NHTSA Complaint #10205425 — 2003 GMC ENVOY

2 COMPLAINTS NOTICED ENGINEE RUNNING HOT, ADDED FLUID TO RADIATOR, NEAR EMPTY. A COUPLE OF MONTHS LATER, SAME THING. 3 MONTHS LATER, DURING OIL CHANGE, MECHANIC INDICATED WHILE DOING CHECKS THAT THE RADIATOR FLUID WAS LOW. TOLD HIM THIS WAS THE THIRD TIME, HE ADDED FLUID, PRESSURE CHECKED RADIATOR - NO HOLES OR LEAKS. SEEMS TO BE EVAPORATING. AIR CONDITIONER BLOWING HOT AIR (EXCLUDING THE FACT THE PANEL WITH AC CONTROLS QUICK WORKING A LOOOONNG TIME AGO). TOOK IN TO DEALER FOR REPAIR. AFTER $600 AND ALL DAY VISIT WITH DEALER, THE PIECE BROKEN WAS THE SIZE OF A 2"-4" BLOCK OF PLASTIC. THIS LITTLE PIECE JUST QUICK WORKING, IT WAS REFERRED AS A CONTROL SWITCH OF SOME SORT UNDER THE DASH BOARD. SOUNDED KINDA HOKEY TO ME - I CAN IMAGINE A COMPRESSOR GOING OUT AND YOU DO NOT HAVE COLD AIR - THE NAME OF IT ESCAPES ME - BUT THE MECHANIC DID INDICATE THERE WAS SOME SORT OF TECHNICAL REPORT OUT THERE ON IT AS WELL. JUST FOUND OUT FROM HUSBAND THE NAME OF THE PIECE - THE ACTUATOR DOOR QUIT. *JB
