I CURRENTLY OWN A 2005 CHEVY TRAILBLAZER. OVER THE PAST YEAR I HAVE A VARIETY ELECTRICAL PROBLEMS WITH MY BLAZER. IN THE JANUARY OF 2010 I HAD TO REPLACED BY AC / HEATER AS IT SIMPLY WENT OUT. WHEN THE VEHICLE WAS FIXED A CERTIFIED MECHANIC HE SHOWED US THE WIRING HARNESS THAT HAD SIMPLY MALFUNCTIONED AND MELTED ALL OF THE WIRES TOGETHER. NOW IN THE PAST THREE MONTHS MY GAS GAUGE HAS STOPPED WORKI…
THE SPEEDOMETER IN MY 2005 CHEVY TRAILBLAZER HAS BROKEN AND I ONLY HAVE 45,000 MILES ON MY VEHICLE. I HEARD ABOUT A RECALL OR GETTING ASSISTANCE FROM GM TO REPLACE BUT LEARNED IT IS ONLY FOR TAHOE'S, SUBURBAN'S AND TRUCKS. I DON'T FEEL THAT IS FAIR THEY WON'T HELP ME AND THAT A SPEEDOMETER SHOULD NOT WEAR OUT THAT QUICKLY. REPLACEMENT COST CAN BE $600 - $800. *TR
THE HEADLIGHTS/DASH LIGHTS STARTED FLICKERING. THE BATTERY VOLTAGE METER WAS JUMPING BACK AND FORTH. THE HEADLIGHTS WOULD GO OUT AND THEN COME BACK ON. I WAS NOT ABLE TO DUPLICATE THIS PROBLEM. THERE WERE NO CODES STORED IN THE COMPUTER FROM THE INCIDENT. IT HAS HAPPENED SINCE 11/23/05 AT LEAST TWICE. *JB
FOR SEVERAL YEARS THE LOW BEAM HEADLIGHTS WOULD GO OFF AND ON INTERMITTENTLY. NOW, THEY ARE MOSTLY OFF WHICH MEANS I CANNOT DRIVE MY VEHICLE AT NIGHT ANYMORE UNLESS I WANT TO BLIND PEOPLE OR GET STOPPED. I HAVE CHANGED HEADLAMPS, RELAYS AND FUSES TO NO AVAIL. NOW, I SEE THAT MANY OTHERS WITH THE SAME MAKE AND MODEL SUV HAVE BEEN HAVING THE SAME ISSUE BUT NO RECALLS HAVE BEEN ISSUED FOR THIS YEAR M…

SUDDEN SPEEDOMETER FAILURE. *TR
MY HEADLIGHTS AND DASH LIGHTS FLICKER WHILE DRIVING. ALSO WHILE DRIVING MY LIGHTS WILL DIM AND THE BLOWER FOR HEAT & A/C WILL SLOW AND THEN PICK UP TO NORMAL SPEED AGAIN. IT ALSO REVS BY ITSELF, EVEN IN PARK AND WILL GO FORWARD SLIGHTLY WHEN IT DOES SURGE. THESE PROBLEMS ONLY STARTED AFTER THE ALTERNATOR WAS REPLACED. I THINK IT IS A SAFETY HAZARD TO HAVE LIGHTS FLICKERING AND ENGINE SURGES. *…
TL*THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. WHILE DRIVING APPROXIMATELY 5 MPH, THE CONTACT NOTICED THAT THE SPEEDOMETER DID NOT INDICATE THE CORRECT SPEED. OTHER COMPONENTS ON THE INSTRUMENT CLUSTER WERE ALSO NOT FUNCTIONING PROPERLY. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHO STATED THAT THE INSTRUMENT CLUSTER NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED BUT THE PROBLEM OCCURRED A…
