2005 Chevrolet Colorado Electrical Problems

Your airbag warning light stays on, leaving you uncertain whether your airbags will work properly in a crash or deploy unexpectedly. The problem is caused by wires in the back door jamb that become worn and break, which disables the airbag system. This issue also causes your vehicle to fail inspection in Massachusetts.

Your taillights don't turn on when you switch on your headlights at night, which makes your vehicle less visible to other drivers behind you. Since the fuses and bulbs test fine when checked separately, the problem likely lies in the wiring or electrical connections to the taillight assembly.

Your truck's ignition switch is triggering the anti-theft system, preventing the engine from starting. You have to wait about 10 minutes before it will start again. Multiple mechanics have indicated this is a known defect covered under a recall, and the dealer is the only place authorized to repair it.

Your heater and fan motor only work on the highest speed setting and won't respond to lower speed settings. You've had a garage attempt repairs three times without success. The issue likely involves the blower motor speed control system, which may need replacement or rewiring.

WIRING FOR TURNSIGNALS MELTS DOWN. THERE IS A WIRE HARNESS WITH A CONNECTOR AT THE TURN FRONT SIGNALS, THE WIRE GAUGE IS IN ADEQAUTE AND CAUSEA EXCESSIVE HEAT BUILD-UP THIS CAUSES THE WIRES AND CONNECTORS TO THE FRONT TURN SIGNALS TO MELT DOWN AND THE TURN SIGNALS BECOME INOPERABLE. I HAVE REPLACED THESE COMPONENTS TWICE DUE TO THIA ISSUE. THE RESISTOR PACK FOR AIR CONDITIONING BLOWER FAN SPEED CONTROL MELTS AND CATCHES FIRE. I HAVE REPLACED THIS PART TWICE AND ULTIMATELY HAVE BYPASSED THE RESISTOR PACK LEAVING THE AC BLOWER WITH ONLY THE CHOICE OF HIGH SPEED OR OFF.

I AM EXPERIENCING AN INTERMITTENT ISSUE WHERE THE PASSLOCK SYSTEM FAILS WHEN ATTEMPTING TO START THE VEHICLE AND I HAVE TO WAIT 15 MINUTES FOR IT TO TIME OUT. THERE ARE FORUMS WITH THIS MODEL OF TRUCK THAT STATE THIS IS A COMMON PROBLEM BUT I HAVE FOUND NO RECALL ON IT. I HAVE FOUND THAT THE IGNITION AND BODY CONTROL MODULES WERE TO BLAME AND CURRENTLY DEALERS ARE CHARGING UPWARD OF $1100 TO REPAIR. THIS SHOULD BE A RECALL ISSUE DUE TO THE WIDESPREAD PROBLEM AND THAT IT IS A KNOWN DEFECT SPECIFIC TO THIS MODEL OF TRUCK.

HELLO, I JUST PURCHASED A USED VEHICLE AND IT HAS THE SAME PASSCODE PROBLEM THAT MY 2000 EXPRESS VAN HAS. THIS IS A SUBSTANTIAL PROBLEM AND GM IS NOT OWNING UP TO THE PROBLEM AND SHOULD HAVE A FIX FOR IT. HOW LONG ARE YOU GOING TO IGNORE THAT ''TIS IS A SERIOUS PROBLEM AND IN AN EMERGENCY SITUATION HAVING TO WAIT 10 MIN. COULD BE LIFE THREATENING. ALL I WANT IS THE 05 COLORADO TO WORK, I'LL BE SELLING THE VAN AND PASSING THE PROBLEM TO SOMEONE ELSE. TIME TO STAND BEHIND YOUR VEHICLES, THIS WILL BE MY LAST GM VEHICLE IF YOU WON'T FIX IT. AFTER 30 YEARS OF LOYALTY YOU SHOULD HAVE MY BACK

MY CRUISE CONTROL STOPPED WORKING AND THEN MY BREAK LIGHTS. PUT IN NEW BREAK BULBS AND THEY STILL DO NOT WORK! I WAS DRI ING WHEN CRUISE CONTROL WENT OUT AND MY HUSBAND NOTICED MY BREAKS WHILE I WAS DRIVING.

AT DIFFERENT TIMES TURN SIGNALS, BRIGHTS, BRAKE LIGHTS WILL QUIT WORKING AND DASH LIGHT INDICATOR THAT AIR BAG IS NOT WORKING WILL ILLUMINATE. THIS CAN HAPPEN WHILE DRIVING OR WHEN FIRST STARTING UP. AT TIMES YOU CAN PUSH STALK UP FOR A RIGHT HAND TURN AND LEFT TURN SIGNAL INDICATOR WILL LIGHT UP AND BLINK. IF YOU PUSH THE STALK DOWN FOR A LEFT TURN SIGNAL NOTHING WILL HAPPEN.

THE BLOWER MOTOR RESISTOR AND THE WIRING IS BROKEN FOR THE THIRD TIME. THIS TIME THERE WERE BURN MARKS ON THE WIRES WHICH WORRIES ME ABOUT A POSSIBLE FIRE IN MY DASHBOARD. THIS OCCURS WHILE THE VEHICLE IS ON. THIS OVERHEATING/BURNING OF THE RESISTOR AND WIRES CAUSES THE BLOWER MOTOR TO NOT BLOW AIR WHICH IN PHOENIX, AZ IS A MUST DUE TO SEVERE HOT WEATHER.

A/C & HEATER CONTROLS NOT WORKING. 1ST TIME TOOK PICK-UP IN AND WAS FIXED UNDER WARRANTY AT HUDIBURG CHEVEROLET IN OKLAHOMA CITY, OK. THE SAME THING WAS HAPPENING AGAIN AROUND 1 1/2 YEARS LATER TOOK BACK TO HUDIBURGS AGAIN AND THEY REFUSED TO FIX IT BECAUSE IT WAS OUT OF WARRANTY. A COUPLE OF WEEKS LATER IT BEGAN TO WORK FOR A LITTLE WHILE THEN STOPPED WORKING ALTOGETHER.

THE AC FAN ONLY WORKS ON HIGH (4). THE AC FAN SWITCH HAS A KNOWN DEFECT IN THE RESISTOR SWITCH FOR THE FAN. THIS CAN CAUSE THE WIRING TO OVERHEAT AND START A FIRE. GM HAS ALREADY RECALLED THE HUMMER H3 FOR THE SAME PROBLEM. THE RECALL SHOULD BE EXTENDED TO THE 1ST GENERATION CHEVY COLORADO BECAUSE IT HAS THE SAME FAN SWITCH RESISTOR.

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. WHILE THE VEHICLE WAS STATIONARY, BURNING FUMES EMITTED INSIDE THE VEHICLE. AFTER AN INSPECTION, IT WAS CONFIRMED THAT THERE WERE BURNED WIRES IN THE VEHICLE. THE CONTACT REPLACED THE WIRE HARNESS AND A TEMPERATURE CONTROL REGULATOR. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE. THE APPROXIMATE FAILURE MILEAGE WAS 170,000.

DRIVING DOWN THE ROAD, ALL THE SUDDEN STARTED TO GET A BURN SMELL. HAD TO PULL OVER AND HAVE THE TRUCK BEING TOWED TO THE SHOP. THE PROBLEM IS THE HARNESS CONNECTOR TO THE A/C- HEATING BLOWER WAS BURNING. LUCKILY I HAD DISCOVER THE PROBLEM ON TIME. THIS PROBLEM COULD BE A DANGEROUS FIRE. WE NEED THIS PROBLEM TO BE ADDRESSED AND FIXED SINCE ALL THE OWNERS OF THIS VEHICLE HAVE BEEN HAVING THE SAME ISSUE.

NO SPEED REQUIRED. THE A/C & HEATER NOT WORKING. IT WAS FIXED WHILE UNDER WARRANTY AND IT WORKED FOR A SERIES OF MONTHS AND THEN IT BEGAN ACTING UP AGAIN TOOK THE VEHICLE IN AND IT HAD JUST GONE OUT OF WARRANTY. IT WAS OBVIOUS THAT THE ISSUE WAS EXACTLY THE SAME PROBLEM AND THEY REFUSED TO COMPLETE THEIR WORK. IN THE WINTER OR DURING DAMP WEATHER IT'S IMPOSSIBLE TO DRIVE DUE TO WINDSHIELD FOGGING UP. IT PRESENTS A VERY UNSAFE CONDITION.

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. THE CONTACT STATED THAT THE INSTRUMENT PANEL WAS FLICKERING. THE CONTACT HAD A SAFETY CONCERN BECAUSE THE SPEEDOMETER WAS NOT VISIBLE. IN ADDITION, THE VEHICLE FAILED TO ACCELERATE AFTER A COMPLETE STOP. THE FAILURE OCCURRED ON SEVERAL OCCASIONS. THE DEALER STATED THAT THE BODY CONTROL MODULE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VIN WAS UNAVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 68,000.

THE BRAKE LIGHT SWITCH INSTALLED BY CHEVROLET TO REPLACE THE BRAKE LIGHT SWITCH THAT THEY HAD RECALLED, HAD ALSO FAILED TO WORK. IT STOPPED WORKING SHORTLY AFTER THEY HAD INSTALLED THE NEW ONE, BUT I HADN'T REALIZED BECAUSE I THOUGHT MY BRAKE LIGHTS JUST KEPT GOING OUT. I WASN'T EVEN AWARE THAT THERE WAS A RECALL ON THE BRAKE LIGHT SWITCH AND THAT THEY HAD REPLACED IT WHEN I HAD TAKEN IT IN FOR ANOTHER RECALL ISSUE. I EVEN TOLD MY MECHANIC AND HE JUST REPLACED THE BRAKE LIGHTS. IT WASN'T UNTIL MUCH LATER THAT I REALIZED MY LIGHTS WERE ACTUALLY FINE BUT THAT THE BRAKE LIGHT SWITCH WAS NOT ACTIVATING THEM. I REPORTED THIS TO GMC AND THEY SAID THAT THEY WOULD NOT FIX IT UNLESS I PAID FOR IT OUT OF POCKET ($137 FOR A DIAGNOSTIC TEST, $64 FOR THE ACTUAL REPLACEMENT). *TR

LOSS CONTROL OF VEHICLE ON BLACK ICE; CAR SPUN AND ROLLED AT LEAST ONE TIME. AIR BAGS DID NOT DEPLOY; PERSON HAD TO BE CUT OUT OF VEHICLE DUE TO THE DOORS NOT BEING ABLE TO UNLOCK. *TR

VEHICLE STALLED WHILE DRIVING. WAS ABLE TO RESTART BUT WOULD ONLY STAY RUNNING FOR A FEW SECONDS. AFTER SEVERAL ATTEMPTS IT RESTARTED AND STAYED RUNNING. SINCE THAT TIME THE VEHICLE INTERMITTENTLY STALLS IMMEDIATELY AFTER STARTING AND REQUIRES SEVERAL ATTEMPTS TO RESTART AND KEEP RUNNING. SECURITY SYSTEM LIGHT IS ON. DEALER SAID IT COULD BE THE KEY, OR THE KEY SWITCH, OR THE BODY CONTROL MODULE (BCM), OR ALL THREE. RESEARCH ONLINE INDICATES THAT NUMEROUS CHEVY COLORADO OWNERS HAVE THE EXACT SAME PROBLEM AND HAVE BEEN TOLD SIMILAR THINGS BY DEALERS. IN FACT NUMEROUS OWNERS OF CHEVYS WITH THE PASSLOCK SECURITY SYSTEM HAVE THE SAME PROBLEM. IT FEELS UNSAFE TO DRIVE A VEHICLE THAT STALLS AND WON'T RESTART. *TR

WHEN I SLOW DOWN MY VEHICLE BEGINS TO SPUDDER AND SOMETIMES TURNS OFF. AT FIRST I THOUGHT IT MIGHT BE THE FUEL FILTER WHICH WAS CHANGED BUT PROBLEM PERSISTS. THE VEHICLE HAS SHUT DOWN ON THE HIGHWAY WHEN I SLOWED DOWN FOR TRAFFIC. I PLACE IT IN NEUTRAL WHILE STILL IN MOTION AND TURN IT ON AGAIN THEN IMMEDIATELY PUT THE VEHICLE IN DRIVE TO AVOID GETTING HIT. I FIRST THOUGHT IT WAS JUST MY VEHICLE UNTIL I CAME ON HER TODAY AND FOUND OTHER PEOPLE WITH SIMILAR PROBLEMS. *JS

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. THE CONTACT STATED THAT WHILE DRIVING 65 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALER HOWEVER, THE DEALER ADVISED THAT THEY WERE UNABLE TO PERFORM A DIAGNOSTIC ON THE INFORMATION THAT THE CONTACT PROVIDED. THE VEHICLE WAS NOT REPAIRED.

THE CONTACT STATED THAT HE HAD TO PUT THE VEHICLE IN NEUTRAL AND THEN RESTART THE VEHICLE CONSTANTLY. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER MULTIPLE TIMES WHO WAS NOT ABLE TO NEITHER REPLICATE NOR DIAGNOSE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 60000. UPDATED 06/05/14*LJ THE CONSUMER STATED A MECHANIC STATED THE BATTERY WAS THE CAUSE OF THE FAILURE. THE BATTERY WAS REPLACED BUT, THE FAILURE CONTINUED. UPDATED 06/09/2014 *JS

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. THE CONTACT STATED THAT THE VEHICLE WOULD INTERMITTENTLY STALL WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSIS, WHO ADVISED THAT THE IGNITION SWITCH WOULD NEED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURE WAS ALERTED OF THE FAILURE.

2005 CHEVROLET COLORADO 102,000 MILES. VEHICLE FLASHES "REDUCED POWER" ON INFORMATION DISPLAY THEN SHUTS DOWN ENGINE. LUCKILY I WAS ABLE TO COAST IN TO A PARKING LOT OUT OF TRAFFIC. ENGINE REFUSES TO START FOR A COUPLE OF MINUTES THEN FIRES UP. HAS DONE THIS A NUMBER OF TIMES SINCE. ENGINE CODE GIVEN IS P0601 "CHECK SUM ERROR", IE COMPUTER GLITCH. THIS IS AN UNSAFE CONDITION, INSTEAD OF REDUCING THE ENGINE SO THAT ONE MIGHT GET OUT OF THRAFFIC, THE FACT THAT IT KILLS THE ENGINE IS A MAJOR SAFEYT RISK. POOR PROGRAMMING TO SAY THE LEAST.

THE CONDUIT OR WIRE COVER FROM THE CAB OF THE TRUCK TO THE EXTENDED CABS REAR DRIVER SIDE DOOR CUTS WIRES IN HALF AFTER REPEATED DOOR USE. THIS PREVENTS SPEAKER FROM WORKING AND MAKES AN AIRBAG PROBLEM LIGHT DISPLAY ON THE VEHICLE CONTROL PANEL. *TR

THE ABS LIGHT COMES ON AND BRAKES GO TO THE FLOOR WITH MINIMUM TO NO STOPPING POWER. WHEN THIS HAPPENS THE BRAKES WINE. AFTER THIS HAPPENS BRAKES RETURN TO NORMAL BUT THE ABS LIGHT COMES ON AND STAYS ON UNTIL THE VEHICLE IS CYCLED ON/OFF. ONCE THE COMPUTER SEES THAT THERE IS NO ISSUES WITH THE ABS, THE LIGHT GOES OFF. THIS LEAVES YOU TO BELIEVE THAT THERE WAS A "BUG" IN THE ELECTRONICS. THEN WITHOUT WARNING OR A DURATION OF TIME THE PROBLEM COMES BACK. AND THEN THIS PROCESS STARTS ALL OVER AGAIN. WHATS HAPPENS WHEN I NEED THE BRAKES TO PREVENT A ACCIDENT? AFTER RESEARCHING ONLINE THIS IS A VERY COMMON ISSUE WITH THIS VEHICLE. *TR

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. THE CONTACT STATED THAT THE AIR BAG WARNING LIGHT REMAINED ILLUMINATED. THE VEHICLE WAS TAKEN TO THE DEALER WHO DIAGNOSE THAT THE EXTENDED CAB DRIVER SIDE REAR DOOR WIRING HARNESS THAT INCLUDED THE RADIO SPEAKER, SEAT BELT, AND AIR BAG WIRES WAS BROKEN. THE VEHICLE WAS REPAIRED. THE FAILURE MILEAGE WAS 79,300 AND THE CURRENT MILEAGE WAS 79,400.

FIRE FIRE FIRE AN AIR CONDITIONING RESISTOR PACK OVERHEATS AND CATCHES FIRE IN THE AIR CONDITIONING PLENUM. THIS IS THE FAN SPEED CONTROL RESISTOR. I FOUND MINE TO BE MELTED DOWN AND THE SOCKET THAT IT PLUGS INTO WAS ALSO SEVERELY DAMAGED. THE ONLY RECOMMENDATION THAT THE DEALERSHIP OFFERED WAS THAT I PAY THEM TO REPLACE THOSE COMPONENTS. I PURCHASED THOSE COMPONENTS AND INSTALLED THEM MYSELF. THE SAME THING HAPPENED AGAIN. I DETERMINED THAT THE GROUND USED FOR SEVERAL COMPONENTS IN THE CABIN WAS INSUFFICIENT AND POORLY CONNECTED. I REPLACED THE FACTORY INSTALLED GROUND WITH A HEAVIER GAUGE WIRE AND ATTACHED IT TO THE TUBULAR FRAMING BEHIND THE STEREO . THIS WAS A SUFFICIENT FIX AND I BELIEVE IT IS IN GM'S BEST INTEREST TO REMEDY THIS ISSUE BEFORE A GM VEHICLE CATCHES ON FIRE IN A CARPORT OR WITH CHILDREN ON BOARD. *TR

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. WHILE PARKED, THE CONTACT STARTED THAT THE VEHICLE AND NOTICED THE STARTER KEPT RUNNING ONCE THE VEHICLE HAD STARTED. THE CONTACT SHUT THE VEHICLE OFF AND AFTER RESTARTING IT DID NOT EXPERIENCE THE FAILURE. THE FAILURE OCCURRED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO THE DEALER FOR A DIAGNOSTIC TEST. THE TECHNICIAN WAS UNABLE TO DIAGNOSE THE FAILURE. THE CONTACT REPLACED THE STARTER. THE FAILURE CONTINUED AFTER THE REPLACEMENT OF THE STARTER. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 24,000.

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. THE CONTACT WAS DRIVING 35 MPH WHEN THE VEHICLE STALLED. THE ANTI-THEFT WARNING LIGHT ILLUMINATED PRIOR TO THE FAILURE. THE VEHICLE WAS TAKEN TO THE DEALER TWICE. THE MANUFACTURER WAS CONTACTED BUT THE VEHICLE WAS NOT REPAIRED. THE VIN WAS UNAVAILABLE. THE FAILURE AND CURRENT MILEAGES WERE 89,000.

ON SATURDAY MORNING MY TRUCK WOULD NOT START. I WENT TO JUMP IT, AND WITH NO KEYS IN THE IGNITION AND NOT JUMPED YET THE WINDSHIELD WIPERS AND INTERIOR LIGHT WENT ON. THIS WENT ON FOR OVER AN HOUR. I REPLACED BASICALLY A NEW BATTERY. THE RADIO DID NOT WORK AND DASH LIGHTS DID NOT EITHER. ON TUESDAY, APRIL 17 AFTER I PICKED UP MY SON FROM SCHOOL, THE CAR STARTED TO MAKE A LOUD SCRUNCH NOISE AND STARTED TO STALL OFF AND ON. WHEN I PULLED INTO MY DRIVE WAY AND SHUT OFF THE ENGINE I SMELLED SOMETHING BURNING. I WENT TO OPEN THE DOOR AND IT WOULD NOT OPEN. I TRIED TO OPEN THE WINDOWS AND THEY WOULD NOT GO DOWN. IT WAS SMELLING REALLY BAD LIKE SOMETHING WAS ON FIRE. ABOUT 25 SECONDS LATER, WITH NO KEY IN THE IGNITION THE INTERIOR LIGHTS WENT ON. I PUT THE KEY IN THE IGNITION BUT DID NOT START IT AND TRIED THE WINDOWS AGAIN AND MY DRIVERS SIDE WENT DOWN AND I GOT MY SON OUT THROUGH THE WINDOW. IT HAD TO BE TOWED TO THE DEALERSHIP. THEY SAID IT WAS MY ALTERNATOR WHICH IS GETTING FIXED. READING ALL THE COMPLAINTS I AGREE, WHY HAS THIS NOT BEEN RECALLED. IT'S AROUND 50K MILES AND THE ELECTRICAL GOES. LUCKILY ME AND MY SON GOT OUT. *JS

BLOWER MOTOR FAN SPEEDS WORK INTERMITTENTLY. FAULT WAS FOUND IN BLOWER MOTOR WIRING HARNESS WHERE HARNESS RUNS ADJACENT TO GLOVE BOX. JOSTLE THE HARNESS MANUALLY BELOW THE GLOVE BOX AND THE BLOWER MOTOR SPEEDS WILL GO FROM OFF TO ONLY A FEW SPEEDS TO NORMAL. THIS COULD DEFINITELY BE A FIRE HAZARD. *TR

THE A/C BLOWER CONTROL SWITCH DOESN'T WORK IN POSITIONS 2 OR 3, BUT FUNCTIONS PROPERLY IN POSITIONS 1 AND 4. *TR

THE HVAC FAN MOTOR RESISTOR & CONNECTOR MELTED AROUND ONE OF THE PRONG CONNECTIONS AND WIRE. THE RESISTOR AND WIRE HARNESS ARE LOCATED JUST UNDER AND BEHIND THE GLOVEBOX ON THE PASSENGER SIDE. THE RESULT OF THE BURNING OF THESE PARTS IS THAT THE BLOWER SPEEDS OF 1-3 DO NOT WORK BUT 4 STILL FUNCTIONS NORMALLY. THIS PROBLEM IS MORE THAN AN ANNOYANCE OF THE FAN SETTING BECAUSE THE CAUSE IS MELTING WIRES AND BURNING CONNECTIONS NEAR THE PASSENGER'S FEET. HOPEFULLY THIS CONNECTION CAN BE RECALLED AND REDESIGNED BEFORE SOMETHING SERIOUS HAPPENS. THIS APPEARS TO BE A VERY COMMON ISSUE AS EVIDENCE FROM THIS BLOG. HTTP://COLORADOFANS.COM/FORUMS/67-TECHNICAL-QUESTIONS-TIPS-HOW/112853-HVAC-FAN-MOTOR-RESISTOR-CONNECTOR-REPLACEMENT-MMP.HTML. *TR

THE WIRING HARNESS AND THE RESISTOR PACK FOR THE HVAC BURNS AND IS MELTED AND COULD POSSIBLY CAUSE A FIRE. THIS IS NOT JUST AN ELECTRICAL HVAC PROBLEM. IT IS A GROUNDING PROBLEM, AND CAUSES ALL KINDS OF PROBLEMS. THE HAZARD LIGHTS, BLINKERS, AND STOP LIGHTS ALL STOPPED WORKING ON MY TRUCK. MOST OF THE DASH WOULD GO OUT INTERMITLY. THE AUX PLUGS STOPPED WORKING. I HAD REPLACED THE BATTERY, WIRING HARNESS AND RESISTOR PACK TWICE. GENERAL MOTORS KNOWS ABOUT THIS PROBLEM. IT ALSO AFFECTS THE GMC CANYON, AND THE ISUZU I-280 PICK-UP TRUCKS. THERE SHOULD BE A RECALL TO CORRECT THIS PROBLEM BEFORE SOMEONE IS KILLED. NO BRAKE LIGHTS, NO TURN SIGNALS, FIRE/SMOKE IN THE CAB, ETC. *TT

2005 CHEVY COLORADO WIRING HARNESS ON FAN CONTROL BURNT UP AT MOTOR PLUG. WIRES IN HARNESS STARTED SMOKING AND MELTED PLASTIC. HARNESS AND RESISTOR HAD TO BE REPLACED. *TR

FAULTY WIRING HARNESS THAT BURNS UNDER THE DASHBOARD/GLOVEBOX ON THE PASSENGER SIDE (FEET AREA). THE HARNESS CONTROLS THE BLOWER MOTOR FAN SPEEDS 1,2,3 SETTING AND HAS A RESISTOR. THE WIRING HARNESS/LOOP BEGINS TO MELT AND SUBSEQUENTLY BURN. MY PASSENGER BROUGHT IT TO MY ATTENTION AFTER IT SINGED HIS SHIN; I UNPLUGGED THE WIRING LOOP PRIOR TO CATCHING ON FIRE. THERE ARE MANY ONLINE COMPLAINTS AT CHEVY COLORADO FORUMS I.E. EDMUNDS ETC. THANK YOU. *TR

THE RELAY FOR THE BRAKE LIGHTS UNDER THE DASH HAS FAILED 4 TIMES ON MY CHEVY COLORADO. THE LAST TWO FAILURES OCCURRED AFTER THE PART WAS REPLACED WITH THE SUPPOSEDLY REDESIGNED PART FROM THE RECALL. WHEN THIS HAPPENS THE BRAKE LIGHTS FAIL TO OPERATE AND NO INDICATION IS GIVEN TO THE DRIVER. *TR

TL*THE CONTACT OWNED A 2005 CHEVROLET COLORADO. WHILE DRIVING APPROXIMATELY 35 MPH THE CONTACT NOTICED THICK SMOKE ESCAPING FROM THE DASHBOARD. THE CONTACT PULLED THE VEHICLE TO THE SIDE OF THE ROAD AND EXIT THE VEHICLE. THE CONTACT ALSO NOTICED FLAMES UNDERNEATH THE HOOD. THE FIRE DEPARTMENT EXTINGUISHED THE FIRE. A FIRE REPORT WAS FILED. THE VEHICLE WAS DESTROYED. THE CAUSE OF THE FIRE WAS UNDETERMINED. THE CONTACT DID NOT STATE IF THERE WERE ANY INJURIES. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 52,000.

2005 CHEVY COLORADO HVAC FAN/DIODE CONNECTOR FOR BLOWER MOTOR. THE BLOWER MOTOR HAS BEEN MALFUNCTIONING FOR THE PAST 12 MONTHS. THE A/C FAN SPEED FINALLY HAS STOPPED WORKING IN ALL SPEEDS EXCEPT HIGH(4). AFTER SEARCHING ON LINE I HAVE FOUND MANY CONSUMERS REPORTING THE SAME ISSUE. I HAVE SEARCHED FOR LISTED RECALLS AND HAVE NOT FOUND ANY AND I FEEL THIS ISSUES SHOULD BE ADDRESSED BECAUSE OF THE FIRE RISK IT POSES. *TR

MY TRUCK WONT START DO ALARM OR ANTI-THEFT SYSTEM IT CRANK BUT WONT START. *TR

SEVERAL TIMES OVER THE PAST SIX MONTHS I HAVE BEEN LEFT STRANDED TEMPORARILY BY MY COLORADO NOT CRANKING. THERE SEEMS TO BE NO RHYME OR REASON TO IT. SOME DAYS IT CRANKS FINE. OTHERS, IT MAY TAKE AS LONG AS 45 MINUTES AND SEVERAL ATTEMPTS TO GET IT TO START. I HAVE FOUND MANY FELLOW COLORADO OWNERS HAVE HAD THIS SAME ISSUE AND IT SEEMS TO BE CAUSED BY A FAULTY PASS CODE SWITCH/SENSOR IN THE IGNITION. I BELIEVE THAT THIS SHOULD BE A RECALL ISSUE DUE TO NUMEROUS OWNERS HAVING THE SAME PROBLEM. *TR

THE COOLING/HEATING BLOWER FAN SPEED RESISTOR AND WIRING HARNESS ON THE 2004-2009 CHEVY COLORADO HAS A SHORTING PROBLEM WHICH CAUSES THE TRUCK TO HAVE A SMOKE SMELL AND MAY LEAD TO A FIRE IF NOT CHECKED ON. I FOUND MINE AFTER SMELLING SMOKE FOR A FEW MONTHS AND STARTED CHECKING WHERE IT WAS COMING FROM. I FOUND THE FAN SPEED RESISTOR CONNECTOR AND ASSOCIATED WIRING HARNESS BURNT AND SLIGHTLY MELTED. I WOULD HAVE TAKEN TO THE DEALER BUT IT WAS OUT OF WARRANTY AND DID NOT WANT TO PAY THERE HIGH LABOR COSTS. THIS IS THE SECOND TIME CHANGING THIS OUT IN THE LAST YEAR AND I FOUND THAT THERE IS A COMMON GROUNDING POINT ON THE PASSENGER SIDE FENDER WALL WHICH OVER TIME BECOMES CORRODED AND MAKES A BAD GROUND MOST LIKELY CAUSING THE SHORTING PROBLEM. IF THIS IS NOT WORTHY OF A RECALL THEN I WOULD LIKE TO AT LEAST HAVE A WARNING NOTICE SENT TO OWNERS SO THEY WOULD KNOW WHAT TO LOOK FOR IF THIS HAPPENS TO THEM. *TR

THE PASSLOCK ANTI THEFT SYSTEM ON MY 05 CHEVY COLORADO FAILED THIS WINTER LEAVING ME STRANDED OUT IN THE COLD FOR A HALF HOUR OR MORE ON MULTIPLE OCCASIONS. TO RESET IT YOU MUST TURN THE KEY FORWARD AND WAIT TEN MINUTES, THEN REPEAT THAT TWO MORE TIMES BEFORE IT WILL RESET AND THEN THE VEHICLE WILL START. HOWEVER IT TAKES A SPECIAL TYPE OF SCANNER THAT A DEALERSHIP MUST PLUG INTO THE INTERNET TO RESET THE CODE SO UNLESS YOU PAY A DEALERSHIP TO DO THAT YOU HAVE TO KEEP TRYING TO START YOUR CAR (UP TO A HALF HOUR OF TRYING) FOR THE NEXT 100 IGNITION CYCLES. I HAD TO DO THIS IN JANUARY AND FEBRUARY THIS YEAR IN -10 TO -30 DEGREE WEATHER AND NO CHEVY DEALERSHIP WOULD RESET THE CODE FOR LESS THAN $90. *TR

THIS HAS BEEN GOING ON FOR ABOUT 3 YEARS OFF AND ON. ON AVERAGE, ABOUT TWICE A WEEK, WHEN I TRY TO START MY CAR USING MY ORIGINAL FACTORY KEYS (I'VE TRIED BOTH WITH SAME RESULTS) THE SECURITY ICON LIGHTS UP AND THE TRUCK FAILS TO START. I THEN HAVE TO WAIT 10 MINUTES FOR IT TO RESET. I'VE CONTACTED GM ABOUT THIS PROBLEM AND THEY HAVE TOLD ME TO TAKE IT TO THE DEALERSHIP AFTER THAT HAPPENS. WHEN I WAS FINALLY ABLE TO STOP BY A DEALERSHIP, THEY TOLD ME THAT THEY NEEDED THE PROBLEM TO HAPPEN THERE FOR THEM TO DIAGNOSE AND THAT SCANNING IT WOULD DO NO GOOD. WHEN I HAVE TO BE SOMEWHERE, I HAVE TO NOW PLAN TO LEAVE AT LEAST 10 MINUTES EARLY IN CASE MY TRUCK DOESN'T START. SOMETIMES IT HAPPENS 2 OR THREE TIME IN A ROW AND I'M WAITING 20-30 MINUTES FOR THE SYSTEM TO RESET. I'VE DISCOVERED ONLINE THAT A LOT OF OTHER PEOPLE HAVE PROBLEMS WITH THE PASSLOCK SYSTEM. *TR

ON 23 JUNE 2010 I WAS DRIVING MY 2005 CHEVY COLORADO TO WORK WHEN I BEGAN TO SMELL BURNING WIRES. I SHUT OFF MY VENT FAN SWITCH AND THE SMELL WENT AWAY. I TURNED IT BACK ON AND THE SMELL RETURNED. LATER AFTER WORK I FOUND A CHARRED WIRE CONNECTOR AND RESISTOR NEXT TO THE FAN MOTOR. THE RESISTOR HAD BEEN PREVIOUSLY REPLACED IN 2006 WHEN THE VEHICLE WAS UNDER WARRANTY. THERE ARE ALOT OF POSTS ON-LINE FROM OWNERS OF THE SAME VEHICLE COMPLAINING ABOUT THE SAME ISSUE. I CAN TELL THE SHORT STARTED IN THE RESISTOR WHERE THE CONNECTOR HOOKS INTO IT. THE PART NUMBER OF THE RESISTOR IS 015218254, AND THE CONNECTOR IS 015306069. THE RESISTOR IS MADE IN SLOVENIA. I FEEL THIS NEEDS TO BE A RECALLED ITEM BECAUSE OF THE FIRE HAZARD. *TR

THE BLOWER MODULE WIRE HARNESS CONTINUALLY GOES OUT. I HAVE REPLACED IT TWICE AND THE SAME THING HAPPENS. APPEARS TO ME THAT THERE IS SOME SORT OF SHORT IN THE WIRING. IF YOU TAKE OFF THE BAD HARNESS AND LOOK DOWN IN THE CONNECTORS ONE OF THEM IS ALWAYS BURNT UP. I WORRY THAT IT COULD CAUSE A POTENTIAL FIRE HAZARD. I KNOW THAT I AM NOT THE ONLY PERSON THAT IS HAPPENING TO. I CONTINUALLY CHECK INTERNET BLOGS AND IT SEEMS TO HAPPEN MORE OFTEN THAN NOT. *TR

WHILE DRIVING OUT OF THE BLUE CAR SAYS "POWER REDUCED. TRACTION FAULT." THEN THE CAR ROLLED TO A STOP. POWER STEERING WAS GONE. ALL ELECTRICAL SYSTEMS SHUT DOWN. CAR WOULD NOT START UNLESS SITTING FOR SEVERAL MINUTES. THEN IT RUNS FOR ABOUT A MINUTE THEN SHUTS DOWN AGAIN. THIS REPEATEDLY HAPPEN SEVERAL TIMES ON THE WAY HOME. *TR

2005 CHEVROLET COLORADO 5 CYLINDER 4 WHEEL DRIVE AUTOMATIC 68,000 MI ENGINE MISFIRE 7 TIMES TAKEN TO GARAGE $1,300 PAID AND NO ONE COULD FIX PROBLEM. FINALLY TOOK VEHICLE TO DEALER WHO CHARGED $325 TO CHANGE SPARK PLUGS AND THEN ADMITTED THAT THERE WAS A PROBLEM WITH THIS ENGINE. INTAKE VALVE SEALS ARE DEFECTIVE. NOW VEHICLE NEEDS A $500 REPAIR OF FRONT TRANSAXLE SEAL. ALL ELECTRICAL CONNECTORS ON THIS VEHICLE ARE OF INFERIOR QUALITY, I HAVE EXPERIENCED 3 FAILURES OF STOPLAMP WIRING,4 FAILURES OF SIGNAL LIGHT WIRING, AND 2 FAILURES OF A/C BLOWER MOTOR, ALL DUE TO POOR ELECTRICAL CONNECTORS. MY CONCERN IS THAT IN CASE OF AN ACCIDENT THE AIR BAGS WOULD NOT DEPLOY BECAUSE OF A SIMILAR PROBLEM. THIS IS A POTENTIAL SAFETY ISSUE, AND SHOULD BE EVALUATED. *TR

CHANGED THE BATTERY. CAUSES THE DOOR SWITCH TO GO OUT. THE DRIVER'S SIDE WINDOW, THE DOOR LOCKS AND KEYLESS ENTRY WILL NOT WORK. YOU NEED TO HOPE THE WINDOW IS NOT DOWN IF YOU CHANGE BATTERIES OR HAVE A DEAD BATTERY NEEDING A JUMP START. THE DEALER CHARGED ME $400 FOR A NEW SWITCH. A CHECK OF THE INTERNET SHOWS MANY MANY PEOPLE HAVE HAD THE SAME PROBLEM. *TR

THE THIRD PIN IN A PLUG THAT CONTROLS THE HEAT/AC SHORTS AND CAUSES BURNS MARKS IN THE INSIDE OF THE PLUG AND ALMOST THROUGH THE PLUG. HAD TO REPLACE THE HARNESS. THERE ARE ALSO COMPLAINTS ON COLORADOFANS.COM OF THE SAME PROBLEM. THE PART NUMBER IS A FEATURED PART ON GMPARTSDIREC.COM. PART # PK15218254 HTTP://GMPARTSDIRECT.COM/RESULTS.CFM?SINGLEPART=1&PARTNUMBER=PK15218254 COLORADOFANS.COM LINK IS: HTTP://COLORADOFANS.COM/FORUMS/VIEWTOPIC.PHP?F=8&T=48293 THIS HAS POTENTIAL TO BE A FIRE HAZARD AND PEOPLE SHOULD PROBABLY BE GETTING A RECALL OR REFUND ON THE PARTS THEY ARE HAVING TO REPLACE. *TR

2005 CHEVY COLORADO. BLOWER MOTOR FAILURE ON LOWEST 3 OF 4 FAN SETTINGS. DID ONLINE RESEARCH, LEARNED COMMON FAILURE WAS RESISTOR / CONNECTOR (MELTING OF WIRES AND CONNECTOR). CHECKED MINE. IT SHOWED SIGNS OF OVERHEATING (GREY PLASTIC TURNED BROWN ON ONE OF THE FOUR PINS. BOUGHT NEW RESISTOR AND CONNECTOR FROM GM DEALER AND SELF-INSTALLED. BLOWER NOW WORKS ON LOWEST AND HIGHEST SETTINGS ONLY. CALLED GM HQ. THEY SAID TAKE IT TO DEALER; NO RECALL OR SERVICE BULLETIN OUT YET. SEEMS TO BE A PRETTY COMMON FAILURE BASED ON WEB SEARCHES. I'M SAVING RECEIPTS IN HOPES GM ISSUES A RECALL BEFORE SOMEONE HAS AN ELECTRICAL FIRE. I DO HAVE PICTURES OF MY FAILED COMPONENTS I CAN EMAIL TO YOU IF YOU WANT AND I HAVE LINKS TO THE ONLINE INFORMATION I FOUND RELATED TO THIS ISSUE. THE ACTUAL FAILURE DATE WAS PROBABLY SEVERAL MONTHS AGO, IT HAS BEEN WORKING INTERMITTENTLY ON LOWER SETTINGS; IT FINALLY STOPPED ALL TOGETHER ON LOWER THREE SETTINGS AT THE END OF NOVEMBER AND IT WAS DEC 5TH WHEN I BOUGHT A NEW RESISTOR AND CONNECTOR. *TR

DRIVER INFORMATION CENTER ON A 2005 CHEVY COLORADO Z71 EXTEND CAB P/U SWITCHES FROM ENGLISH TO SPANISH. MILES CHANGE TO KM. ALL WITHOUT TOUCHING ANYTHING. TRUCK HAS 36,500 MILES ON IT. DEALERSHIP SAYS THE DIC IS BAD AND NEEDS REPLACED. OF COURSE THEY FIRST TOLD ME THAT IT WILL BE COVERED UNDER THE SPEEDOMETER SETTLEMENT FOR OTHER GH DIC'S. NOT! THIS IS A FOUR HUNDRED PLUS DOLLAR REPAIR. PROBLEM STARTED ABOUT 32K MILES. *TR

I HAVE A 05 COLORADO. EXTENDED CAB 4X4 W/ 14,200 MILES. I AM THE ORIGINAL OWNER. MORE THAN ONCE I HAVE HAD TROUBLE WITH THE DRIVER SIDE WINDOW WON'T GO DOWN AND THE DOOR LOCKS DO NOT WORK. THIS PROBLEM IS VERY ANNOYING, FRUSTRATING AND TIME CONSUMING. IT IS NOT AN UNCOMMON PROBLEM, CHECK OUT THE ON LINE FORMS RELATED TO COLORADO'S. MY DEALER CHECKED FOR RECALLS AND TSBS WITH OUT HELP. I AM VERY DISAPPOINTED IN GM AS THEY KNOW THIS IS AN ISSUE, BUT THEY DON'T WANT TO OR SEEM TO HAVE AN ANSWER. FOUR YEARS AGO I HAD THE OPTION TO BY FOREIGN BUT BOUGHT AMERICAN INSTEAD. *TR

I HAVE AN 05 FOUR DOOR COLORADO. IN MY YEARS OF OWNING IT, I HAVE S HAD SEVERAL EPISODES IN WHICH THE DRIVERSIDE WINDOW WON'T GO DOWN AND THE DOOR LOCKS DO NOT WORK. THIS PROBLEM HAS TAKEN UP TO A MONTH OR SO FOR THE TRUCK'S COMPUTER OR WHAT EVER TO WORK OUT THE PROBLEM AND START WORKING NORMALLY. I HAVE BEEN TO THE DEALER AND THEY SAY THEY CAN'T HELP EXCEPT FOR A NEW SWITCH WHICH COSTS $200.00. I HAVE ALSO CHECKED OUT VARIOUS AUTOMOTIVE FORUMS AND FOUND MULTIPLE PEOPLE HAVING THE SAME ISSUE AND HAVING IT MULTIPLE TIMES. I HAVE CHECKED FOR RECALLS AND TSBS WITH OUT HELP. GM KNOWS THIS IS AN ISSUE, BUT THEY DON'T WANT TO OR SEEM TO HAVE AN ANSWER. I PAID GOOD MONEY FOR THIS TRUCK AND DID NOT EXPECT A FOUR YEAR OLD TO HAVE MULTIPLE ELECTRIC EPISODES LIKE THIS. *TR

THE NHTSA ITEM NUMBER FOR THIS PROBLEM IS 10013546 MY 05 CHEVROLET COLORADO TRUCK HAS A FAN SPEED SETTING OF 0-4 WITH 0 BEING OFF AND 4 BEING HIGH. ABOUT A WEEK AGO SPEEDS 1-3 STOPPED WORKING LEAVING ONLY OFF OR HIGH. THIS TOLD ME IT WAS THE FAN RESISTOR. ONCE I FOUND THE RESISTOR I NOTICED THE PIGTAIL CONNECTOR AND THE RESISTOR TERMINALS WERE MELTED. I ASSUME THIS IS FROM EXCESSIVE HEAT. AFTER A QUICK SEARCH ONLINE I NOTICED THERE WERE OTHERS HAVING THE SAME ISSUE. THE ONLY REPLACEMENT PARTS FOR THE PROBLEM ARE THE SAME PARTS AND HAVE NOT BEEN RE-ENGINEERED. WHICH WILL EVENTUALLY LEAD TO THE SAME PROBLEM DOWN THE ROAD.. THIS IS DEFIANTLY A FIRE HAZARD AND MALTING IS ONLY 1 STEP AWAY FROM THE FLASH POINT OF PLASTICS. TO THIS MOMENT GM HAS NOT ISSUED A VOLUNTARY RECALL ON THE VEHICLE. CHEVY REFUSED TO PAY FOR THE REPAIRS BUT DID OFFER TO SEND ME A SERVICE CERTIFICATE WORTH $200. THAT GREAT BUT IT DOESN'T FIX THE FIRE HAZARD, NOR THE RECURRING PROBLEMS. *TR

WHILE DRIVING, THE RADIO WILL LOSE POWER, THEN THE A/C WILL STOP WORKING, THEN THE ENTIRE DASH WILL LOSE POWER (NO SPEED, TAC OR GAS GAUGES). THEN ALL WARNING/ FAILURE LIGHTS COME ON. WILL RESET AFTER YOU TURN CAR OFF. BEEN TO DEALER 7 TIMES FOR SAME PROBLEM. *NM

LEFT POWER WINDOW, POWER DOOR LOCKS, CLOCK RADIO, DOME LIGHT QUIT WORKING RANDOMLY. DEALER CANNOT DUPLICATE PROBLEM. ONSTAR DOESN'T WORK SOMETIMES. BATTERY SEEMS TO GO DEAD IF IT SITS MORE THAN 5 DAYS, REMOTE FOR DOOR LOCKS RANGE IS HORRIBLE BUT THEY SAY IT'S NORMAL TO HAVE TO STAND RIGHT NEXT TO THE TRUCK TO UNLOCK / LOCK IT. *JB
