2004 CHEVROLET TRAILBLAZER EXT Electrical System Problems

I OWN A 2004 CHEVROLET TRAILBLAZER EXT. TOOK THE VEHICLE IN OCTOBER 2009 FOR A OIL CHANGE & A EXHAUST LEAK WAS TOLD THE EXHAUST MANIFOLD NEEDED TO BE REPLACED, AFTER SEARCHING ON THE INTERNET FOUND OUT IT IS A KNOWN PROBLEM THAT GM WHEN MANUFACTURING THE VEHICLE USED BOLTS THAT WERE TO LONG MAKING THE MANIFOLD GET TO HOT AND THEREFORE LEADS TO IT CRACKING. AFTER HAVING THE VEHICLE REPAIRED AT THE COST OF $319.50 & HAVING IT BACK FOR A MONTH & DRIVING IT 3 TIMES MY SPEEDOMETER WENT HAYWIRE REGISTERING A SITTING STILL SPEED OF 45 MPH. ONCE AGAIN LOOKED ON THE INTERNET AND FOUND NUMEROUS COMPLAINTS ABOUT THE INSTRUMENT PANEL CLUSTER THEY HAVE ISSUED RECALLS FOR THE CHEVY TRUCKS AND YUKON GMC FOR THE SAME ISSUE BUT NO RECALL SO FAR ABOUT THE TRAILBLAZER. THIS REPAIR WILL COST ME $516.33, BOTH OF THESE REPAIRS ARE DUE...

I OWN A 2004 CHEVROLET TRAILBLAZER EXT. TOOK THE VEHICLE IN OCTOBER 2009 FOR A OIL CHANGE & A EXHAUST LEAK WAS TOLD THE EXHAUST MANIFOLD NEEDED TO BE REPLACED, AFTER SEARCHING ON THE INTERNET FOUND OUT IT IS A KNOWN PROBLEM THAT GM WHEN MANUFACTURING THE VEHICLE USED BOLTS THAT WERE TO LONG THEREFORE THE EXHAUST MANIFOLD WASN'T PROPERLY TORQUE/TIGHTENED WHICH MADE THE MANIFOLD VIBRATE UNTIL IT BROKE AND PRIOR TO ITS BREAKING IT LEAKED THE MANIFOLD BECOMES LOOSE AND THAT LEADS TO IT CRACKING. AFTER HAVING THE VEHICLE REPAIRED AT THE COST OF $319.50 & HAVING IT BACK FOR A MONTH & DRIVING IT 3 TIMES MY SPEEDOMETER WENT HAYWIRE REGISTERING A SITTING STILL SPEED OF 45 MPH. ONCE AGAIN LOOKED ON THE INTERNET AND FOUND NUMEROUS COMPLAINTS ABOUT THE INSTRUMENT PANEL CLUSTER THEY HAVE ISSUED RECALLS FOR THE CHEVY TRUCKS AND YUKON GMC FOR THE SAME ISSUE...

2004 CHEVROLET TRAILBLAZER SPEEDOMETER AND FUEL GAUGE ARE UNRELIABLE. SPEEDOMETER SOMETIMES SEEMS TO WORK BUT IS NO ACCURATE WHEN IT DOES SHOW A SPEED. FUEL GAUGE MOVES BUT IS USUALLY THE NEEDLE IS NOT EVEN IN THE NORMAL AREA IE. BETWEEN E AND F. THERE ARE NUMEROUS COMPLAINTS ONLINE, BUT GM HAS NOT ISSUED A RECALL. THIS IS A PREVALENT PROBLEM THAT GM SHOULD RESOLVE AT NO COST TO THE OWNERS. *TR

I HAVE A 2004 TRAILBLAZER I PURCHASED IN 2007 FOR MY WIFE. AFTER ABOUT A YEAR THE SPEEDOMETER IS NOT WORKING AT ALL. AFTER A LITTLE RESEARCH, HOW FOUND OUT MANY PEOPLE ARE HAVING THE SAME PROBLEM. I BELIEVE CHEVY SHOULD RECALL THE INSTRUMENT PANEL. *TR

WE ARE THE OWNER OF A 2004 CHEVY TRAILBLAZER. I WOULD LIKE TO FILE 4 MAJOR CONCERNS REGARDING OUR VEHICLE. THE FIRST I HAVE BROUGHT TO THE ATTENTION OF THE CHEVY COMPANY. OUR TRAILBLAZER WAS SHUTTING OFF DUE TO A BAD SEAL SOMEHOW CONNECTED WHEN THE HEAT/AIR IS RUNNING. THE VEHICLE JUST SHUTS OFF AND YOU LOSE COMPLETE CONTROL. WE HAD AN OUTSIDE MECHANIC FIX THE PROBLEM. THE SECOND IS THE LOSS OF OUR WINDSHIELD FRONT WINDSHIELD WIPERS. THEY NO LONGER WORK. THE 3RD IS THE REAR MOLDING BROKE LOOSE FROM WATER COLLECTING AND THEN FREEZING WITH NO WAY OF PREVENTING THIS FROM HAPPENING. WE LOST THIS PIECE OF MOLDING WHILE DRIVING ON THE HIGHWAY AND IT HIT A SEMI TRUCK. THE 4TH IS A MAJOR ELECTRICAL PROBLEM THAT HAS NOT BE ABLE TO BE DIAGNOSED. EACH MORNING WHEN STARTING THE VEHICLE, THE SUV WILL ACT LIKE THE BATTERY IS...

THE SPEEDOMETER HAS BEEN GIVING ME PROBLEMS FOR SOME TIME. AT FIRST IT WOULD MALFUNCTION FROM TIME TO TIME AT APPROXIMATELY 89,000. NOW THE SPEEDOMETER HAS STOPPED ALL TOGETHER. WHEN I STARTED INVESTIGATING THIS PROBLEM I FOUND OUT THAT CHEVROLET HAS ANOTHER VEHICLE, "CHEVY TAHOE", THAT HAS HAD THE SAME PROBLEM. WHY THERE IS A RECALL TO FIX THE TAHOE AND NOT THE TRAILBLAZERS? DEFINITE "DEFECT TREND" THAT SHOULD RESULT IN A RECALL. I DON'T HAVE THE $600+ TO FIX SO MUST CONTINUE TO DRIVE WITH MY YOUNG CHILDREN IN IT. A VERY UNSAFE SITUATION FOR ME AND THE OTHERS ON THE ROAD! WAITING FOR THE WHOLE INSTRUMENT PANEL TO FAIL AS OTHERS SAY HAPPENS NEXT! *TR

ON NOVEMBER 26 2007 TOOK MY CHEVY TRAILBLAZER 04 4 WHEEL DR. IN FOR STEERING WHEEL SHIMMY. COULD NOT DUPLICATE. ALSO C.D. CHANGER WILL NOT EJECT CD'S AND LOW BEAMS ON HEADLIGHTS NOT WORKING. REPAIRED HEADLIGHTS AND C.D. CHANGER. DID NOT FIX STEERING PROBLEM. ON JUNE 07 TOOK IN FOR MAJOR SERVICE WITH 33,000 MILES. ON DEC.8 2008 TOOK IN FOR STALLING WHEN COMING TO A STOP. COULD NOT DUPLICATE THE PROBLEM.THIS IS MY MAIN COMPLAINT, THE STALLING ON JAN.. 10 2009 TOOK IN FOR ERRATIC SPEEDOMETER WHICH WAS HAPPENING FOR ABOUT 3 MONTHS OFF AND ON.REBUILT THE SPEEDOMETER. ON JUNE 11 2009 TOOK CAR IN FOR STALLING, SES LAMP COMES ON WHEN DRIVING AND HVAC FAN DOES NOT BLOW ON THE #5 POSITION. THERE IS ALOT OF GRINDING AND WHINING WHEN VEHICLE SHIFTS TO SECOND GEAR. AND TURNING AT LOW SPEEDS THERE IS A WHINING COMING FROM THE FRONT...

THE SPEEDOMETER ON MY 2004 CHEVROLET TRAILBLAZER FREQUENTLY GETS STUCK OR STOPS WORKING, WHILE DRIVING. *TR

2004 CHEVROLET TRAILBLAZER ALL INSTRUMENTS INTERMITTENTLY QUIT FUNCTIONING DURING NORMAL OPERATION (SPEEDOMETER, FUEL LEVEL, RPM'S, BATTERY CHARGE, OIL PRESSURE, TEMPERATURE, MILEAGE, AND GEAR INDICATOR. YOU CAN'T TELL WHAT GEAR YOU ARE IN. DIFFICULT TO FIGURE OUT FORWARD FROM REVERSE. THIS IS NOT SAFE AT ALL TO OPERATE ESPECIALLY NOT KNOWING WHAT GEAR YOU ARE IN. *TR

INSTRUMENT CLUSTER MY 2004 CHEVY TRAILBLAZER HAS BEEN ACTING ERRATIC OR NOT AT ALL ON SOME OF THE GAUGES. I'VE READ THAT IT IS A VERY COMMON PROBLEM AND SOME HAVE BEEN RECALLED BUT NOT ALL. *TR

ON FEBRUARY 7, 2009, WE WERE DRIVING ON THE INTERSTATE. WHEN APPROACHING TRAFFIC I TOOK THE VEHICLE OFF OF CRUISE AND BEGAN TO SLOW DOWN. HOWEVER, THE SPEEDOMETER DID NOT MOVE. AFTER THAT, EVERYTIME I BEGAN TO ACCELERATE, THE SPEEDOMETER WOULD NOT MOVE. EVERYTIME I START THE CAR IT DROPS 5 MPH, BUT WHEN YOU USE CRUISE OR DO A CONSTANT SPEED, IT STICKS AGAIN. WE ARE GETTING READY TO GO ON A BIG FAMILY VACATION AND DO NOT FEEL SAFE TAKING MY FAMILY IN A VEHICLE THAT YOU DON'T KNOW HOW FAST YOU ARE GOING. MY MECHANIC IS REPLACING THE CLUSTER WITH A USED ONE FROM THE LOCAL SALVAGE YARD. A USED ONE WITH LABOR IS STILL GOING TO COST ME $200 AND WHO KNOWS HOW LONG THAT ONE WILL LAST. I CANNOT BELIEVE WITH THIS MANY COMPLAINTS ABOUT THE SAME EQUIPMENT FAILURE THAT GM HASN'T DONE ANYTHING. IT'S...

YESTERDAY MY DASHBOARD CONTROL PANEL WORKED GREAT. THIS MORNING (4/18/09) AS I WAS DRIVING TO MY BANK, I NOTICED THAT NONE OF THE GAUGES AND/OR LIGHTS WERE WORKING ( OIL GAUGE, TEMPERATURE GAUGE, BATTERY GAUGE, SPEEDOMETER, TACHOMETER, ETC). MAJOR SAFETY FACTOR. *TR

(SPEEDOMETER CLUSTER PROBLEMS) IT SEEMS TO BE A BIG PROB WITH CHEVY TRUCKS & SUVS. MY VEHICLE SPEEDOMETER CLUSTER IS NO WORKING, GM IS REFUSING TO RECALL THE 2004 TB. *TR

I HAVE A 2004 CHEVY TRAILBLAZER EXTENDED SUV. MY CHECK ENGINE LIGHT HAS CONTINUOUSLY FLASH ON AND OFF SINCE HAVING THE TRUCK ONLY SIX MONTHS. IT HAS CONTINUED TO DO THIS FOR THE LIFE OF THE CAR AT ALMOST 70,000 MILES. ALSO, MY SPEEDOMETER NOW WORKS ONLY WHEN IT WANTS TO. AT FIRST WE THOUGHT IT WAS BECAUSE OF THE COLD WEATHER, NOW IT IS ALMOST 70 DEGREES AND WE HAVE THE SAME PROBLEM. SOUNDS AS IF THIS IF VERY COMMON IN THESE MODELS. SOMEONE NEEDS TO FIND A WAY TO COMPENSATE OWNERS FOR THESE COSTLY REPAIRS. *TR

THE SPEEDOMETER HAS BEEN FAILING CONSISTENTLY. SEVERAL OCCASIONS IT FAILS TO RETURN TO ZERO, REGISTERING 100MPH WHEN GPS SHOWS 35MPH. AFTER SEVERAL DAYS, IT WILL START WORKING NORMALLY - THEN FAULT AGAIN. MILES DRIVEN ON THE ODOMETER DOES NOT APPEAR TO BE AFFECTED. THE CONDITION IS STARTING TO SPREAD TO OTHER GAUGES, WITH THE TACHOMETER SHOWING SEVERAL SIMILAR SYMPTOMS. *TR

TL*THE CONTACT OWNS A 2004 CHEVROLET TRAILBLAZER EXT. WHILE STOPPED AT A TRAFFIC LIGHT, THE CONTACT NOTICED THAT THE SPEEDOMETER DISPLAYED 50 MPH. THE SPEEDOMETER BECAME INOPERABLE AND WOULD OFTEN BECOME STUCK AT ZERO. IN ADDITION, THE SPEEDOMETER WOULD OFTEN DISPLAY 100 MPH WHEN THE CONTACT WAS DRIVING LESS THAN 50 MPH. THE MANUFACTURER AND DEALER COULD NOT PROVIDE ANY ASSISTANCE. THE FAILURE MILEAGE WAS 66,000 AND CURRENT MILEAGE WAS LESS THAN 73,000.

MY SPEEDOMETER ON MY 2004 TRAILBLAZER DOESN'T RECORD THE EXACT SPEED. *TR

THE GAUGES ON MY 2004 CHEVROLET TRAILBLAZER DO NOT WORK. I HAD THIS SAME PROBLEM SEVERAL MONTHS AGO AND TOOK TO DEALERSHIP TO FIX, THEY SAID THERE WAS NOTHING WRONG. NOW MY WARRANTY IS OUT AND THEY AGAIN ARE NOT WORKING. IT IS NOT SAFE TO DRIVE WHEN THE SPEEDOMETER, TACHOMETER, OIL GAUGE, AND TEMPERATURE GAUGES DON'T WORK. APPARENTLY THIS IS A PROBLEM THAT MANY OWNERS OF THE SAME MODEL HAVE REPORTED AND NOTHING HAS BEEN DONE ABOUT IT. THIS IS A SAFETY HAZZARD AND SHOULD HAVE A RECALL ASSOCIATED WITH IT WITH CHREVOLET FOOTING THE BILL. I GUESS IT WON'T BE ADDRESSED UNTIL DEATHS OR INJURIES ARE ASSOCIATED WITH IT. *TR

MY SPEEDOMETER AND TACH BEGAN READING HIGH (90MPH, 115MPH - 6000RPMS, 7000RPMS) BEFORE BOTH NEEDLES POINTED STRAIGHT DOWN. IF I TURNED OFF THE CAR, THEY WOULD RESET THEMSELVES TO 55MPH AND 5000RPMS. I WAS ON THE BEGINNING OF A LONG ROAD TRIP WHEN THIS HAPPENED, SO I WAS HOPING I WASN'T GOING TO GET PULLED OVER FOR SPEEDING. WHEN I RETURNED HOME I TOOK MY CAR IN TO BE REPAIRED AND THANKFULLY I WAS STILL UNDER WARRANTY. THIS PROBLEM ALSO HAPPENED TO MY PARENTS 2004 TRAILBLAZER. AFTER SEEING ALL OF THE COMPLAINTS OF THE SAME ISSUE, I FEEL THAT I SHOULDN'T HAVE HAD TO PAY MY $100 DEDUCTIBLE. THIS DEFINITELY SOUNDS LIKE A GM DEFECT. IF HIS ENDS UP BEING A RECALL, COULD I GET REIMBURSED?? *TR

WHILE EXITING MY CHILD SCHOOL PARKING LOT THE ENGINE SHUT DOWN AND WENT INTO LIMP MODE. I WAS IN THE MIDDLE OF A BUSY INTERSECTION, HAD TO TURN HAZARD LIGHTS ON SO I WASN'T HIT. COULD NOT GO OVER 5 MILES PER HOUR. SPEEDOMETER HAS INTERMITTENTLY GONE HAYWIRE. INSTRUMENT CLUSTER FAILURE. *TR

INSTRUMENT CLUSTER GOES CRAZY. NO OIL PRESSURE/EXCESSIVE OIL PRESSURE, NO TACH/PEGGED TACH, SPEEDOMETER GIVES FALSE SPEED READINGS(THIS IS REALLY DANGEROUS), BATTERY READS LOW VOLTS OR OFF THE SCALE VOLTS/. THIS HAPPENS EVERY DAY. CHEVY DEALERS ESTIMATED REPAIR COST $600-$700 DOLLARS. *TR

THE INSTRUMENT CLUSTER IS ERRATIC, SPEED SHOW ZERO, TACH IS NOT WORKING AT ALL NOW, THE OIL PRESSURE AND VOLT METER IS ERRATIC. THIS IS A UNSAFE DRIVING CONDITION NOT KNOWING IF YOU ARE GOING AT A UNSAFE SPEED OR IF YOU ARE DOING DAMAGE TO THE MOTOR WITH THE OIL PRESSURE IS SO ERRATIC. *TR

THE SPEEDOMETER HAS BECOME ERRATIC AND WILL NOT SHOW HOW FAST WE ARE DRIVING, CAUSING AN UNSAFE CONDITION. BASED ON THE NUMBER OF POSTS ON SEVERAL FORUMS, THIS APPEARS TO BE A VERY COMMON PROBLEM, AND WITH TIME MAY BECOME UNIVERSAL. *TR

THE ODOMETER AND RPM GAUGE STOP FUNCTIONING. WHILE YOU ARE DRIVING THE ODOMETER STOPS BELOW THE ZERO AND STAYS STUCK, IT WILL STOP AT 50 AND STAY THERE, IT WILL STOP ON 120 AND STAY THERE. THE ODOMETER GAUGE SOMETIMES WILL STOP BELOW THE 120 RIGHT ABOVE THE DIGITAL MILEAGE GAUGE. *TR

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

THE INSTRUMENT GAUGES, INCLUDING SPEEDOMETER ARE PRODUCING ERRATIC DATA, SOMETIMES 25-30 MPH FAST OR SLOW TO THE ACTUAL SPEED AS TRACKED BY A GARMIN GPS, AND MILEMARKER CALCULATIONS. THE OIL PRESSURE AND AMP GAUGES ARE NOT WORKING PROPERLY AS WELL. *TR

SPEEDOMETER STARTED TO ACT ERRATIC AT ABOUT 40K MILES. NOW AT 72K MILES, DOES NOT WORK AT ALL. I JUST SPENT $200 TRYING TO REPAIR, ONLY TO FIND OUT AFTER THAT FAILED, THAT THIS IS A COMMON PROBLEM WITH GM. HOW CAN THEY JUSTIFY RECALLING THE TAHOES, AVALANCHES, ETC, FOR THE SAME PROBLEM, BUT LEAVING THE TRAILBLAZERS OUT OF THIS SAFETY RECALL? *TR

NO PREVIOUS PROBLEMS WITH PANEL. PROBLEM OCCURS FREQUENTLY. TACHOMETER QUIT WORKING CORRECTLY...GOES COMPLETELY TO OPPOSITE END OF GAUGE. TOOK DAYS BEFORE IT WENT BACK TO NORMAL LOCATION. SPEEDOMETER DOES NOT WORK CORRECTLY...CONTINUES TO CLIMB TO HIGHER END OF GAUGE....READS ABOVE 30 EVEN WHEN STANDING STILL. GOES DOWN AFTER REPEATEDLY SHUTTING OFF AND RESTARTING ENGINE. WHIRRING SOUND MADE WHEN STARTING OR STOPPING ENGINE. CONTACTED CHEVY DEALER REPAIR SHOP, THEY ARE FULLY AWARE OF SITUATION, ADVISED IT WILL GET WORSE AND WILL EVENTUALLY STOP WORKING AT ALL. NO PARTS ARE SERVICEABLE, NEEDS TO BE SENT OUT FOR REPAIR, COULD TAKE ANYWHERE FROM A DAY TO A WEEK OR MORE DEPENDING ON THE PARTS NEEDED. PLUS THERE IS THE ADDITIONAL COST OF HAVING IT READ BY THE COMPUTER FOR THE CORRECT PART(S). MY CAR WILL BE INOPERABLE SOON ACCORDING TO DEALER, UNSAFE TO DRIVE, SITUATION NEEDS IMMEDIATE FIX. *TR

I OWN A 2004 CHEVROLET TRAILBLAZER NORTH FACE/EXT. THE SPEEDOMETER HAS BEEN GIVING ME PROBLEMS FOR SOME TIME. AT FIRST IT WOULD MALFUNCTION FROM TIME TO TIME. NOW THE FUEL GAUGE HAS STOPPED ALL TOGETHER. WHEN I STARTED INVESTIGATING THIS PROBLEM I FOUND OUT THAT IT IS A COMMON PROBLEM WITH THIS MAKE AND MODEL VEHICLE. I ALSO FOUND OUT THAT CHEVROLET HAS ANOTHER VEHICLE, "CHEVY TAHOE", THAT HAS HAD THE SAME PROBLEM. WHY THERE IS A RECALL TO FIX THE TAHOE AND NOT THE TRAILBLAZER EXT. IS VERY INTERESTING TO ME. I HAVE GONE AS FAR AS TO TAKE A LOOK AT THE TAHOE INSTRUMENT CLUSTER AND SAW THAT THEY ARE VERY ALIKE. THE VEHICLE RECALL TO REPLACE THE INSTRUMENT CLUSTER ON THESE VEHICLES SHOULD BE SENT OUT ASAP. IF YOU TAKE A LOOK AT THE COMPLAINTS ON THE INTERNET YOU WILL SEE THAT THIS IS A PROBLEM THAT...

WE WERE TRAVELING FOR THE HOLIDAYS AND NOTICED THAT THE RPM GAUGE STOPPED FUNCTIONING PROPERLY. IT WAS POINTING BELOW ZERO. THEN, LAST WEEK THE PROBLEM SPREAD TO THE GAS GAUGE AND THE OIL PRESSURE GAUGE. THIS IS A POTENTIAL SAFETY HAZARD. *TR

SEVERAL TIMES THAT I'VE BEEN DRIVING THE TRAILBLAZER, THE SPEEDOMETER GOES CRAZY AND SAYS THAT WE ARE TRAVELING AT A MUCH HIGHER RATE OF SPEED THAN WE ARE. LIKE IF IM GOING APPROX 70MPH, IT STATES WE ARE GOING ABOUT 110MPH! THIS IS DEFINITELY A SAFETY ISSUE! AND IT HAS NEVER BEEN A RECALL? *TR

I OWN A 2004 TRAILBLAZER EXT AND A COUPLE OF MONTHS AGO THE RPM GAUGE STOPPED FUNCTIONING AND DOESN'T EVEN REGISTER. LESS THAN A MONTH LATER THE SPEEDOMETER STARTED MALFUNCTIONING AND MANY TIMES DOESN'T EVEN REGISTER A SPEED WHILE DRIVING FOR SEVERAL HOURS. THIS HAS BEEN A DAILY OCCURRENCE EVERY TIME MY WIFE AND FAMILY GET IN THE VEHICLE. THIS IS A SERIOUS SAFETY HAZARD FOR MY FAMILY AND FOR ANYONE ELSE WE MAY PASS ON THE ROAD. I KNOW FROM READING MULTIPLE OTHER COMPLAINTS ACROSS THE INTERNET THAT THIS IS NOT AN ISOLATED ISSUE AND THAT GM HAS ALREADY RECALLED THE CONSOLE CLUSTER ON SEVERAL OTHER MODELS HAVING THE SAME OR SIMILAR ISSUES. WHEN ARE THEY GOING TO BE HELD RESPONSIBLE FOR ALSO RECALLING THE SAME PROBLEM ON THIS VEHICLE MAKE? *TR

SPEEDOMETER HAS COMPLETELY STOPPED WORKING. STARTED OUT INTERMITTENT. *TR

TOTAL FAILURE OF ENTIRE GAUGE CLUSTER AROUND 54000 MILES 600 DOLLAR REPAIR WAS TOLD THAT IT SHORTED OUT AND MELTED THE CONNECTORS. *TR

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

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,...

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

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....

AUTOMATIC TRANSMISSION SHIFTED OUT OF THIRD AND WOULD NOT SHIFT BACK WHILE I WAS ON THE FREEWAY. DEALER SAID A TRANSMISSION FLUSH AND FLUID CHANGE WOULD FIX IT. AFTER PERFORMING FLUSH DEALER TRANSMISSION WAS SHOT AND NEEDED REPLACEMENT. INSTRUMENT CLUSTER FUNCTIONING INTERMITTENTLY, SPEEDOMETER WORKS AT FIRST AND THEN SLOWLY GOES DOWN TO ZERO. *TR

RPM'S AND SPEEDOMETER TO NOT READ CORRECTLY. *TR

THE SPEEDOMETER ON MY 2004 TRAILBLAZER WORKS INTERMITTENTLY. THIS BEGAN IN THE FALL OF 2007. SOMETIMES IT WORKS SEEMINGLY FINE. IT WILL THEN FREEZE ON A SPEED. SOMETIMES IT WILL REGISTER A SPEED THAT IS OBVIOUSLY INCORRECT. FOR EXAMPLE IT WILL REGISTER A VARIABLE SPEED THAT IS 20 OR MORE MPH FASTER THAN WE ARE TRAVELING. IT SOMETIMES POINTS STRAIGHT DOWN. THEN LAST WEEK "OUT OF THE BLUE" IT WORKED AGAIN FOR A FEW DAYS. UNFORTUNATELY, THIS ONLY LASTED A FEW DAYS. I NEVER KNOW HOW FAST I AM GOING AND TRY TO STAY IN THE FLOW OF TRAFFIC. I ASKED THE DEALER ABOUT THIS AND THEY DID NOT MENTION ANY OTHER PROBLEMS WITH THIS AND TOLD ME IT WOULD COST $500 TO REPAIR. THIS IS A REAL SAFETY ISSUE. *TR

2004 CHEVY TRAILBLAZER. INTERMITTENT ENGINE STALLING SINCE NEW. MANY SERVICE VISITS TO CHEVY DEALERS TO FIX, HOWEVER MECHANICS STUMPED. LOCAL GAS STATION MECHANIC FOUND THE PROBLEM HAVING TO DO WITH COMPONENTS IN THE EMISSION CONTROL / VAPOR RECOVERY SYSTEM. NOW CHEVY NEEDS TO FIGURE OUT THE CURE. IN THE MEANTIME I GET TO DRIVE AROUND WITH THE "CHECK ENGINE" LIGHT ON. I GUESS THIS IS BETTER THAN BEING CRASHED BECAUSE MY CAR STALLED IN AN INTERSECTION OR ON THE HIGHWAY. CHEVY MECHANICS AND ENGINEERS NEED TO GET THE "DUH" AWARD. VERY BAD CUSTOMER SERVICE AND DIAGNOSTICS PERFORMED BY CHEVY. I WOULD STILL LIKE TO HAVE THE CHECK ENGINE LIGHT TO GO OFF, AND HAVE THE ENGINE NOT STALL IF THAT IS POSSIBLE. PLEASE SEND INFO TO HAVE THIS DONE IF POSSIBLE. *JB

I AM COMPLAINING ABOUT A 2004 CHEVY TRAILBLAZER PROBLEM THE SPEEDOMETER IS MEASURING INCORRECT SPEED OR NOT WORKING AT ALL. I CAN BE PARKED AND IT READS 60 MPH I AM DRIVING IT READS 120 MPH. IN SPEAKING WITH SEVERAL GM OWNERS THIS IS A PROBLEM WITH QUITE A FEW GM VEHICLES AND IS VERY DANGEROUS. I THINK THIS SHOULD BE LOOKED INTO BEFORE SOMEONE GETS HURT. IT IS VERY SCARY NOT TO KNOW WHAT SPEED YOU ARE DRIVING AT. IN SPEAKING TO SEVERAL OWNERS AND LOOKING AT WEB SITES OF COMPLAINTS THIS IS A PROBLEM AND HAS BEEN ONE FOR A LONG TIME. I DO NOT BLAME MY DEALER I BLAME CHEVROLET OR GM WHOEVER MADE THE CAR THERE ARE SO MANY COMPLAINTS ABOUT THIS SPEEDOMETER WITH OTHER MAKES FROM GM, ITS NOT THE DEALERS FAULT FOR THIS PROBLEM. *NM

ENGINE STALLS AT VARIOUS TIMES FOR NO REASON. HAVE HAD IT INTO DEALERSHIP MANY TIMES. DEALERSHIP HAS BEEN UNABLE TO ISOLATE PROBLEM. SERVICE ENGINE SOON LIGHT CAME ON AFTER FIRST STALL. DEALERSHIP RESET COMPUTER. SINCE THEN, THE ENGINE HAS STALLED AT LEAST 5 TIMES. SES LIGHT HAS NOT COME BACK ON. ENGINE USUALLY RESTARTS AFTER APPROX 5 MINUTES. *NM

FULL DESTRUCTION BECAUSE OF FIRE I WAS ON THE WAY BACK FROM A LONG TRIP IN SOUTHERN CHILE (UP TO USHUAIA) OVER THE "CARRETERA AUSTRAL" AND, AFTER ABOUT 9'000 KM DRIVE WITHOUT ANY PROBLEM, I SAW A WHITE SMOKE BACK MY VEHICLE. OIL PRESSURE: NORMAL, MOTOR TEMPERATURE: NORMAL. THIS MEANT IMMEDIATE STOP ALONG THE "RUTA 40 NORTE" IN ARGENTINA (ABOUT 100 KM NORTH OF BARILOCHE, ON THE WAY TO NEUQU). WHILE STOPPING, I FELT THE BRAKE PEDAL JUST GOING WITHOUT IMMEDIATE REACTION BUT THE PRESSION CAME BACK. WHILE BRINGING THE GEAR SHIFT TO POSITION PARKING, I DID NOT FEEL ANY SENSATION, AS IF IT WOULD HAVE NO CONNECTION; THE AUTOMATIC DOOR BLOCKER CONNECTED TO THE GEAR SHIFT DID NOT WORK TOO, SO THAT WE HAD TO UNLOCK THE DOORS MANUALLY. AFTER HAVING DISCONNECTED THE ENGINE, I SAW WHITE SMOKE COMING OUT FROM THE UPPER LEFT CORNER OF THE MOTOR. I...

THERE HAS NOT BEEN AN ACCIDENT YET, JUST ONE LOOKING FOR A PLACE TO HAPPEN. MY VEHICLE I BELIEVE HAS AN ELECTRICAL PROBLEM. WHICH IN TURN AFFECT ALL FUNCTIONS OF THE VEHICLE, SAFETY BEING ONE. I HAVE HAD (2) FAN SWITCHES GO BAD (2) CRANKSHAFT SENSORS GO BAD. (1) CRUISE CONTROL MALFUNCTION. (1) TURN SIGNAL RELAY (1) RADIO CONSOLE REPLACED FOR OVERHEATING (1) HEADLIGHTS WHEN BELOW 32 DEGREES FLUCUATE IN BRIGHTNESS TILL VEHICLE WARMS UP. DEALER STATED THIS IS NORMAL OPERATION. HA,HA, AND TRANSMISSION SHIFTING PROBLEMS (1)THEY REPROGRAMED COMPUTER TO SOLVE, NEXT SOME SOLINOID REPLACED AND NOW THE PROBLEM IS BACK. I HAVE A FAMILY OF 6 THAT I HAVE IN THE VEHICLE 90 % OF TIME. I NOW HAVE CONCERNS THAT THE WIRING MUST HAVE A SHORT SOMEWHERE. WHICH POTENTIALLY COULD CAUSE A FIRE, OR AN ACCIDENT DUE TO WHAT HAPPENS WHEN THE HEADLIGHTS GO OUT OR ANTILOCK BRAKE...
