general problems of the 2004 Chevrolet Colorado - part 1

Ignition safety module known as pass lock security. This causes my vehicle not to start and give a code and a light on the dash for the pass lock security. The vehicle was fine then I went into a store came out and put the key in the ignition, the lights on the dash came on but it would not crank. This is very hazardous cause it could happen while you’re driving anytime, which could cause the vehicle to go into security mode and turn vehicle off making it very dangerous for passengers in vehicle. This is a problem with other chevy Colorado's when I research this problem.

One day, after I turned my truck off, I noticed that my taillights and overhead cargo light remained on. Key was out, truck was off, but the lights stayed on. So for the time being, I disconnected the battery. I brought it to a mechanic, who ran the codes that came back that the rear driver turn signal was high, the rear passenger turn signal was high, and the overhead cargo light was high. He checked the entire truck for a short, replaced the taillights, replaced the fuse box, replaced the body control module, and numerous other attempts at a repair, with no success. I was without a vehicle for many months, since I can't afford the absurd prices of the current vehicle market and was hopeful it could be fixed. Reading through some other complaints/online threads, this seems like a fairly common problem with these vehicles. Electrical issues that affect my ability to use a turn signal are a huge safety concern and this needs to be addressed.

Body control module, bcm. Controls everything. Air bag can deploy, breaks can lock up. Mine, the hazards were staying on. Chevy dealer says they are on national back order and gm is canceling those orders after so long placed. “we can get you one from a junk yard for $350 but gm won’t let us properly program them with correct codes, and so many times they won’t take, and I can’t return the part”. My response to gm already and to congressman westerman, bbb, and the wh. A part such as the on board computer, safety first, should never come from a junk yard and if gm doesn’t want to supply the part as we all know they need them for newer cars right now…. . You, the nhtsb and all of us are in danger. There is an expiration date on our cars, but we’re not being told. A computer that controls everything in a vehicle is more important than a safety belt. Me not wearing it kills me. Me being told by the dealer I could leave my fuses out and put my arm out the window. Boy I hate being a retired sgm, cause I ain’t allowed to put my boot in a six.

I've had to replace 2 heater blower resistors due to a meltdown, this is a potential fire hazard and should be put on a recall notice. I was driving around 40 mph at the time .

Tl the contact owns a 2004 Chevrolet Colorado. The contact stated that the interior lighting, door chime, and radio did not turn off. The vehicle was taken to mayse automotive group (2032 s elliott Ave, aurora, mo 65605) where it was determined that the wires running from the rear driver's side door had to be replaced; however, the parts for the repair were no longer being manufactured. The manufacturer was not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 190,000.

I bought this vehicle in 2014 with only 86000 miles on it. I had to have brand new key cut and programmed when I purchased it. Starting in July of 2016 I started having issues with it not starting and cutting out. Now it won't start at all. It is the theft system not allowing it to start. I have read thousands of complaint about this issue over many different gm vehicles. Some nearly causing wrecks, stranding people with kids , etc. Why has this issue been let go for so long. Does gm not care about their customers. I bought another chevy right after I bought this truck. We got rid of it because it was doing the same thing.

I too have experienced problems with the hvac system of this truck. I have had to replace no less than 4 resistors and connectors due to melting and burned connections. I have not had to replace a single fuse. My hvac is once again inoperable and I have opened and inspected each connection point to locate the problem. I have found multiple connectors to be burned or melted. This problem has been flagged by the nhsta in the hummer h3 vehicles which use the same hvac system. The Chevrolet/GMC/isuzu Colorado/canyon (gmt355) should be included in this recall. There is no reason these connections should get hot enough to bubble and burn plastic before burning out a fuse. I can provide images upon request. I can also provide an example of a failed connector in the hvac speed control switch for physical inspection. I have set the "fire" flag on this report as there has been evidence of multiple electrical fires on multiple occasions in several locations in the hvac system of this vehicle.

A/c heater resistor and plastic connector for both resistor and blower motor arced and melted. Also air bag light is on.

Turn ignition to off position and park indicator light and radio stays on. Have to jiggle key to get to go off. Come out several hours later and park indicator light and radio are back on. / also, heat and air control fan only works on high speed. I was told it was a resistor ,I replaced resistor and it still continues to do this. I can reach down and jiggle the resistor and it works on all speeds for a short while only. Have a friend with GMC canyon that has had this problem since his was new also.

The contact owns a 2004 Chevrolet Colorado. The contact stated her vehicle would stall intermittently after it was turned on. The failure was diagnosed, both the dealer and manufacturer were aware of the failure. The vehicle was not repaired. The failure mileage was 117,000.

This incident occurred twice. It involves the heater blower motor resistor assembly. 8 years ago my daughter used put her back pack on the passenger floor where it repeatedly made impacted the connection to the blower motor relay assembly. This eventually caused the pin and socket on the orange wire to separate to the point where it arced and burnt. I found and repaired the socket when the heater would only work on high. On the 16th of Dec 2013, a passenger size 12 shoes accidentally, and unwittingly kicked the same spot and caused the same fault. I repaired the socket again. My complaint is the resistor connection is in a spot to easily service, but it is in a vulnerable spot for accidental contact. I believe it needs a robust protective cover, either metal or plastic. For people that cannot repair their own vehicles, this situation could cost them a couple of hundred dollars. My other electrical fault is the right side window motor. It quit working couple of years ago, and I was able to take it apart and clean the brushes. It worked for a couple of years until it stopped a couple of weeks ago. I replaced the motor because I could not find brushes to replace. I am convinced that the brushes failed because they were made brittle from slamming the doors too hard by the passengers. The doors are light and it is common for them to slammed. The brushes or the motor need to be more robust.

The switch which controls the fan speed for the heat and a/c quit working. The fan only works when the it is set on high.

The vehicle was parked and started up due to the snow/ice to melt the windshield. The fan would only work on the high setting which is "4". I replaced the resistor as it was burnt. It worked ok for a week and then burnt out again. If I jiggle the wires it will sometimes work on 1, 2 or 3 setting but not for very long. I have replaced 3-4 resistors and I'm tired of replacing them. Seems to me that this should be a recall as tens of thousands if not hundreds of thousands of Chevrolet Colorados have had this problem. Just do an internet search and find the thousands of reports yet gm is not doing anything about it. Also, one time while driving the fan quit and the entire dash lights went out including the speedometer, rpm gauge and fuel/battery gauges.

Abs fault light went on. Turned off engine, restart, light off. Goes on and off randomly.

Vehicle keeps stalling at idle or as you are slowing to stop at traffic lights, drive thru's. . . Acts as if it isn't charging properly. Have replaced battery, plugs, belt tensioner, drive belts. This is dangerous!!! I almost got hit again in morgantown! brake lights, head & tail lights keep going out as well!!! my husband recently diagnosed with cancer. I am having to drive him back & forth to wvu hospital in the Colorado. It is dangerous having to drive this thing like this! talking to other Colorado owners experiencing same/similar problems! truck does great on highway, except for lights going off & on. Please help!!! truck now has about 119,000 miles.

Dashboard lights not always coming on at night only odometer lights up.

Intermittent non working power door locks wipers headlights and windows! there are hundreds of these incidents posted online. There looks to be thousands of dollars in repairs with no solution!.

The electric system is is knocking out the brake light and cruise control on all 2004 and up chevorlet Colorados. I was driving home from work just to be pulled over because the brake lights wasn't working he told me the guy behind me almost nailed me because of it. I didn't know! but I did know of the Colorados having a big problem with the electric system knocking out the brake lights and cruise control. So I got on line to see just how bad it was and found out it's no laughing matter all most every chevorlet Colorado truck has this problem. Just thank of comming to a stop from 65 miles an hour and not having brake lights, I and some people on the road with me got lucky today. I called two of my closest gm dealers to try to get it fixed today and asked did they know of a problem like this and they did but gm has no recall it's at the owners exspense to get it fixed, while I told them both what I found out online. . . . The answer from one no one has died yet. **** that's what it takes to get some things fixed now days for some one to die before the companies to fix a defective vehicle. . . Please some that can force gm to fix the problems with the Colorado trucks please help us owners of these trucks outwe can't keep spending money like this I also have spent houndrerds on other problems through out the seven I owned the truck. . . Times are tight can't just got to and buy a nother vehicle. . . Look online these truck are prone for trouble and people don't know it until the have brought the truck.

I have replaced the master switch that controls the locks and windows once already. Got a new switch and it still doesn't work. I called gm and they said that there were no recalls on my truck for that issue. I can only lock and unlock the driver's side door with the interior panel or the remote- the rest of the door do not lock/unlock.

For beeing mechanically inclined this is definetly one problem I cant fix. I did the pads and rotos on my 2004 chevy Colorado, all went well, nice and easy. Later that week my abs light came on. I had my breaks checked and the mechanic said it wash showing wheel speed sensor. I bought the part and replaced it nice and easy again. The light turned off for about 2 min then came back on. The next time I went to drive my truck I turned it on, the sensor was off then the abs system started engaging on and off making a wiered pump sound and making my brakes ingage and disingage. This happens for about 20 sec then goes away and the abs light comes back on. I thought nothing worse could happen after having the computer replaced twice on the truck. This is worse.

My air bag light stays on. I think it is a broken wire in the rear door.

I noticed that when using the remove only the driver's door would lock and unlock. I go into the truck and used the panel and again only the driver's door would lock and unlock. I paid out of pocket to replace the switch inside the truck on the driver's door that controls the windows and the locking system. It worked for about 8months and it has gone out again.

The hvac blower motor resistor assembly melted on the vehicle. The current passing through the unit is sufficient to melt the connector and degrade the wires to brittle. I believe this is a possible fire hazard. A number of CO-owners have found the same defect. The connection in question terminal (c) goes to a ground distribution block that might not be sufficient.

The ignition key has twice needed to be replaced as the key itself seems to lose the ability to turn in the ignition. I assume that the key wears out over a period of time, but I have never had this issue with any other vehicle that I have owned. I have had to call a locksmith both times and have a new key made in order to start the vehicle. Both times I was in a parking lot.

2004 chevy Colorado zq8 hvac blower harness and resistor. Part was replaced at approximately 15,000 miles under mfg warranty with identical parts. Again out of warranty with no new revised parts at 45,000 and now again at 77,000 miles. Harness and resistor failure had gotten so hot each time that it had melted the harness to the resistor. Possible fire hazard, with severely burnt wires. Looking it up on forums this is common on all gm model Colorado and canyon trucks, gm knows of the problem, but refuses to offer a revised part or real solution.

I replaced a second brake light switch. First one was replaced under recall. Dealer said no open recalls for my vehicle. I had to pay out of pocket. Since this is only a $10 part, it's not the price but the safety issue. I have filed a complaint with you on this same issue on 12/16/2005 - (please refer to odi number 10145757). Again I don't know how long this switch was defective, but I have noticed other vehicles tailgating more frequently in the last couple of weeks. This could have been out a day, or months. I am very concerned with a future accident, or an accident involving other 2004 chevy Colorado owners, since the part I just purchased from the dealer has the identical part # - 25796381 - as the one I replaced. Without going into major detail, I again ask you to refer to the above odi # as this complaint has the identical basis. Since I only have 44,900 miles on my truck, I would like to see a permanent fix for this part since it is a dangerous situation to drive without brake lights. Thanks for your time.

Cruise control still not working had it in to have it checked they replaced the recall than I took it and still did not work than took it back than they replaced another switch than they said the cruse was commanding on than I took it and tryed it and nothing worked.

I have a 2004 chevy Colorado, and this past week the brake light switch went out and caused my brake lights and cruise control to not function. My mechanic informed me that there was recall 09v310000 to address this issue. When I called my local dealer, they said that the recall was already filled in 2007 by the previous owner, and they could not help me. When I called gm corporate office, they said that due to the high miles (125,000) on my truck and the recall already being filled that they could not help me. The woman on the phone said that if the miles were not so high they would help me out. Also, she then went on to say that even with high miles they would have fixed it if the recall wasn't taken care of in 2007. She said that gm will not take care of a recall a second time even if it is the same problem recurring. It is ridiculous to think that there is a known problem with this switch, has been recalled, has been fixed, still not functioning correctly, and gm will not address the issue when it continues to fail. If it is such a problem that gm will do a recall for the part, why is it not a big enough problem to fix correctly or another time with the faulty part fails again? the consumer should not be stuck with fixing a part out of their own pocket for something that continues to fail and is under recall currently!.

Blower motor resistor connector overheats, whereas a terminal burns, creating a poor connection and no power.

With the revelation of the gm ignition recall problem, there are much more ignition problems that were not included in the recall. The problem is in the ignition cylinder and alignment with the passlock or passkey sensor. My problem started shortly after the vehicle went out of warranty and I was told by the dealer that it was a $1000. 00 repair. I can not afford $1000. So I have lived with it. Because of the misalignment it causes the ignition to think that the vehicle is stolen and disables the fuel injectors, it has left me stranded quite a few times along the road waiting for the computer to manually reset after 10 minutes, it has also cost me several towing bills until I did an internet search and found out how widespread this issue is. If the misalignment is causing this to happen what will it affect as the problem worsens. This issue is not covered by the current recall but deserves investigating . Thank you bob.

I have a 2004 chevy Colorado. The problem I am having with my vehicle is the a/c switch will not work on setting 1 through 3. Although 4 works all the time. I have had it fixed 3 times since I bought the truck by a chevy dealer yet the problem keeps happening, and once again it has stopped working. I have read many automobile forums and it seems many people are having the same problem yet chevy has yet to issue a recall.

My 2004 chevy Colorado LS 4x4 has an issue with the passlock system that shuts my truck off while driving down the road when this event happens I loose my power steering. This is a well known problem that has no fix. The chevy dealer says it's a common problem with no real definitive solution.

Multiple failure of blower resistor 3 occurrences in 6 month period each time the resistor had to be replaced a new plug assy was installed after the 1st occurrence.

Blower fan works intermittently. Does not work on settings 1,2 and 3, will only work on setting 4. Fan will resume working on all speeds if fan motor tapped with foot or hand. .

Vehicle sometimes will not start. Once it happens, let sit for 10 minutes and it will then start. Taken to dealer and was told it is the passlock (security) system. Checked internet, seems to be a common problem with newer gm vehicles.
