Chevy Colorado and GMC Canyon Electrical Problems



  • I have an 05 colly that developed this power lock and driver side window issue. I have checked all fuses, d/c'd battery and left it sit for four hours. I tried removing switches and opening them up, cleaning and re-attaching them. I even went as far as doing the same for other three doors. and still nothing. It has been two days since issue started and all I did was to remove driver side panel to fix my exterior lock. But here is the funny thing, I contacted two Chevy Dealers in my area today. Both dealerships say they have never heard of this issue before now. I have search several forums to find many people having the same issues. Kinda funny that alot of others are having this same issue and dealerships have nothing to say except to bring it in for a diagnostic costing $90.00 an hour. :mad:

    If its under warranty should be no charge. If out of warranty and it is broken then I would contact Chevy and plead your case. Be polite and shed big tears.
  • I have 1 2008 GMC Canyon purchased September 28, 2007 and the battery went out at 350 miles, battery replaced, and went out 11 days later, would not jump start. Dealer kept it 5 days and was not able to duplicate problem. 3 days later battery dead again, dealer kept it 8 days and unable to duplicate problem. 5 days later battery dead again, 604 miles on it. Dealer still unable to duplicate problem. I have filed with GMC to have it declared a lemon. I have requested a new vehicle, or a full refund, waiting for GMC to review and offer a solution.
  • As for the dealer not being able to locate the problem, I dont believe that. It's more likely they just don't want to take the time to find it. Next time tell them to check for an intermittent short to ground somewhere close to the firewall. I have had two defective under-dash wiring harness' replaced to repair faulty lites and blinkers. These shorts caused problems in one of the computers, so I made them replace it also. It took a ton of determination and close to two years to get these problems straightened out to this point, so stay with it. It is my opinion that the dealer will have to see that determination before they will take on the responsibility. Keep all dealer reciepts, and know your states' Lemon Law, these may come in handy. Anyway, hope this helps.
  • i am having the same problem, have you tried the replacing the relay yet?
  • Just a followup on the issues I had with the windows and door locks over the summer.

    In 20/20 hindsight it looks like the problem was the fuse box that the dealer replaced under a precautionary "service order". Since I had the fuse block replaced, and battery I haven't had any more problems. I think it's pretty evident that the fuse block must have some defect in it that caused the BCM and battery to die. Again, Chevy covered the fuse block but refused to cover the battery or BCM. I did the complaint line thing up the food chain and they offered me their "Smart Care" package, "a $390 dollar value!" that consists of 6 oil changes and a tire rotation or two. No, they are not using Mobil 1.

    The dealer, Gustman Chevy of Kaukauna went to bat to try and get the Chevy rep to cover some of the $800 in electrical problems I've had with the truck but the Chevy rep held firm, no dice. Ok, no problem. No further Chevy purchases. I'm sure by the time I'm ready for a new truck Chevy will be bankrupt.

    The dealer however did give me a check for about $250 from a 'good will' standpoint as they agreed that all these electrical problems happening so quickly made sense that the shorted fuse block caused the other stuff to fry. I'll give them good marks since they stood behind the sale even if the manufacturer won't stand behind their product. I hope to do business again with Gustmans; occasionally they get Fords and other products as trade-ins... I might buy one of those from them, but a Chevy? Never again.

    I am sure you are upset with this matter but seriously do you really think Chevy is going bankrupt? Not a chance in our life time, they are too successful of a company. If this would have happened with you buying a Toyota would you have felt the same way?
  • I'm have the same problems too, except my truck will not start at all, the engine will turn, but it wont start up. the windows and locks will now work. did anyone ever get a fix on the problem?

    Has anyone any idea what I need to replace to get the heater fan to work on 1,2, and 3?
  • tommctommc Posts: 68
    Bad thing about this is having a vehicle that is just not reliable, and you're doing without it on numerous occasions. Terrible situation. Any update on this? :confuse:
  • tommctommc Posts: 68
    Usually the blower resistor located in the hvac air box. Check in at AutoZone for the part and location. About $20 if I remember correctly.
  • Hi:
    Yes, after all attempts by the dealer, and GMC, failed to reproduce the problem after
    about a month in the shop, GMC has agreed to buy the truck back and give me a
    full refund. It took a LOT of threats of a lemon lawyer to convince them this was
    the best option for them.

    I bought my 06 Colorado truck in Sept. 06. I am now on my third set of lights, a year and a half later! It sounds like a ground problem to me. Anybody have the same problems. My only other beef with the truck is paint chips. I have found chips out of the paint on the front bumper, hood, the front of the rear fenders, and on the rear bumper.

  • On December 28 GMC agreed to give me a refund for the vehicle. I mailed in all paper
    work requested on January 2, 2008. On January 7, vehicle returned to me. On January
    10th the battery went dead for the fifth time. I called GMC support on January 11, and they now refuse to give me a refund or replace the vehicle. They offer to pay me for the 30 days the vehicle was in the shop. I will have to hire a Lemon Lawyer.

    Whenever i shut the truck off the horn makes alittle chirp not a full honk, anybody know anything.
  • poncho167poncho167 Posts: 1,178
    Sounds like something related to your security system? Some people's cars security are automatically set once they remove the key and a few seconds after that.
  • puregreenpuregreen Posts: 24
    The key is still in the ignition but in the off position, it just started doing it any other ideas. Thanks
  • poncho167poncho167 Posts: 1,178
    So it sounds like you have a security system, right? If you do and this is the same chirp you had been getting when the alarm is set then I would say this is an ignition switch problem. Have you consulted your dealer?
  • puregreenpuregreen Posts: 24
    Just whatever the factory has in it. Im checking with them they said never heard of it, plus frt axle seals are leaking hoping its covered under warranty.
  • I have a 2004 Colorado with 60K on it. Luckly I have not had any of the major problems I have heard discussed here. I do have a problem with the rear half door wiring harnesses. The wire used in them was to stiff and both have broken wires in them at the flex point. Has anyone else had this happen?

    this morning I purchased some window tint for my 05 canyon. I continued to pull off my driver side door panel. I then cleaned the window. I plugged the switch back up to lower the window a couple of inches and the driver side window would not move. I tried all the other windows from the driver door and they all worked. I tried the mirrors they worked. I tried the door locks, they did not work. I went to the passenger side, the door locks did not work there either. I tried the keyless entry button. The horn dtill chirped like it should but the doors didn't lock or unlock. I contacted the local dealer and they said they have never heard of the problem. Which from the postings I have just read through that is not unusual. I have read quite a few postings on a few different sites and there are a lot of canyons and colorados that are haveing the same problems. Most people are saying it is the BCM. Has anyone figured out the exact problem? Oh and by the way when I contacted the dealer my warranty expired 8 days ago. Some luck huh???
  • On April 21, GMC bought my Canyon back, 3 months after I filed thru BBB and having a dead battery 12 times in less than 1500 miles. Of course I lost about $1200.00 because they disallowed the cost of the spray in bedliner and side moldings I added, the $560.00 sales tax on the trade in, and $500.00 incentive. But I DID get a check from GMC, but it took 3 months of them fighting and delaying at every opportunity they could come up with.

    I don't think most companies would honor warranty repair on that issue being that you created yourself, unfortunately. I read here on the forum of someone who figured out the window switch thing and how it is related to its connection. Look back over the posts.

    Intermittant Multiple Cylinder Mis-fire:
    I experienced an Intermittant Multiple Cylinder Mis-fire that occured abruptly and continued until I replaced the exhaust valve cam position sensor. I performed this repair based on a OBDll code and chose to replace it since the other referenced sensors were not available at the local parts store. I immediately started the truck after replacement and had no further issues. The next morning I drove the truck about 5 miles and the same exact syptoms occured again. I parked the vehicle for about 20 minutes while I went into the store, came out and it ran perfectly fine since. I have noticed though that the power doors locks do not function and the drivers window is inop. Any ideas? I have reviewed the blogs posted and have noticed a number of discussion on the GM Cylinder Head issue , though have a hard time believing it could be the same. I also believe there is a GM issue for the door locks and window though have not seen anything.

    :cry: :D :mad: :confuse: :lemon:

    Hi I have a 2004 Chevy Colorado Crew cab with 45k miles. It has always been well taken care of but lately, I have been having small electrical issues. The inside dome light and rearview mirror courtesy lights work when they want to. When I engage the hazard lights, the rear blinkers flash, but not the front, they just stay solid. With regular blinker use the rear units flash, but the front units don't blink or come on at all.
    The radio stays on even after I remove my key and shut the door, but it will turn off sometimes when the passenger door is opened and closed.
    I was thinking maybe a ground issue? All of the fuses check out good. Any Ideas??
