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.
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.
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.
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.
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.
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.
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.
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.
