2003 Chevrolet Trailblazer Ext Electrical Problems

ONE BY ONE THINGS HAVE BEEN GOING OUT AND NOT WORKING. FIRST THE CAR WOULD NOT START ALL THE TIME WITH THE KEY, THEN THE A/C STOPED WORKING, NEXT WAS THE FUEL PUMP, THEN THE INJECTORS. I CHECKED EVERYTHING IT COULD BE. I WAS DRIVING WITH MY KIDS DOWN THE HIGHWAY WHEN MY CAR JUST DIED LOST POWER STEERING SO IT WAS HARD TO GET OFF THE ROAD FAST. I GOT IT STARTED AND WAS DRIVING AND IT DID IT AGAIN. I WAS ABLE TO FINALLY GET IT HOME WHEN IT WOULD NOT START AGAIN. AFTER SOME RESEARCH ONLINE FOUND OUT THIS CAR HAS ISSUES WITH THE FUSE BOX ITSELF UNDER THE HOOD. I OPENED IT UP JUST TO FIND THE WORDING THAT CONNECTED THE PINS WAS BROKEN IN NUMEROUS PLACES AND HAD STARTED TO BURN UP IN THE BOX.

THE ELECTRONIC THROTTLE MODULE TO PCM COMMUNICATION ERROR COMES UP AND THE VEHICLE STARTS THE WARM UP PROCESS AND THEN DIES IN THE PROCESS OF WARM UP PROCEDURES. I GUESS MY QUESTION TO YOU IS HOW CAN I FIX THIS OR DOES A DEAL NEED TO FIX IT OR IS THERE A RECALL ON THIS ISSUE?

NONE OF MY GAGES WORK AND A LOT OF MY DASH LIGHTS ARE ON. I HAVE NO IDEA HOW MUCH GAS I HAVE. MY SPEEDOMETER AND RPM GAGES WORK BUT NOTHING ELSE DOES. THIS HAS BEEN HAPPENING ON AND OFF FOR ABOUT 3 MONTHS BUT THEY WOULD ALWAYS GO BACK ON. BUT NOW IT HAS BEEN OFF FOR A WEEK WITHOUT GOING BACK TO NORMAL. TWICE LAST WEEK THE RADIO AND THE POWER WINDOWS STOPPED WORKING AS WELL. THIS HAPPENS WHILE DRIVING PARKED ALL THE TIME AND IT DOESNT GO BACK TO NORMAL. I HAVE SEEN A LOT OF COMPLAINTS ABOUT THIS SO I HAVE NO CLUE WHY THERE ISN'T A RECALL. IT IS NOT SAFE TO DRIVE MY TRAILBLAZER UNTIL THESE THINGS ARE FIXED. I WORK AT A CHEVROLET DEALERSHIP AND THEY COULDN'T FIGURE OUT HOW TO FIX THIS EITHER. GM NEEDS TO PUT OUT A RECALL TO GET THIS FIXED ASAP.

THE GAS GAUGE STARTED MESSING UP/NOT READING RIGHT ESPECIALLY IN THE RAIN AND THEN SHORTLY AFTER THAT THE SPEEDOMETER STARTED DOING THE SAME THING. NOW NEITHER ONE WILL WORK AT ALL. THIS STARTED ABOUT TWO YEARS AGO AND QUIT WORKING ALL TOGETHER ABOUT 1 YEAR AGO. I HEARD THAT THIS IS HAPPENING TO ALOT OF TRAILBLAZERS. THIS STARTED WHILE THE VEHICLE WAS IN MOTION.

THE DRIVERS SEAT HEATER GOT VERY HOT AND THEN STOPPED WORKING SHORTLY AFTER. I DID AN INTERNET SEARCH AND FOUND THAT THIS IS VERY COMMON. I FOUND THAT ONE OF THE WIRES HAD OVERHEATED AND ACTUALLY BURNED THE FOAM AND COVERING. THERE ARE MANY COMPLAINTS AND PICTURES ON THE INTERNET. I REMOVED MY SEAT AND FOUND THE EXACT SAME PROBLEM. I AM ASTOUNDED THAT NOTHING IS BEING DONE TO STOP THE USE OF THESE DEFECTIVE HEATERS. THIS IS MOST CERTAINLY A VERY SERIOUS FIRE AND BURN HAZARD. *TR

MY VEHICLE STARTED RANDOMLY SHUTTING OFF WHILE DRIVING. LOSS OF POWER TO EVERYTHING BUT THE BRAKES. LUCKILY I WAS ONLY GOING 10-15MPH EACH TIME THIS HAPPENED. WITH THE RECENT RECALL IN GM VEHICLES REGARDING THE IGNITION SWITCH I THOUGHT IT WOULD BE A GOOD IDEA TO SWITCH THIS PART OUT FIRST. FIXED THE PROBLEM IMMEDIATELY. I WOULD LIKE TO BE REIMBURSED MY COST FOR PART AND LABOR. I CAN'T BELIEVE AS MANY KNOWN PROBLEMS THE TRAILBLAZER HAS WITH THIS THAT IT HAS YET TO BE ADDED TO THE RECALL LIST. *JS

WHEN I PULLED INTO DRIVEWAY, I PUT THE VEHICLE IN PARK, AND TURNED THE KEY OFF, AND ACTUALLY PULLED THE KEY OUT OF THE IGNITION SWITCH, WITH THE VEHICLE STILL RUNNING. I BACKED THE CAR UP, WITHOUT THE KEY IN THE IGNITION, WHERE I STARTED SMELLING WIRES BURNING. I CALLED FIRE DEPARTMENT, AND THEY PUT FIRE OUT ON THE FUSE BOX, WITH EVERYTHING MELTED AROUND IT. I HAVE HAD MINOR PROBLEMS WITH THE CAR, I.E. WHEEL BEARING AND BRAKES, BUT, NOTHING LIKE THIS. WHILE MY 14 YEAR OLD DAUGHTER AND I WERE IN THE CAR AT THE TIME, WE DID GET OUT, AND NO ONE WAS HURT. *TR

AFTER DRIVING THE VEHICLE LIKE NORMAL, STOPPED AT A GAS STATION AND WHEN IT WAS RESTARTED, THE FUEL GAUGE, OIL PRESSURE GAUGE, BATTERY GAUGE, TACHOMETER, PRETTY MUCH THE ENTIRE INSTRUMENT PANEL STOPPED WORKING THEN CAME BACK ON. ALSO, INSTEAD OF READING DRIVER LIKE IT NORMALLY DOES, THE PANEL WAS READING UNKNOWN DRIVER. THEN AS WE WERE DRIVING DOWN THE INTERSTATE HOME, THE SPEEDOMETER WENT TO 0 AND WOULD NOT COME BACK UP. AFTER WE GOT HOME, THE NEXT DAY THE PANEL WORKED FINE. THIS HAS OCCURRED NUMEROUS TIME SINCE THE FIRST INCIDENT IN 2011. I HAVE READ MULTIPLE FORUMS AND POSTS ONLINE FROM OTHERS STATING IT IS THE INSTRUMENT PANEL CLUSTER THAT MAY BE THE PROBLEM AND THERE WAS A RECALL ON OTHER CHEVY MAKES BUT NOT THE TRAILBLAZER. THIS IS A VERY SCARY PROBLEM AND SHOULD BE COVERED BY CHEVY DUE TO THE NUMEROUS OTHER TRAILBLAZER OWNERS WITH THE SAME ISSUE. *JB

STARTED THE CAR AND PULLED OUT OF MY DRIVEWAY WAS GOING 0-5 MPH AND THE SPEEDOMETER SHOT UP TO 40. STARTED DRIVING DOWN THE ROAD AND IT STAYED STUCK AT 40, BUT I WAS DOING 30MPH. PULLED INTO THE STORE 2 BLOCKS UP, SHUT THE CAR OFF. WHEN I TURNED IT BACK ON THE CAR WAS REGISTERING 13 MPH AT A DEAD STOP. WENT BACK HOME, CAR SAT OVERNIGHT. STARTED IT FOR WORK IN THE MORNING ON SUNDAY AND IT WAS IDLING AT 8 MPH. STARTED DRIVING TO WORK AND THE SPEEDOMETER WAS REGISTERING 60 MPH, YET I WAS GOING WITH THE FLOW OF TRAFFIC ON A CITY STREET THAT'S SPEED LIMIT WAS 45MPH. SEEMS I NEED TO KEEP TURNING OFF THE CAR AND TURNING IT BACK ON AGAIN IN ORDER FOR THE SPEEDOMETER TO RESET TO A LOWER NUMBER (I.E. 3 OR 8 MPH AT A DEAD STOP, VS. 13 TO 18 MPH AT A DEAD STOP). REVVED THE ENGINE TO SEE WHAT THE RESPONSE WOULD BE, TACHOMETER REGISTERED INCREASE, BUT THE SPEEDOMETER DID NOT BUDGE AT ALL! I WORRY THE DAY IT WILL SAY I AM DOING 40 BUT I AM ACTUALLY DOING 55 AROUND A CURVE. THE CAR IS ABSOLUTELY OFF LIMITS TO MY 17 YEAR OLD NOW. FUNNY THING IS I PREFERRED HER DRIVING THE TRAILBLAZER FOR SAFETY VS. HER LITTLE VW CONVERTIBLE. NOT ANY MORE!! I DO NOT SEE HOW CHEVY CLAIMS THIS IS NOT A SAFETY ISSUE! *TR

I AM A SENIOR CITIZEN I BROUGHT THIS CAR NEW. AFTER ONE YEAR I HAD TO REPLACE LINC PLATE. OVER THE YEARS EVERYTHING HAS GONE WRONG WITH THIS CAR. SPEEDOMETER HAS NOT WORKED SINCE AUG. '08, GAS GAUGE STOPPED OCT. '11. INSTRUMENT CLUSTER SINCE 2010 AND GM KNOWS THIS IS A DEFECTED PART. YET GM PAID FOR THIS SAME DEFECTED PART AT THEIR COST FOR THE TAHOE, BUT HAS NOT PAID FOR THE TRAILBLAZER. WHY? WINDOWS AND DOORS DO NOT UNLOCK ON COMMAND. WINDOW WIPER(REAR) STOPPED WORKING-I REPLACED THAT PART. A/C COMES ON MY ITSELF. THERMOSTAT FAILURE. I THINK GM SHOULD STAND BEHIND THEIR PRODUCT. THE ONLY REASON THEY WOULD NOT IS THAT THEY ALREADY KNOW THAT THEY ARE PRODUCING SUBSTANDARD PRODUCTS THAT ARE NOT FIT TO BE DRIVEN ON THE ROAD. *TR

THE GAUGES STARTED FAILING ONE AT A TIME. FIRST THE OIL AND BATTERY NEEDLES MOVED TO THE FAR RIGHT AND BURIED OFF THE CHART. NOW THE SPEED IS READING 90MPH AT A STOP LIGHT AND 10MPH ON THE INTERSTATE. THE CLUSTER IS GONE AND THE WHOLE DRIVER DASHBOARD IS FAILING. THE GAS AND OIL GAGUES I FEAR ARE NEXT. ACCORDING TO DEALER THEY KNOW THERE IS A PROBLEM, BUT THEY HAVE NO PROBLEM CHARGING UP TO $600 TO FIX THE SITUATION. THIS IS MECHANICAL AND NOT CAUSED BY THE OWNER. THERE ARE BLOGS ALL OVER THE PLACE ON THE SAME PROBLEM. *TR
