING AND SCORCH MARKS. BMW NA REFUSED TO PAY TO FIX DUE TO MILEAGE EVEN THOUGH CAR IS ONLY 4 YEARS OLD AND IS CLEARLY A WATER INTRUSION PROBLEM (LEADING TO A SHORT CIRCUIT AND BURNING) CAUSED BY EITHER A DESIGN OR MANUFACTURING ISSUE
