NHTSA Complaint #10350400 — 2004 TOYOTA HIGHLANDER

THE TEMPERATURE CONTROL ON MY 2004 TOYOTA HIGHLANDER KEEPS SWITCHING BY ITSELF FROM HOT TO COLD AND HOT AGAIN. I HAVE TO ACTUALLY TURN THE AC ON EVEN WHEN THE OUTSIDE AIR COMING IN IS MODERATE BECAUSE THE TEMPERATURE CONTROL WILL SWITCH BY ITSELF TO HOT AND I CAN'T SWITCH IT OFF. THIS OCCURS EVERY TIME I DRIVE AND MORE SO WHEN I GO OVER A BUMP OR MAKE A TURN. I TURN THE VENT ON FOR OUTSIDE AIR, BUT THE TEMPERATURE CONTROL GETS LOCKED ON TO HOT AND I CAN'T TURN IT OFF. I HAVE CALLED THE DEALER AND THEY HAVE SAID THAT IT WOULD COST AROUND $1000.00 TO FIX IT. THEY WANT TO REPLACE THE WHOLE CONTROL UNIT. I HAVE READ VARIOUS FORUMS OF NUMEROUS OWNERS HAVING THIS SAME ISSUE. IT SEEMS TO BE A PROBLEM WITH TOYOTA NOT LEAVING ENOUGH SLACK IN A RIBBON CABLE WITH 3 CONNECTIONS THAT CONNECT FROM THE CIRCUIT BOARD TO THE CONTROL KNOB. THE WIRES BREAK OFF FROM THE SOLDERING ON THE KNOB. THIS SOUNDS LIKE A KNOWN DEFECT TO ME THAT TOYOTA IS AWARE OF, BUT CHOOSES TO IGNORE. APPARENTLY A CHEAPER FIX IS TO RE-SOLDER THE CABLE, BUT THEY REFUSED TO DO THAT. I THINK THEY SHOULD BE FIXING THIS FOR FREE. THIS IS JUST ANOTHER EXAMPLE OF TOYOTA IGNORING KNOWN ISSUES WITH THEIR VEHICLES. *TR
