Problems with 2004 Chevrolet Colorado ELECTRICAL SYSTEM

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.. *tr

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. *tr

My check engine light has been coming off and on continuously for the past six months, however it was diagnosed and it wasn't a big problem. recently, i have been able to unlock my truck using the keyless entry and when i am in the vehicle the doors will not lock with the lock/unlock button on the door. when driving, after accelerating over 20 mph, the doors use to lock themselves, but now they do not. normally when i put my truck in park, all the doors will automatically unlock. this has not been happening. i am scared to keep anything in my truck and fear that this might cause more serious problems and expenses. i would like to know if this has been happening with other colorado's? it seems like since i have gotten this vehicle it has been one problem after another and i am very disappointed in chevrolet. *tr

The anti-theft system in my truck (and in many other chevy's, apparently) will prevent the car from starting. it happens randomly, but frequently. *tr

The first and ongoing problem grinding in front left, driver, side wheel area. many attempts have been made to fix this problem, they started out changing the whole front end, along with alignments, after some adjusting the problem will seem to go away only to return with in 2 months second, tires worn from inside out alignment, new tires, i was told one reason was the truck was dirty. i do not feel this is a reason for tire wear. new tires same problem. third, truck not engaging when shifted into gear. this is on going, we have taken it in many times, the modular for the 2-4h-4l drive was changed, still have problem, they claim can not fix if it does not happen with them,, i video taped it, they will not look at video. problem is intermittently, and have been asked to do different things to the truck when it happens, the problem is happening more often now, the problem seems to be growing. and still no answer to this or other problems, the dealer should have took back the truck and replaced it, if they can not be fixed. *tr

The dashboard lights will stop working if your driving at night and turn the car off and then turn it back on. they will not work until the car sits for a long period of time. this started soon after buying the car brand new, but the dealership couldn't find anything wrong. second complaint, the heater/air conditioner fan had an electrical fire at where the harness plugs into the fan motor. the fan will only work on high. when i looked online at other complaints about the same problem, i unplugged the fan and noticed the plug was burnt. i have photos that i can send. it appeared the electrical fire continued down the plastic plug to where the wires are exposed. this could have been a major incident if i didn't notice it. there are a lot of complaints about this with colorado trucks online. also when driving at night, my dash lights and instrument lights flicker as if there is another electrical short somewhere in the wiring harness. *tr

I have a 2004 chevrolet colorado extended cab that continues to experience intermittent electrical problems. the airbag sensor light comes on unexpectedly, the fan blower intermittently stops working on settings 1-3, and the front turn signal bulbs go out every 5000-6000 miles. i can usually brush the components under the glove compartment to get the blower working, and the airbag sensor usual goes out after a week or so. *tr

The brake light switch has failed multiple times. it was covered twice under a recall. switches only last 1.5-2 years. there is no warning or dash light when they go out. i have almost been rear ended twice. happened again april 13, 2015. i drove it straight to the dealer when i found out in traffic. i knew it was the brake switch again and the dealer confirmed. the dealer called gm to see if they would cover the replacement. they refused. the dealer gave me a discount as they know it is an issue and charged me $87 to change. this is the second time i have had to pay. he gave me this number to call but that was no use as they refused last time. 800-222-1020. most concerning to me is the lack of concern by gm to fix a know safety issue in the brake and light system. someone probably has or will be seriously injured or killed. they need to come up with a comprehensive fix and at a minimum continue covering failures under warranty. not fixing the design problem then making money charging people is not right. the dealer who did the work last time is five star chevy in dallas, tx. craig greene was the representative who tried to help me with gm if you need to contact him. dealer tried but gm did not take ownership for their product. *tr

Tl* the contact owns a 2004 chevrolet colorado crew-cab. the contact stated that when the battery died and a new battery was installed, the automatic key fob entry became inoperable. in addition, the driver's side window would become inoperable and could not be opened or closed. the vehicle was taken to the dealer who advised the contact that the driver's side door control switch needed to be replaced. the switch was not replaced and the vehicle was not repaired. the manufacturer was notified of the failure who advised the contact that there were no recalls and offered no further assistance. the failure mileage was 77,000.

Blower fan works intermittently. finally stopped working on settings 1,2 and 3, will only work on setting 4. replaced resister 1st from dealer, the climate switch panel. finally the fan wouldn't run @ all, took to local mechanic replaced wiring harness & fan motor. took about a year to get truck fully repaired. *tr

Chevy colorado trucks risk of fire! this truck is on its 3rd a/c & heat fan speed control resister and corresponding connecting plug. the first two were covered under the factory warranty, this last one was not. each resister and plug in connector has been on the verge of catching on fire. at times you can smell smoke in the truck. if the fan speed control is on 1,2,or 3. off & 4/high work ok. each plug has melted and is a charred black and the contacts are no longer supported by the plug. the intense heat has charred the resistors corresponding connection socket. i have photos of the resister and plug for your inspection. upon request. and the old units for you. if you do a web search for chevy fan or blower speed control stops working you will find this is a common problem. this connection needs to be redesigned before it burns down someone?s house because they parked their car in the garage. updated 10/20/2017*cn

The chevy colorado extended cab model has a history of the wire breaking in the same location causing the air bag (srs) light to remain on. i believe this manufacturing defect may not activate the srs in the event of a side impact. the wire in question is located inside a rubber boot between the rear doors and the main cab body. it seems if you use the rear doors it will develop a broken wire. *jb

Electrical, heater blower only operates on high, 1 2 and 3 does not, new circuit board installed, failed again, hat to stick a paperclip in harness to get it to run correctly. *tr

Front turn signal lights don't work fixed twice now saying the fuse box is the problem. blower motor does not work after 3 blower motor resistors a new blower motors and connectors. sometimes the radio does not work. the truck has stalled driving on the highway 3 times all loss of power. *tr

For the past year my 2004 colorado has intermittently failed to start when ignition key is first turned to start position. by turning the key off and than on again it will start. it does this once in while, but always seems to start the second or third turn of the key to the start position. twice over the last two years it wouldn't start at all and i had to let it sit for ten minutes or so, than try again, at which time it started. i believe the problem is caused by the pass lock security system. because its out of warranty i haven't done anything about it. *tr

Blower fan works intermittently. ocassional smell of burnt wires. finally stopped working on settings 1,2 and 3, will only work on setting 4. this seems to be a common problem on the chevy colorados that gm will not acknowledge. *tr

Driving from dealer to my house after buying truck the brake lights, wipers, horn, cruise control all stopped working at same time. *jb

Soon after new vehicle purchase in 1/04, cruise control periodically became inoperative. i do know if the brake lights were also inoperative. dealer could not duplicate the malfunction and did not diagnose a problem. this problem occurred approximately 5 times over the next 2.5 years. recently, the cruise control became inoperative again, as well as the rear brake lights. i took the vehicle to the dealer and informed them that a recall had been issued, though i had not received a recall notice from gm. i presented the dealer with a printout of the nhtsa recall information. dealer stated that there was no recall for my vehicle, and since my warranty had expired, i would have to pay for repairs. repair consisted of replacement of the brake light switch. the total cost of the repair was $175.04. i'm not sure if this has any connection, but the vehicle was inspected just prior to expiration of the warranty. one week later, and after expiration of the warranty, the battery died and required replacement. *jb

Some times, the car will not start if the ignition key lock light blinks. i have to wait ten minutes so that it starts i have taking it to the dealer and they have said that it has a faulty ignition housing, of course they want to charge me a lot to fix it. i believe is a factory defect. my truck has a salvage title, so the warranty on it was voided. i have heard of other chevy colorado trucks with same problem. *tr

Their seems to be a short in the electrical system. shortly after purchasing the vehicle the clock in the stereo would not keep time. no matter how often you set it you can leave the vehicle parked for an hour or so come back and the clock has the wrong time in hours. i have recently had to replace all the bulbs on the passenger side "front and rear". now the driver side park-signal light will not work when the vehicle is in gear. after you put the vehicle in park the light will come on. also the electric windows do not always work. the tires on the front end have excessive wear on the in side. *nm

dt: the contact states when trying to start vehicle it starts shaking. the service dealer states that this is an intermittent problem, and there is a technical service bulletin. the consumer states when the vehicle does this after approximately 35 minutes the vehicle will start back. the service dealer replaced the relay switch. but after a week the problem recurred. the manufacturer referred the consumer to the better business bureau. *ak

6 months after purchasing a brand new 2004 chevrolet colorado zq8 3.5l extended cab i noticed while driving on the highway wind noise coming from the passenger door as if the door was not completely closed. 2 months later and it was so loud i had to turn my radio over half volume just to listen to my radio. i had the truck seen by the dealership which i bought it and they said that the cause was misaligned. the b4000 door assembly front right align 9635 w5 0.30. they adjusted the door and for 2 months there was no wind noise. the problem keeps occurring needing alignment. i also have a problem with the screws coming loose on the driver side door causing a metal binding sound everytime i open and close the door. each time i open and close the door the screws are loose enough to were i can hand tighten them. i also had a computer problem in this vehicle as well. a year after having my vehicle out of nowhere and no warning my truck would not start. it would crank over but would not start. i had it towed to the dealership and the invoice states: scan computer codes p2610 stored in pcm. mandy codes stored in bcm. ran bulletin search. found pcm failure replace pcm. reprograms and clear codes recheck ok. however since the new computer was placed in the truck the alarm light will come on and stay on every once in a while. *nm

Battery on colorado keeps going dead. 4 trips to the dealer for solution to this problem. replaced body control module and battery.*ak

Tl* the contact owns a 2004 chevrolet colorado ls. the contact was driving 5 mph when every warning light on the dashboard continuously illuminated. the vehicle was taken to the dealer numerous times but the dealer was unable to determine the cause of the failure. the vehicle was repaired several times but to no avail. the manufacturer was contacted but offered no assistance. the vehicle was not further repaired yet the failure persisted. the failure mileage was 70,600.

Air is seeping out of the passenger side glass because it may not have been properly sealed at the factory. also, the battery warning lights comes on upon starting the vehicle. the light dims then brightens as the vehicle is driven. this indicates a failure in the battery. although the battery is fine. this maybe due to an electrical short. dealership is not being helpful with resolving any of the problems.*ak
