Regretfully an owner of a 2004 Colorado Z71 4x4 w/ 130K. Been a Chevy fan most of my life, but more based on the days before computers got involved. I'm currently dealing with the ABS and the power window control system problems. Unbelivable how many posts on both these issues and the countless numbers that aren't even aware of this web site. Christina, Sarah, "Peggy": with the large number of folks you have sent to the dealers and still no feedback on what these problems .....please ??? Evidently the problem is too big and too expensive for GM to recall. Too bad they won't admit that they have these problems because GM is losing more customers every day despite their great advertisements on that hypnotizing tube (I MUST HAVE A NEW CAMARO).
 
I have worked on my cars all my life because I won't trust my vehicle repairs to anyone else. I know it's done right and I avoid new unrelated unexpected problems. I was fortunate to learn from my Dad who was once a GM mechanic. I have also worked many years on the electronic systems on military aircraft, so my insight on the electro-mechanical aspect has served me well. I think I can speak with some knowledge, so I would like to add my 2 cents on these issues.
 
This vehicle is plagued with electrical problems. I have taken my door panel off three times to check the connections between the relays and the motor. Power (+12Vdc) is intermittent to the control unit. The switches that drive the relays have clean contacts and test good each time. If anyone has an electical diagram that shows power distribution to the door, it would be much appreciated. Currently, when I start the vehicle, the windows will go down once, up once, down again and then freeze, consistantly. If I didn't know better, I would try to tie this to a computer problem, but it makes no sense to tie them together. So, when I get a diagram, I'll isolate the bad wire/connector and post the location. (Peggy....don't hate me for this!) It worked on my wifes' 2004 Jeep. Someone posted the broken ground wire in the drivers door boot. As for the ABS, what a pain.
 
The ABS intermittently lights, the brake pedal pulses, till I get over the 26 mph threshold, then annoying lights up the dash for the remainder of the drive into work. Checked the wire coming off the hubs and getting pulses from both front wheels. So I know that the mag sensors are working, which saves me $260 in replacement (Sorry Peggy.....don't curse me!). So my conclusion, based on some of the other posts, is that I have an intermittent electrical connection somewhere in the engine compartment. I'm thinkin the issues with the electrical block ( that won't be recalled) will be my starting point. When I get the electrical diagram, I'll find that sucker, and I'll post my findings and hopefully bring relief to all the people that can't / won't give their money to the GM Service Department.
 
If anyone has a pdf of the electical system, I could certainly use it.
 
A Note to Peggy: It amazes me that with all these posts that GM has not dedicated an engineer / tech to troubleshoot these problems and broadcasted the word out. My analysis: either 1) they don't care cuz they're makin big bucks off of many; 2) they're incompetent and can't figure out what the problem is; or 3) they have determined what the problem is and the cost to admit they need to recall exceeds what they're willing to spend. Either way Peggy.....you're looking really bad here ! My Love for GM is gone (not that they care)!

Of course they don't care. The only person they need to impress now is Obama since he's the one keeping them in business, satisfied custoners are no longer important.
 
I've followed this thread since 2007. The story is always the same, somebody finds this thread because of some weird electrical problem, (usually the door lock/fob/battery thing). If they go to the dealer, they replace X, Y or Z at random (BCM etc) with a variety of explanations, (can't run two windows at the same time, can't leave the keys in the ignition etc). And usually the thread poster returns with some other weird electrical problem sooner or later, (unless they sold their truck).
 
I know the Colorado/Canyon were never really big sellers so you are probably right, it just isn't cost effective to GM to have a recall. Just piss off a "small number" of unsatisfied customers while making good profit off of their misfortune for buying your defective product in the first place.
 
As far as "Peggy" goes, they claim to not be on commision. They claim to only moitor threads like this to "help customers and take back information to GM" or something, yet they can't get any kind of real GM tech to address this thread. All they do is "appologize for your frustration, give me your info so I can send you to a GM dealer!" If you want to take them up on the offer, good luck. If you aren't happy with all the money you spend, perhaps they will offer you a "jelly of the month club" prize like four oil changes and a tire rotation, "worth $450 dollars!". My suggestion, find a competent mechanic, work on it yourself, or cut your losses and sell the truck and buy something from a company where they work for the customer and not a presidential benefactor.

we have a 2005 canyon that has had numerous electrical problems. in reading the hundreds of other posts i now realize that we are not alone in these issues. we've had problems with the power door loks, the power windows, the dome light, the console lights and multiple trips to the dealership for recall repairs on the brake lights. now, our trun signals are clicking twice as fast as normal and the turn indicator lights on the front of the truck have stopped working. we dont want to get rid of the truck since it only has 70k miles and its in great shape mechanically, but these ongoing electrial problems have gotten ridiculous. any advice or help in these matters?

If you decide to work with a dealership, which I completely understand isn't an option or consideration, please let us know as we would like to be available to assist as best we can. Have you already had some of these concerns addressed by your dealership or independent shop before?

Sarah

In reply to: "our turn signals are clicking twice as fast as normal and the turn indicator lights on the front of the truck have stopped working."
 
Very simple, easy fix! ... You have burned out bulbs on the front turn signals ... just buy new ones at you local auto parts store and you should be GTG. I believe you need a 3157 bulb, but check that application chart/book at your parts store.
 
You should check all your bulbs at least every few months. If you haven't replaced any other bulbs since 2005, you should check them all (brakes, headlights hi/lo, corner marker, reverse, license plate).

thanks for the help, but we've taken to the dealership repeatedly. as i said in the opriginal post, we've had the brake lights fizxed 3 times, as recently as a month ago, and the newly repaired brake lights just went out again. this truck has had electrical issues since we've owned, which is a real shame, because we love the truck in spite of all the trouble.

"I understand. We're here if you should ever need anything! GM Customer Service".
 
Yeah, how about some real attention to the problems the Colorados and Canyons have, LIKE A FRICKING RECALL for the poor owners that trusted GM and haven't junked their trucks yet.
 
But that isn't going to happen, is it? Doesn't fit with GM's motto, "Once you have their money, never give it back".
 
For the post with the turn signal problem, yes, sounds like you have a burned out bulb and that should be a simple fix.
 
On the brake lights, check the sockets. If I remember correctly, they have a ring of prongs around the light bulb, and eventually they take a set and contact get spotty. The way I noticed was taking the truck in for an oil change. They check the lights, and after the second time replacing the same tail light I took a closer look and discovered it was a contact issue.
 
The way GM has washed their hands on the problems these trucks have is disgusting. They have earned the right to go bankrupt.
