2004 CHEVROLET TRAILBLAZER EXT Complaints

I STARTED TO LOSE THE HIGH SPEEDS ON THE FAN BLOWER. IN CHECKING THE INTERNET I FOUND THIS IS A COMMON PROBLEM FOR G.M. THE PROBLEM IS THE BLOWER MOTOR RESISTOR. WHEN I WENT TO REPLACE THIS PART I FOUND THAT THE WHOLE WIRING HARNESS HAD BEEN BURNT TO. IT GOT SO HOT THAT IT MELTED EVERYTHING. THE FUSE FOR THIS DID NOT EVEN BLOW. THIS COULD HAVE SET THE TRUCK ON FIRE. IT IS FUNNY HOW THE PARTS TO FIX THIS HAS MUCH THICKER WIRE. THE PARTS IN TOTAL WAS AROUND $118. THANKS TO A FRIEND I HAD NO LABOR COST. IF I WOULD OF TAKEN IT TO A G.M. DEALER FOR SURE THEY WOULD OF WANTED OVER $300. G.M. KNOWS THEY HAVE A PROBLEM AND ARE DOING NOTHING ABOUT IT. I FEEL THIS IS A SERIOUS MATTER AS IT COULD OF SET THE TRUCK ON FIRE. *TR

I HAVE MANY ELECTRICAL ISSUES WITH MY 04 TRAILBLAZER FROM MY WINDOW LIGHTS ON THE DRIVERS DOOR AND THE PASSENGER DOOR. I HAVE HAD MY RADIO REPLACED BECAUSE IT MELTED ONE OF MY CDS. MY HEAD LIGHTS WORK WHEN THEY FEEL LIKE IT SAME WITH THE REAR WIPER. IT HAS STALLED OUT IN TRAFFIC ON ME. I HAVE ALSO HEARD THAT IN MOST 2000 TO 2006 TRAILBLAZERS THE REASON FOR THE ELECTRICAL PROBLEMS IS BECAUSE WATER IS RUNNING DOWN THE PASSENGER SIDE DOOR INTO THE DASH AND HITTING ONE OF THE MAIN WIRING HARNESSES CAUSING IT TO HAVE MANY ELECTRICAL ISSUES. I HEARD THIS FROM SOMEONE WHO HAS AN 06 TRAILBLAZER THAT JUST HAD IT A REPLACED FOR $700.00 TO FIX AND WAS TOLD THAT IT WILL JUST HAVE TO BE REPLACED IN A FEW MORE YEARS BECAUSE THEY CANT FIX THE PROBLEM. *TR

SPEEDOMETER FREEZES AND YOU CAN'T TELL HOW FAST YOU ARE GOING. HAPPENS QUITE OFTEN. BROUGHT IT IN, BUT THEY WERE UNABLE TO DIAGNOSE THE PROBLEM AS IT WASN'T HAPPENING AT THE TIME. *TR

WE HAVE A 2004 CHEVY TRAILBLAZER, THAT ORIGINALLY BEGAN WITH THE SPEEDOMETER APPEARING TO BE STUCK FOR A FEW DAYS, WOULD GRADUALLY DECREASE. FOLLOWED BY THE RPM HAVING THE SAME PROBLEM. TODAY, 11/28/08, ALL GAUGES LIT UP, WARNING BELLS RANG, AND THEN THE ENTIRE INSTRUMENT PANEL SHUT DOWN. THERE WAS A RECALL FOR THE SILVERADO FOR THE SAME YEAR, BUT TRAILBLAZER OWNERS ARE REQUIRED TO PAY THE REPAIR BILL FOR A FAULTY INSTRUMENT PANEL. BEING UNABLE TO KNOW YOUR SPEED, HOW MUCH GAS YOU HAVE, OR IF YOUR RUNNING LOW ON VITAL FLUIDS SEEMS TO BE PRETTY DANGEROUS TO ME. THE FACT THAT GM WILL REPAIR THE SILVERADO, BUT NOT THE TRAILBLAZER DESPITE THE FACT THAT THEY ARE BOTH IN THE "TRUCK" CATEGORY IS RIDICULOUS. IT SEEMS TO ME THAT ANY ONE OF THESE PROBLEMS CAN LEAD TO DEATH OR INJURY OF THE OCCUPANTS OF MY VEHICLE, EITHER BY FIRE, STALLING IN TRAFFIC AND BEING HIT BY ANOTHER VEHICLE AT A HIGH RATE OF SPEED, OR BECAUSE OF THE INABILITY TO ENSURE THAT MY VEHICLE IS OPERATING WITH THE PROPER VITAL FLUIDS, AS WELL AS MAINTAINING A SAFE RATE OF SPEED. MY TEENAGE CHILDREN ALSO DRIVE THIS CAR ON OCCASION, AND THOUGH THEY'VE BEEN DRIVING FOR 3 & 4 YEARS, THEY DO NOT HAVE ENOUGH EXPERIENCE TO OPERATE THIS VEHICLE SAFELY. THERE WAS A RECALL FOR THE BRAKE LIGHTS, HOW CAN THEY JUSTIFY THAT WHEN PEOPLE ARE DRIVING AROUND WITHOUT PROPERLY WORKING INSTRUMENT PANELS? THE SOLUTION BEING OFFERED IS FOR THE CONSUMER TO PAY AT LEAST 500.00 TO REPAIR SOMETHING VITAL TO THE SAFE OPERATION OF THE VEHICLE, BUT GM WILL REPLACE THE TAILLIGHT/BRAKE LIGHT THAT COSTS PENNIES ON THE DOLLAR. *TR

THE SPEEDOMETER ON MY 2004 CHEVY TRAILBLAZER IS NOT WORKING PROPERLY. I NEVER KNOW WHAT SPEED I AM GOING. IT READS 120 MPH WHEN I AM AT A RED LIGHT! I'M CONSTANTLY IN FEAR OF BEING PULLED OVER BY POLICE WHETHER I'M IN THE CITY OR OUT IN THE COUNTRY BECAUSE I DON'T KNOW IF I'M FOLLOWING THE SPEED LIMIT. I TOOK IT TO THE DEALERSHIP AND THEY TOLD ME THE WHOLE DASHBOARD NEEDS TO BE REPLACED. THE PRICE OF THE PART IS @ $280 PLUS LABOR. SOME OF THE INTERIOR LIGHTS HAVE BURNT OUT AND LABELING OF KNOBS HAVE FADED. THE HUB CAPS ON THE 17" WHEELS AREN'T SECURE ENOUGH. THEY COME OFF EASY WHEN DRIVING THROUGH WATER. I LOST THEM DURING A STORM AND HAD TO REPLACE THEM WHEN I SAW THEY WERE MISSING. OF THESE, WHAT WORRIES ME THE MOST IS THE SPEEDOMETER AS IT IS IMPORTANT FOR SAFE DRIVING. *TR

SERVICE ENGINE SOON LIGHT CAME ON. TOOK IT TO AUTO ZONE AND COMPUTER DIAGNOSIS WAS EVAP EMISSION LEAK, SMALL. CODE:P0440. THIS HAPPENED TWICE OVER 2-3 WEEK PERIOD. REPLACED GAS CAP, THAT WAS NOT THE PROBLEM. LIGHT CAME BACK ON. TOOK TO DEALERSHIP GARAGE, I WAS TOLD THAT I HAD A SIGNIFICANT LEAK IN MY GAS TANK, AT THE FILLER NECK, WOULD COST $900 TO FIX IT. THING IS, I HAD BEEN DRIVING THIS CAR AROUND FOR OVER 3 WEEKS WITH MY 2 SMALL CHILDREN IN IT WITH THE POSSIBILITY IT COULD HAVE CAUGHT ON FIRE! HOW SCARY IS THAT? DEALERSHIP SAID IT WAS NOT SAFE TO DRIVE DUE TO POSSIBILITY OF CATCHING FIRE. CONTACTED GM CONSUMER SERVICE, AWAITING THEIR RETURN CALL. THEY DIDN'T SEEM INTERESTED IN HELPING ME. I KNOW PREVIOUS YRS (2002, 2003, AND EARLY 2004 MODELS) HAVE THE SAME PROBLEM AND WAS COVERED BY GM OR WERE RECALLED. I HAVE NEVER RECEIVED A RECALL NOTICE. I THINK IT IS SUSPICIOUS THAT I HAVE THE SAME PROBLEM AS PREVIOUS YR MODELS AND I HAVE ONLY 85,000 MILES ON MY CAR. *TR

THE DEALERSHIP THAT WE BOUGHT OUR CAR FROM DIDN'T WANT TO FIX OUR PROBLEM BEING THAT WE DIDN'T HAVE AND EXTRA 1500 DOLLARS TO BUY AN EXTRA WARRANTY FOR THE CAR ABOUT THREE WEEKS LATER AFTER TAKING IT OFF THE LOT AT A STORE THE CAR DIDN'T COME BACK ON SO WE CALLED AND ASKED A MECHANIC WHAT COULD BE WRONG AND THEY LET US KNOW THAT IT COULD BE THE FUEL PUMP OR SOME THING TO DO WITH THE FUEL LINES SO WE TOOK IT IN TO GET CHECKED AND IT WAS THE FUEL PUMP AND THE FUEL TANK SO WE CALLED THE DEALERSHIP AND TOLD THEM WHAT HAPPENED AND THEY TOLD US THAT THEY WOULD TALK TO THE MANAGER AND SEE WHAT THEY CAN DO SO THEN ABOUT TWO HOURS LATER THEY CALLED BACK SAYING THAT THEY COULDN'T DO NOTHING BECAUSE OF THE FACT THAT WE DIDN'T BUY THE EXTRA 1500 DOLLAR WARRANTY SO I TOLD THEM THAT IT WASN'T EVEN THIRTY DAY AFTER WE TOOK THE CAR OFF THE LOT AND ALL THEY COULD SAY IS THAT THEY WERE SORRY WE DIDN'T GET A (CAR FAX REPORT) LIKE IT SAYS ION A DISPLAY ON THE DEALERSHIP ENTRANCE DOOR WE DIDN'T GET NOTHING THEY EXPECTED US TO GIVE THEM 1500DOLLARS DOWN PAYMENT AND WE HAD TO USE THAT MONEY TO FIX THE CAR AND THEY DIDN'T EVEN CARE. *TR

I RECEIVED A NOTICE FROM CHEVROLET DATED OCTOBER 2008 REGARDING MY 2004 TRAILBLAZER EXT. THE NOTICE STATED A FUEL TANK MODULAR RESERVOIR ASSEMBLY MAY DEVELOP DUE TO CORROSION AND ALLOW FUEL TO LEAK. I WAS INFORMED THAT I MUST WAIT FOR THE CORROSION TO CAUSE A LEAK OF FUEL (AND RISK A FIRE HAZARD) FOR THE REPAIR TO BE COVERED. I WAS ALSO INSTRUCTED NOT TO TAKE MY VEHICLE TO MY CHEVROLET DEALER AS A RESULT OF THE NOTICE. I THINK THIS A PLAYING RUSSIAN ROULETTE WITH ALL OF THE OWNERS OF 2004 CHEVROLET TRAILBLAZERS. THIS IS UNFAIR AND DANGEROUS IN MY OPINION. I CALLED THE CHEVROLET CUSTOMER ASSISTANCE CENTER AT 899-630-2438. I WAS INFORMED I MUST COMPLY WITH THE NOTICE AND THAT IF I TOOK THE CAR IN TO THE DEALER, I WOULD BE CHARGED FOR THE SERVICE REVIEW OF THE PROBLEM. *TR

I OWN A 2004 CHEVROLET TRAILBLAZER EXT. THE GLASS PORTION OF THE TAILGATE BECAME UNGLUED FROM THE HINGE. THIS DID NOT ALLOW THE GLASS PORTION TO LATCH PROPERLY. THE DEALERSHIP/BODY SHOP SAID THEY HAD NEVER SEEN THAT HAPPEN. IN ALL THE OPENING TO INVESTIGATE THE PROBLEM, THE SUPPORT BAR FOR THE GLASS FAILED AND THE ENTIRE LIFTGATE COVER WAS LOOSE. MY THOUGHTS ARE THE COVER WAS THE START OF THE HINGE COMING UNGLUED AS THE BODY SHOP SAID THAT THEY HAVE HAD CASES WHERE THE COVER COMES FLYING OFF. THIS WOULD PLACE STRESS ON THE HINGE/GLUE AND CAUSE A FAILURE. THE BODY SHOP SAID THEY COULD NOT REPAIR. IT WOULD CAST $1000+ FOR A NEW GLASS AND $650+ FOR A USED GLASS. I TOOK IT TO A PRIVATE BODY SHOP AND THEY REGLUED THE GLASS AND HINGE BUT WERE UNABLE TO SECURE THE LIFTGATE COVER WITHOUT SCREWING IT IN PLACE. THE FIX LASTED FOR ABOUT A WEEK AND THEN WHEN I WENT TO LIFT THE TAILGATE (ENTIRE TAILGATE, NOT GLASS), IT BOUND UP ON THE TOP AND ONLY ONES 1/2 WAY. FINALLY, THE TAILGATE LATCH MALFUNCTIONED AND WOULD NOT LATCH WHEN TRYING TO CLOSE THE TAILGATE. UPON REPAIR, THE LATCH MECHANISM HAD DISINTEGRATED AND THE RUBBER COATING WAS ALL TORN APART, CAUSING THE LATCH MECHANISM TO JAM. *TR

I OWN A 2004 CHEVROLET TRAILBLAZER EXT. IN NOV 2007, THE SPEEDOMETER AND TACHOMETER STARTED ACTING ERRATICALLY. THE TACHOMETER WOULD SEEM TO STICK AND THE SPEEDOMETER WOULD REGISTER EITHER GROSSLY OVER OR UNDER MY CURRENT SPEED. IT STICKS WHEN TRYING TO ACCELERATE AFTER A DECELERATION. I HAVE BEEN ABLE TO GET IT TO RESET ONLY AFTER TURNING THE ENGINE ON OR OFF SEVERAL TIMES CONSECUTIVELY. I HAVE BEEN GOING DOWN THE INTERSTATE AT SPEEDS OF 70+ (WITHIN LEGAL SPEED) AND THE SPEEDOMETER WILL SHOW -5 MPH. ALSO, I HAVE BEEN GOING APPROX. 60MPH AND THE SPEEDOMETER SHOWS 90+MPH. I TOOK IT TO THE DEALERSHIP WHERE I PURCHASED IT IN NOV 2007 AND AT THE TIME, THEIR INSTRUMENTS COULDN'T DETECT A PROBLEM MILEAGE AT TIME OF FAILURE APPROX. 104,000 (HAD A 100,000 WARRANTY). THEY CHARGED A $100 DIAGNOSTIC FEE TO TELL ME THEY DIDN'T SEE A PROBLEM. CURRENT MILEAGE IS APPROX. 134,000. I HAVE NOT HAD THE PROBLEM FIXED. *TR
