2005 GMC Canyon

THIS VEHICLE USES A RESISTOR FOR VARIABLE SPEEDS (X4) ON THE VENTILATION BLOWER. DURING CONTINUOUS OR FREQUENT USE (I.E. DEFROST, AIR CONDITIONING) A BURNING SMELL DEVELOPS. THE BURNING SMELL INCREASES OVER TIME AFTER REPEATED USAGE AND THE INCREMENTAL BLOWER SPEED CIRCUITS ARE BURNED OUT AND DISABLED. THE WIRES ARE BLACKENED AND CONNECTORS MELTED AND THE PLASTIC CONNECTING BASE OF THE RESISTOR IS MELTED AND BLACKENED. AT TIMES THE VEHICLE WIRE HARNESS IS AFFECTED. GM HAS A "SERVICE BULLETIN" WHICH PRESCRIBES A "REPAIR" FOR THIS MALFUNCTION (I.E. NEW RESISTOR, PIGTAIL WIRES AND CONNECTORS, AND A BLOWER REPLACEMENT IF REQUIRED) ---- BUT IT DOES NOT FIX THE PROBLEM AND IT OCCURS REPEATEDLY THROUGHOUT OWNERSHIP OF THE VEHICLE. WE HAD TO REPLACE THE RESISTOR AND WIRES IN THIS CIRCUIT AT LEAST 6 TIMES IN THE LAST THREE YEARS. OUR CANYON BEGAN EXPERIENCING THIS PROBLEM AT ABOUT 85,000 MILES. EACH REPLACEMENT (INCLUDING LABOR AND PARTS) COSTS ABOUT $150. I CONTACTED GM LAST YEAR -- THEY GAVE ME A CASE NUMBER BUT WANTED ME TO PAY OUT OF POCKET BY THE HOUR FOR ELECTRICAL TROUBLESHOOTING. I ALSO CONTACTED CORPORATE CUSTOMER SERVICE LAST MONTH WHEN THEY WERE ADVERTISING NEW RECALLS BASED ON SERVICE BULLETINS --- BUT THEY WERE NOT INTERESTED UNLESS AN OPEN FLAME WAS PRESENT IN THE SITUATION. WE EVENTUALLY BYPASSED THIS CIRCUIT BY INSTALLING CORE WIRE, A ONE-WAY SWITCH, AND A FUSE. AT THE VERY LEAST, THIS IS A DISTRACTION. AT THE WORST -- DEFROST, HEAT, A/C, ALL FUNCTIONS INVOLVING THE BLOWER BECOME DISABLED AND THE VEHICLE HARNESS CORE WIRE CAN BECOME DAMAGED. *TR

DRIVER SIDE SUN VISOR FAILURE. VISOR LOOSENS AND DROPS TO COVER VISUAL FIELD IN FRONT OF DRIVER; VISOR FALLS OFF WHILE VEHICLE IN OPERATION CREATING HAZARD BY LANDING ON STEERING WHEEL, ARM, FACE OF DRIVER. I HAVE OWNED 3 GM VEHICLES WITH THE SAME PART THAT FAILS IN THE SAME WAY. PRESENT VEHICLE: PART WAS REPLACED AND THE NEW VISOR FAILED IN THE SAME WAY. GM REFUSES TO ACKNOWLEDGE THIS AS A REPEAT PROBLEM OF THE SAME PART, BUT IT IS. I AM ORIGINAL OWNER ON 2 AND SECOND OWNER ON THE THIRD OF THESE VEHICLES. I HAVE NOT GONE IN YET AND HAVE THE PART; THIS IS A SAFETY ISSUE AND NEEDS TO BE ADDRESSED. GM ISN'T ADDRESSING IT. PRESENT VEHICLE: 2005 GMC CANYON; PRIOR WERE GMC SAFARI AND PONTIAC GRAND AM. ALL THREE HAD THE SAME VISOR DESIGN AND POINTS OF FAILURE. ALL FAILURES OCCURRED WHILE DRIVING AND CREATED SAFETY HAZARD WITHOUT CAUSING ACCIDENTS, THOUGH HIGH POTENTIAL FOR IT. *TR

AIR CONDITIONING FAN ABRUPTLY STOPPED WORKING ON ALL FAN SPEEDS EXCEPT "4", THE HIGHEST POSITION. CHECKED INTERNET FOR POSSIBLE SOLUTIONS AND FOUND THAT THERE HAVE BEEN NUMEROUS FAILURES EXACTLY LIKE MINE. ALL INVOLVED THE "BLOWER MOTOR RESISTOR ASSEMBLY, CONNECTOR AND/OR WIRING HARNESS" SHORTING OUT. SCORTCHING THE CONNECTORS, RESISTOR ASSEMBLY AND CAUSING THE PLASTIC TO MELT/BURN. GM PARTS AT LOCAL DEALERSHIP HAD REPLACEMENT PARTS AND I WAS ABLE TO RESOLVE THE PROBLEM. SPEAKING A GM SERVICE ADVISOR, HE CONFIRMED THAT THERE ARE NUMEROUS REPAIR PROBLEMS WITH THESE PARTS ON THE GMC CANYON/ CHEVROLET COLORADO 2004-2007. BUT NO EXPLANATION FOR WHY THEY ARE FAILING. NUMEROUS INTERNET REPORTS WITH PHOTO'S SHOWING DAMAGE AND EXPLAINING PROBLEM MOST REQUIRING MULTIPLE OR REPEATED REPAIRS. OLD PARTS ARE AVAILABLE. *TR

REAR VIEW MIRROR SIGHT LINE IS SEVERELY RESTRICTED TO A SMALL CENTERED TUNNEL LIKE AREA. *TS THE CONSUMER STATED, WHEN THE REAR BENCH IS FOLDED DOWN, THE HEAD REST MAKES CONTACT WITH THE DRIVERS SEAT, WHICH DOES NOT CREATE A FLAT PLATFORM AS DESIGNED. MOVING THE FRONT SEAT FORWARD TO ACCOMMODATE THE REAR FOLDING SEAT, COMPRISES THE DRIVERS POSITION BY MAKING IT EXTREMELY UNCOMFORTABLE AND CRAMPED. CONSEQUENTLY, THE FEATURE DOESN'T WORK. THERE WAS NOTHING IN THE MANUAL STATING THERE WAS AN OPTION TO REMOVE THE HEAD RESTS. THE CONSUMER WAS NOT GETTING THE CORRECT MPG. AT NIGHT, WHEN THE CLOCK AND RADIO DASH LIGHTS ARE ON, THE BLUE/GREEN HORIZONTAL DISPLAY LIGHT REFLECT TO THE REAR WINDOW. THE IMAGE IS THEN REFLECTED INTO THE REAR VIEW MIRROR AS A VERTICAL BLUE/GREEN LINE. *JB
