QuestionQUESTION: The fan to blow the AC in the car only works on high. Any idea where to start to look for this? Are there separate fuses for the lower speeds?
ANSWER: HI GAIL, SORRY THIS TOOK SO LONG. I WISH ALL MY QUESTIONS WERE THIS EASY !!! GO TO YOUR LOCAL GM DEALER AND PICK YOURSELF UP A BLOWER MOTOR RESISTOR. [DO NOT GET A AFTERMARKET] THIS IS COMMON PROBLEM,YOU DID NOT TELL ME THE YEAR OF THIS SO I WILL ALSO TELL YOU TO CK WITH YOUR DEALER IT MAYBE UNDER RECALL FOR THIS PROBLEM WITH RESISTOR WIRING HARNESS CONNECTOR BURNING UP AT THE RESISTOR ITSELF. YOU WILL NEED TO GIVE THEM YOUR VEH ID#..IF IT IS NOT UNDER RECALL, OPEN THE PASS DOOR AND LOOK UNDER THE GLOVE BOX AREA BY THE HEATER DUCT WORK ABOUT HALF WAY UP FROM THE FLOOR. LOOK AT THE NEW RESSITOR IN YOUR HAND AND FIND THE PLUG THAT LOOKS LIKE WHAT YOU HAVE AND REMOVE THE 2 SCREWS THAT HOLD IT TO THE DUCT PANEL,UNCLIP THE HARNESS AND INSTALL THE NEW RESISTOR. MAKE SURE THAT IF THIS IS NOT UNDER RECALL THAT WHEN YOU REPLACE THE RESISTOR THAT THE HARNESS PLUG THAT GOES INTO THE RESISTOR IS NOT BURNED UP. IF IT IS YOU WILL NEED TO CUT THE OLD PLUG END OFF AND INSTALL THE NEW PLUG END. THE CHEVY STORE WILL HAVE ALL THAT YOU NEED..PIECE OF CAKE.. IF YOU NEED MORE INFO PLEASE GET BACK TO ME ON THIS..WHEN YOU LEAVE THIS SITE WOULD YOU RATE MY ANSWER..THANK YOU,,, TOM >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
HI GAIL AGAIN, I HOPE I CAUGHT YOU IN TIME,I WAS ON MY LUNCH HOUR AND THOUGHT ABOUT YOUR QUESTION. I WANT TO REVISE PARTS OF IT...YOU ASKED IF THERE ARE ANY FUSES,,NO THERE ARE NOT.
HOWEVER DEPENDING WHAT YEAR THIS IS AND MODEL THERE IS ALSO A BLOWER MOTOR MODULE ALONG WITH THE RESISTOR..IF THERE IS NO LOWER SPEEDS AT ALL MORE THEN LIKELY THE MODULE IS THE PROBLEM AND NOT THE RESISTOR..THIS WILL BE ON SOME GM MODELS FROM 2002 UP TO PRESENT.SO FIND OUT IF YOUR CAR HAS A MODULE, THE CHEVY STORE WILL BEABLE TO TELL YOU THIS IN A SECOND..THIS MODUEL IS USUALLY LOCATED AROUND THE SAME AREA AS THE RESISTOR AND BLOWER MOTOR ITSELF,AS IN BEFORE.
SORRY FOR THIS LATE THOUGHT. TOM...
