The contact owns a 2005 Chevrolet Colorado. While driving various speeds, the contact noticed that the ABS and traction controls would illuminate without applying pressure to the brakes. The air conditioner switch would shut on and off while driving over a pot hole. The dealer was unable to duplicate the failure and advised the contact that there were no recalls. The contact did not inform the manufacturer nor was the vehicle repaired. A local mechanic inspected the vehicle and advised the contact that the electrical system needed to be repaired; however, it was non repairable. The current mileage was approximately 96,000 and the failure mileage was 95,000.

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.

Colorado 5-cyl

  • 45,142 miles
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.

Ac blower fan works in high only. Upon checking the wiring I notices the resistor and the wire harness were burnt which caused the problem. I replaced the wire harness and resistor which fixed the problem. Upon further searching I found many others with the same problem and some that ended up in fires under the dash.

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 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.

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.

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.

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.

1. normal driving. 2. brake light switch failure. Brake lights inoperable along with inoperable cruise control. There were no consequences, however having no brake lights could result in sever consequences. One has to wonder if a wreck had occurred would it be considered my fault since my brake lights not functioning was the cause of the wreck? 3. I replaced the brake light switch with a new GM part purchased at a GM dealer. I have 3 of the last 4 failed brake light switches. The first failed switch was thrown away. The P/N of the most recent failure is 25796381. That is also the P/N of the part purchased by me today. The P/N for the other 2 switches is: 15912229 & 1518647. The last time my brake light switch failed was 03/2008. I have owned my truck since 3/2005 I believe.

Colorado 4WD 5-cyl

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.

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.

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 gmpartsdirect.com/results.cfm"singlepart=1&partnumber=PK15218254 coloradofans.com link is: 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.

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.

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.

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.
