2005 Chevrolet Colorado Electrical System Problems

Vehicle taillights failed to function when lights come on at night. I became aware of this when another motorist stopped beside me to tell me. Fuse and lightbulbs work when tested.

IGNITINION SWITCH TRIGGERS ANTI-THEFT SECURE ON TRUCK SO IT WOULD NOT START I WAIT FOR 10 MINUTES THEN IT STARTS, DEALERSHIP COULD NOT TELL ME A FEW YEARS AGO WHEN I TOOK IT, AND MECHANICS TELL ME ITS A DEFECTED IGNITION SWITCH BUT ONLY DEALER CAN FIX IT, ITS A RECALL THING FROM WHAT MECHANICS ARE TELLING ME. ITS A SHAME MECHANICS OUTSIDE THE DEALERSHIP KNOW MORE THEN DEALERSHIP ON WHAT IT IS BEEN RECALL.

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.

I'VE TRIED TO HAVE A GARAGE REPAIR/FIX MY HEATER/FAN MOTOR THREE TIMES TO NO AVAIL. HEATER WORKS ON HIGH ONLY...AND NOT ON ANY OTHER SPEEDS.

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.

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.

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.

AIR BAG LIGHT COMES ON MAKING IT UNCLEAR IF OCCUPANTS ARE PROTECTED OR IF AIR BAG WILL JUST GO OFF ON ITS OWN. PROBLEM IS WIRES IN BACK DOOR JAMB BECOME FATIGUED AND BREAK CAUSING FAILURE OF AIR BAGS. VEHICLE IS ALSO CONSIDERED AN INSPECTION FAILURE AS WELL IN MASSACHUSETTS.

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

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.

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.
