2005 Chevrolet Colorado: engine overheating

Filed Oct 20, 2015 · Electrical · 184,000 miles · AZ

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.

This truck has a recurring problem where the rear brakes freeze into position when the emergency (parking) brake is applied. Has been happening for 10 years since I bought the truck new. If the emergency brake is set, the rear brakes will not release when the lever is released by the driver. I am stuck where I parked with a set of frozen rear brakes. In order to get home I am forced to drive with the rear brakes engaged causing a severe overheating condition in the rear wheels and potential for a brake fire near the gas tank. Gm said there was not a problem and refused to fix this problem under warranty. It is still a problem and gm still refuses to fix this prolem even though there are thousands of drivers with this "freezing rear brakes" issue. My work around? I don't use the parking brake. I have a stick shift and the engine compression alone will not hold the truck in place on a sloped driveway, so I have to carry a block of wood to place behind the wheels as my "parking brake". Gm needs to recall chevy colorado trucks for this systemic failure in the rear brake systems.

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.

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.

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.
