2005 Chevrolet Trailblazer

THE HEADLIGHTS ON THE VEHCLE DIMME D INTERMITANTLY. IT OCCURRED AT NIGHT AND OFTEN WHEN I REMOVE THE FOOT FROM THE GAS PEDAL. IT MAY HAPPEN ONE NIGHT AND NOT HAPPEN AGAIN UNTIL 3 TO 4 NIGHTS FROM THEN. *AK IT HAS BEEN BROUGHT BACK TO THE MULTIPLE DEALERSHIPS 4 TIMES. ONCE, THEY STATED IT WAS A BAD GROUND, NEXT TIME THEY CHANGED THE BATTERY AND THE NEXT TIME THEY SAID IT WAS NORMAL. THEN I WENT TO ANOTHER DEALERSHIP AND THEY CHANGED OUT THE ALTERNATOR. THIS IS A SAFETY ISSUE FOR OTHER DRIVERS ALNG WITH MYSELF BECAUSE OF THE BLINKING HEADLIGHTS. THE AMP METER OF THE DASHBOARD FLUCTUATES WHEN THIS OCCURS.

IN MARCH 2007 THE CHECK ENGINE LIGHT CAME ON AND STAYED ON . I TOOK VEHICLE TO DEALER TO HAVE IT CHECKED OUT. IT TURNED OUT TO BE THE SECONDARY AIR PUMP EITHER CLOGGED, NOT RUNNING OR SOMETHING ELECTRICAL WITH IT. EVER SINCE THEN ALL THE EXTERIOR AND INTERIOR LIGHTS BECAME BRIGHT THEN DIMMED FOR A FEW MINUTES WHEN I START THE VEHICLE. AFTER LEAVING FOR WORK AND STOPPING THE VEHICLE TO TURN, AND THEN AGAIN A FEW MILES DOWN THE ROAD, THE HEADLAMPS STARTED TO FLICKER. SOMETIMES IT FLICKERED A FEW MORE TIMES BEFORE I GOT TO WORK , ONLY 25 MINUTES FROM HOME. I HAVE NOTICED THE BATTERY GAUGE FLUCTUATED WHILE THIS IS HAPPENED. I WAS TOLD THAT THIS WAS NORMAL. ALSO, I AM NOT SURE THIS WAS RELATED, BUT EVER SINCE THE CHECK ENGINE"LIGHT PROBLEM THE AIR CONDITIONING SYSTEM DID NOT WORK PROPERLY. IT DIDN'T WORK ON 5, BUT IT DID BLOW SOME ON THE OTHER LEVELS, AND THAT VARIED TOO. I HAVE HAD THE AIR CONDITIONING RECHARGED, TO NO AVAIL, IT ACTED LIKE THERE WAS A LEAK SOMEWHERE. HOPEFULLY ,GM OR SOMEONE ELSE WILL FIND THE SOLUTION BEFORE THERE WAS AN ELECTRICAL FIRE OR EVEN A CASE OF ROAD RAGE DUE TO OTHER DRIVERS THINKING I WA S FLASHING THE BRIGHT LIGHTS AT THEM. *AK

2005 CHEVROLET TRAILBLAZER HEADLIGHTS DIMMED WHILE DRIVING FOR NO REASON. VEHICLE BROUGHT TO DEALER, THEY STATED IT WAS NORMAL DUE TO AN AIR PUMP TURNING ON AND OFF. I FELT IT WAS VERY DANGEROUS DUE TO OTHER DRIVER'S THINKING I AM FLASHING THE HEADLIGHTS AT THEM. THAT HAPPENED ABOUT 10 TIMES A WEEK WHILE DRIVING AT NIGHT. I HAVE FOUND ONLINE MANY OTHER OWNERS WITH THE SAME PROBLEM. AT THE LINK BELOW HTTP://WWW.TOPIX.NET/FORUM/AUTOS/CHEVROLET-TRAILBLAZER/TUCLLQK4UIF5NA0UT. AK

THE HEADLIGHTS WILL DIM WHEN DRIVING THE VEHICLE. THIS CAN OCCUR WHEN IDLING BUT MOSTLY HAPPENS WHEN THE VEHICLE IS AT HIGHWAY SPEED. THIS HAS HAPPENED SEVERAL TIMES AND TWO DIFFERENT DEALERS HAVE CHECKED THE PROBLEM AND PERFORMED ALL APPLICABLE TSBS AND REPLACED THE BCM WITH NO DIFFERENCE IN THE PROBLEM. THE LIGHTS WILL DIM ENOUGH THAT WHEN DRIVING ON DARK COUNTRY ROADS I AM NOT ABLE TO IDENTIFY THE EDGES OF THE ROAD. TECH SUPPORT CLAIMS THIS IS NORMAL OPERATION OF THE SYSTEM. *JB

2005 CHEVROLET TRAILBLAZER'S HEADLIGHTS FLICKERED ON AND OFF. **CC SOMETIMES THE FLICKERING LAST FOR A FEW SECONDS OTHER TIMES IT HAS LASTED UP TO 10 MIN. THE DEALER WAS ABLE TO DUPLICATE THE PROBLEM BUT STATED THERE WAS A TSB FROM CHEVROLET WHICH STATED THE FLICKERING WAS NORMAL. THEREFORE THERE WERE NO REPAIRS ATTEMPTED. THE BRAKES PULSATED DUE TO RUST ON THE ROTORS. *NM

2005 CHEVROLET TRAILBLAZER - VEHICLE HEADLIGHTS INTERMITTENTLY FLICKER WHILE OPERATING. CONDITION EXISTS EVERY TIME THE VEHICLE IS OPERATED RESULTING IN A SAFETY HAZARD TO BOTH THE DRIVER, OCCUPANTS AND OTHER MOTORISTS. CHEVROLET REPRESENTATIVES HAVE REPLACED THE ALTERNATOR/GENERATOR, AIR PUMP AND FIXED A POTENTIAL ELECTRICAL GROUND WITH NEGATIVE RESULTS. AT THIS POINT CHEVROLET REPRESENTATIVES ARE STATING THAT THIS ISSUE CAN NOT BE FIXED AND SHOULD BE ACCEPTED AS A NORMAL DRIVING CHARACTERISTIC OF THE VEHICLE. THIS IS A SAFETY CONCERN. *JB

NIGHT DRIVING UNDER NORMAL CIRCUMSTANCES THE VEHICLE A CHEVROLET TRAILBLZER LS 2005 HAS A PROBLEM THAT RANDOMLY SHUTS OFF THE HEADLIGHTS AND DASHBOARD LIGHTS. THE TRAILBLAZER DECIDES TO DO THIS TOTALLY ON ITS OWN AT RANDOM. THIS CAUSES A POTENTIALLY DEADLY SITUATION WHEN ON THE INTERSTATE AND YOUR HEADLIGHTS GO OUT AND DECIDE TO COME BACK ON AT RANDOM INTERVALS MAYBE APROXIMATELY 15 TO 20 SECONDS APART. SEVERAL ATTEMPS HAVE BEEN MADE TO THE CHEVROLET DEALERSHIP TO GET THE PROBLEM REPAIRED. THEIR COMMENT IS THAT THEY EITHER CANNOT DUPLICATE THE PROBLEM OR THEIR IS A SERVICE BULLETIN THAT EXPLAINS THE ISSUE. I HAVE DONE THE PROCEDURES THAT THE DEALERSHIP DESCRIBED IN THE SERVICE BULLETINS WITH NO SUCCESS. CURRENTLY MY TRAILBLAZER IS BEING REPAIRED ONCE AGAIN AT TERRY LEE CHEVROLET AS OF 12-19-06. THE LAST TIME THAT THE VEHICLE WAS IN FOR REPAIR TERRY LEE CHEVROLET REPLACED WHAT THEY HAD THOUGH WAS A FAULTY BODY CONTROL MODULE. REPLACING THIS MODULE OBVIOUSLY DID NOT RECTIFY THE PROBLEM AND ON THURSDAY 12-14-06 THE PROBLEM ONCE AGAIN RETURNED. SINCE THE VEHICLE IS USED TO TRANSPORT MY CHILDEREN AND WIFE WHO HAVE BEEN DRIVING PRIMARILY AT NIGHT. I HAVE BECOME SKEPTICAL ABOUT WHETHER OR NOT THE VEHICLE IS SAFE TO ACTUALLY DRIVE AT NIGHT BECAUSE YOU NEVER KNOW WHEN THE LIGHTS WILL DECIDE TO TURN OFF BY THEMSELVES AND POTENTIALLY CAUSE THEM TO BE IN AN ACCIDENT. *NM
