NHTSA Complaint #10206018 — 1999 JEEP GRAND CHEROKEE

THE "BLOWER CONTROL MODULE" IS THE ELECTRONIC COMPONENT RESPONSIBLE FOR ADJUSTING THE FAN SPEED FOR THE HVAC ON VEHICLES EQUIPPED WITH THE AUTOMATIC CLIMATE CONTROL. IT IS A WELL KNOWN PROBLEM THAT THESE UNITS FAIL. IT HAS FAILED ON MY VEHICLE. MY OWN INDEPENDENT MECHANIC HAS REPLACED QUITE A FEW OF THEM. THE WIRING HARNESS AND PLUG THAT SUPPLIES POWER IS NOT HEAVY DUTY ENOUGH AND IT OVERHEATS AND MELTS AND COULD CAUSE A FIRE. IT CAN BE FURTHER EXAGGERATED IF THE BLOWER COLLECTS DEBRIS AND DRAWS MORE CURRENT. ONCE IT FAILS THE BLOWER WILL NO LONGER OPERATE. THIS MAKES THE DEFROSTER UNAVAILABLE, WHICH COULD CREATE VERY UNSAFE DRIVING CONDITIONS SHOULD THE WINDOWS FOG UP. CHRYSLER HAS A REDESIGNED UNIT WITH A NEW HARNESS SO IT IS OBVIOUSLY A PROBLEM THEY ARE ALREADY AWARE OF. I'M IN THE PROCESS OF HAVING THE NEW PARTS INSTALLED AND THE OLD PARTS WILL BE AVAILABLE. HERE'S A WRITE UP OF HOW TO FIX IT YOURSELF. HTTP://WWW.WJJEEPS.COM/BLOWER_MOTOR.HTM *JB
