 The abs light comes on and brakes go to the floor with minimum to no stopping power. when this happens the brakes wine. after this happens brakes return to normal but the abs light comes on and stays on until the vehicle is cycled on/off. once the computer sees that there is no issues with the abs, the light goes off. this leaves you to believe that there was a bug in the electronics. then without warning or a duration of time the problem comes back. and then this process starts all over again. whats happens when i need the brakes to prevent a accident? after researching online this is a very common issue with this vehicle.

 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 a/c blower control switch doesn't work in positions 2 or 3, but functions properly in positions 1 and 4.
07/22/2010
 The hvac fan motor resistor & connector melted around one one of the prong connections and wire. the resistor and wire harnes are located just under and behind the glovebox on the passenger side. the result of the burning of these parts is that the blower speeds of 1-3 do not work but 4 still finctions normally. this problem is more than an annoyance of the fan setting because the cause is melting wires and burning connections near the passenger's feet. hopefully this connection can be recalled and redesigned before something serious happens. this appears to be a very common issue as evidence from this blog. http://coloradofans.com/forums/67-technical-questions-tips-how/112853-hvac-fan-motor-resistor-connector-replacement-mmp.html

 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.

 Faulty wiring harness that burns under the dashboard/glovebox on the passenger side (feet area). the harness controls the blower motor fan speeds 1,2,3 setting and has a resistor. the wiring harness/loop begins to melt and subsequently burn. my passenger brought it to my attention after it singed his shin; i unplugged the wiring loop prior to catching on fire. there are many online complaints at chevy colorado forums i.e. edmunds etc. thank you.

 Tl- the contact owns a 2005 chevrolet colorado. while driving at any speed, the contact noticed that the abs and traction controls would illuminate without pressure. also the air conditioner switch would either illuminate or de-illuminate when hitting 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 private mechanic inspected the vehicle and advised the contact that the electrical system needed to be repaired; however, it was non repairable. the current mileages were approximately 96,000 and the failure mileages were 95,000. bw

 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.

10/03/201045142
 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 serching 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.

 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 ismade in slovenia. i feel this needs to be a recalled item because of the fire hazard.

 The blower module wire harness continully goes out. i have replaced it twice and the same thing happens. appears to me that there is some sort of short in the wireing. if you take off the bad harness and look down in the connectors one of them is always burt up. i worry that it could cause a potentional fire harzard. i know that i am not the only persone 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.

 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 electeical connectors on this vehicle are of inferior quality, i have experrienced 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 problen. 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. *tr

 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 http://gmpartsdirect.com/results.cfm?singlepart=1&partnumber=pk15218254 coloradofans.com link is: http://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. *tr

 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

 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

 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

 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
