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

I PURCHASED A 2014 JEEP GRAND CHEROKEE LIMITED FOR $46,000 FROM DOTHAN CHRYSLER DODGE JEEP RAM ON SATURDAY, AUGUST 17TH, 2013. WE DROVE OFF THE AT 8:30 P.M. THAT EVENING. ON MONDAY, AUGUST 19TH, AT APPROXIMATELY 4:00 P.M. AS I WAS DRIVING DOWN THE HIGHWAY AFTER HAVING JUST LEFT MY JOB AT THE WASHINGTON COUNTY SHERIFF' OFFICE, WHERE I AM THE PUBLIC INFORMATION OFFICER, MY VEHICLE'S SCREEN FLASHED A WARNING THAT READ: VEHICLE GEAR SHIFT MALFUNCTION. THE SCREEN WENT COMPLETELY BLACK FOR APPROXIMATELY 1 MINUTE. WHEN IT CAME BACK ON THE SCREEN READ: PLEASE SERVICE TRANSMISSION FOLLOWED BY TURN OFF IGNITION TO ENGAGE PARK. I TRIED TO TURN OFF IGNITION, IN THE MIDDLE OF THE HIGHWAY, AND THE WARNING THEN READ: VEHICLE MUST BE IN PARK TO TURN OFF IGNITION. THIS ENDLESS CIRCLE CONTINUED AS I WAS ABLE TO STOP THE CAR AT A GAS STATION PARKING LOT. I SAT IN THE PARKING LOT OF THE GAS STATION FOR APPROXIMATELY 5-7 MINUTES WHERE I DOCUMENTED (VIA CELLPHONE CAMERA) THE REPEATED MESSAGES AND ATTEMPTED TO TURN MY ENGINE OFF AND SIMULTANEOUSLY ATTEMPTED TO PUT THE VEHICLE IN PARK. THE GEARS WOULD NOT DISPLAY. THERE WAS NO WAY TO SEE IF THE VEHICLE WAS IN PARK, OR WHAT GEAR IT WAS IN AT ALL. AFTER STRUGGLING WITH THE VEHICLE FOR CLOSE TO 7 MINUTES, I WAS FINALLY ABLE TO TURN THE IGNITION OFF. WHEN I RESTARTED THE VEHICLE, THE TRANSMISSION SERVICE LIGHT WAS ON. I CONTACTED THE DEALERSHIP (AS NOTED ABOVE) IMMEDIATELY. I WAS ASSURED BY THE SALESMAN THAT THIS "HAPPENS ALL THE TIME TO JEEPS". THIS WAS MY FIRST MAJOR CONCERN WITH NOT ONLY THE VEHICLE, BUT ALSO THE DEALERSHIP. I HAVE A FULL TEAM OF CERTIFIED MECHANICS THAT WORK FOR OUR OFFICE. I MET WITH EACH OF THEM AND WAS TOLD THAT THIS WAS NOT A COMMON THING FOR ANY VEHICLE. MY CRUISE CONTROL IS NOW COMPLETELY INOPERABLE. *TR
