Recently reported ELECTRICAL SYSTEM problems on 2005 Chevrolet Colorado

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

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

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

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

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. the failure mileage was 35,000.

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

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.

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

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

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

I have owned my 2005 chevrolet colorado 4 door 4x4 since nov. 2004 i have had tires that puckered, 3 radios installed,blower motor switch replaced 1 time and is now out again, a leak in the fire wall that has been in 2 times to be fixed and still leaks in hard rains, a defective brake light switch. and the worst gas mileage of any vehicle i have owned in the past 30 years. my 71 monte carlo with a 400 big block and 3:73 rear end gears got better gas mileage. chevrolet said to wait till it had about 10,000 miles well it has 52,000 and still can't get past 16.5 mpg. and only 11 if towing anything. the radio has been fixed and the brake switch replaced i still have leaking fire wall and very poor gas mileage. i drive a nice straight shot 71 miles one way with only 2 stop signs between start and finish of my drive each day for a total of 140 miles of pure open interstate driving in a rural area! shame on you chevrolet! *jb

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.

Truck has push button 4wd controls. three times it has switched to 4wd from 2wd i was at slow speed once in reverse and each time i was turning the steering wheel to the right. had the truck into the dealer for a defective power steering pump and reported that to the dealer, they said they could not duplicate the situation. *jb

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

About 1 yr. and 1 month after i bought a chevy colorado, the thing shut off on me. the first time it left me on the side of i-55 and did not want to start. it did though, but the engine light was on, it soon went off. the dealer reprogrammed the computer. it has shut off on me 4 more times. the dealer will not fix the truck b/c it is not storing "codes". also, the traction control on the truck seems to engadge itself at the oddest of times when there is really no tire slippage and this has me sputtering and jumping while i'm trying to drive in traffic. at first start up, the truck has always made this rattling ping noise out of the muffler. every time i step out of the truck, i shocks me, i beleive due to the nylon in the fabric seats. the turn signal will only "tick tock" when it wants to. the hood on the truck will "bow" or "bubble" in and out while driving, usually on the inerstate when there is some little wind blowing outside. the alarm on the truck has gone crazy on me a few times. i can unlock the door, it will go off but the radio inside the truck will be playing. if i were to cranck the truck up, turn the engine off, get out, and lock the door, the alarm will be going off about five minutes later. this cycle will keep going on until i reset the computer by pushing the gas pedal three times. all the dealer and gm wants to offer me is an extended warrenty, which the warrenty i have now is doing me absolutely no justice, i refused it. they told me that they cannot work on the truck b/c they cannot duplicate the problems at which they drove it twice, and the computer is not storing codes. this problem seems to be compleately spurratic and unpredictable. i have invested alot of money into this truck and still owe on it. i refuse to be forced to pay for and drive a hazzard. *nm

2005 chevrolet colorado 2wd pickup with 3.5 litre engine and manual transmission. regular cab. this vehicle is poorly designed and supported. there has been a hesitation and backfire since it was new in may 2005. numerous attempts to have gm fix it have met with stoney indifference and total non suport of their (gm) suposed warrranty. it also has a foot operated parking brake and this on a manual transmissioned vehicle is in my opinion an accident waiting to happen. *jb
