That is a great post, one of the best and most informative on the problem. It makes sense and it sounds like logical troubleshooting. I wish you had posted it back in 2007 before I took the Colorado in for service to the local Chevy dealer. Of course the Chevy dealer said, "Don't believe ANYTHING you read on internet, we're the experts..." Uh-huh, yeah, right.
If you still own a Colorado and take it to one of their dealers for this "nonexistant problem", just remember, the Colorado is "the gift that keeps on giving year after year"... to their service department.

Keep in mind that in addition to the fuse problem, the drivers switch module can also be the other problem with the window/lock defect. Some people have replaced it and problem solved (about $175). I replaced a friend of mine module and silicone greased the connections to the module and it was fixed. Not everyone will have the fuse problem before mentioned. It is just two areas that are highly suspect when this occurs. Another Colorado I fixed just by siliconing the connections to the module and used it over again. I will guarantee that disconnecting the battery cables and etc. don't fix it, you just got lucky if it started working after that. A lot of people report the problem when the weather is cold, which backs up the connection problem as being a big issue.
Gee, Randy Wise in Milan is only about 60 miles from me.

I have had to have the BCM replaced because the truck was stalling in the middle of the Freeway, In houston this is not a good thing. My Blower only works on High but on occasion will work on other speeds, tends to have a mind of its own. Also, the Drivers side Electric window also has a mind of its own. Now that the warranty is up, of course. The Dealer wants to charge me 98.00 just to look at it. When I told him of the previous BCM issue (under warranty) and now that the truck has 100,000 miles on it and clearly out of warranty, he told me that if it were the same issue, they would have to contact Chevy Corporate to get a decision rendered on if they would pay for it or not, or partially. I have heard alot of horror stories about this vehicle with related problems. It is sad that me being a chevy owner for over 35 yrs and me splurging for a non-base model for once, that I would get burned like this. I suppose my father may had some great wisdom by only buying and swearing by FORD. I suppose I should have listened. Does anyone have any ideas on what may be causing these two issues? BTW I just went to the dealer to have the brake lights fixed, a recall.. but it cost me 33.00. Intersting

Sorry to hear about your problems Mark. I don't know how much time you'd had to go through the 450+ posts here, but your truck has all the lemon symptoms, the driver's window, blower, BCM, tail lights. If you haven't experienced it yet, there are also huge problems with a fuse block, the engine head, instrument panel, door locks, blower resistor, dead battery, CD player that doesn't work.
I've been following this thread since 2007 when I started having trouble with the fob/driver's window. There have been several good theories and it could be any one or a combination of issues. Bad grounds, bad fuse blocks, bad connectors, too small an alternator. The list goes on but none of the possible solutions are easy to implement or confirm.
Your best bet is to get the truck running and sell the think as quickly as possible before the next $1000 dollar problem appears or is uncovered. I'm serious. I think the truck is a great concept, bought mine new, loved the thing up until the nightmares with the electrical system started. The Chevy dealer was less than useless, randomly replacing parts saying, "This time's the charm", while the dollars flew from my pocket into theirs. I got Chevy involved and they tried dodge the bullet by offering four oil changes and a tire rotation. Since they have become Obama Motors there's a couple of "Customer Care Representitives" lurking the forum that will try to get you to spend more dollars at a dealership, but other than that, Chevy probably just hopes the Colorados and Canyons end up in the junkyards as quickly as possible. Customer satisfaction, loyalty and quality obviously don't mean much when the worst that happens is you get an infusion of Obamadollars to keep on trucki'n.
I finally gave up on my Colorado this summer. I traded it for a Toyota. I never, in a million years thought I would buy anything but American but Chevy deserves bankruptcy.
Seriously, cut your losses and get out of the Colorado. Unless you have a really good mechanic that can troubleshoot these weird problems, or the time to tinker with inspecting every electrical connector and ground on the truck, the desire to replace the alternator with one that can handle the load, get a new battery about every 3 years, don't mind burning BCMs out, window modules etc... get out from under it while you can.

I have a 2008 Canyon crewcab, have 90,000 kms on it, have had a problem with the tail light which I fixed with some wd-40, other than that I must say I have had no problems with the truck, sorry guys! guess I got the good one! Love the truck! Hope I haven't jinxed myself...!

sorry Mark 1962, but I would have never paid the $33 for the brake light problem as it is under recall. Regarding the Blower and drivers window, first the blower problem.
1. Look under the dash on the passenger side by the blower motor you will see a connector with I believe 5 fairly heavy wires. If you unplug that, you will find some terminals that are dark and starting to burn. This is the blower issue problem. I removed the resistor assembly (2 screws), trimmed the plastic material from around the terminals and soldered wires to the terminals. I cut the plug on the vehicle side and spliced the wires together with good electrical butt connector splices. Problem was fixed permanently.
2. The drivers window/door lock problem is a little more intense. Remove the drivers window/lock module and remove the plug in connections and use silicone grease (dielectric grease), available at a parts store on the connections. Reinstall and see if that fixes the problem. If problem does not re-occur it is fixed. If it does, using a wiring diagram, trace the circuit back to the door lock and window fuses. Check for voltage at the orange wire where it enters the drivers module for 12 volts while someone is operating the window or door locks. If no voltage, there is a problem between that and the connection that supplies power to the fuses. As a last resort, if no other problems are found, replace the drivers window/lock module (about $135-150). Give me a message with your email address, I can PDF the wiring diagrams to you.
BTW, the engine stalling issue you mentioned was probably not with the BCM (or Body Control Module), it was with the ECM (or engine control module). They may have told you the wrong unit. The BCM does nothing but control body functions, (lighting, windows, radio, etc). The ECM has total control over the engine. Based upon my 35+ years as a mechanic, problems rarely are traced actually to the computers. It is usually a sensor or connection problem. Experts agree with the above statement, as many computers are replaced and sent back to the rebuild center that are found with nothing wrong with them. I recently repaired a transmission speed sensor problem by removing the computer plug and silicone greasing the connection. Had I replaced the computer, it probably would have cured the problem in the connection also, but silicone grease is $1.50 where a rebuilt computer is $200+, and they would have gotten a computer core that there was nothing wrong with it back at the rebuild center.

You ARE lucky you did get the good one. Had an 07 bought brand new nothing but an electronic NIGHTMARE!! Dealer was upset because I sent neg. feedback on G.M.workmanship questionaire. After 3 trips to fix same problem= 3 neg feedback,dealer told me "take your truck somewhere else we don't care about your problem/don't want your business." Told G.M... thier response was "what ya want us to do about it?"
ANYONE with one of these trucks should "fix it & sell it." A.S.A.P.!!!

I recently had problems with my 2005 Colorado. I had a dead battery, malfunctioning driver window (other 3 work), door lock malfunction. I did a little research and came across this site. I thought I had an isolated electrical gremlin. Guess it turns out I'm just one of many with the same gremlin (or should I say monster). I managed to "fix" the problem by disconnecting the driver control module connections.
This is just one of my many problems with my truck. Cyliner heads (fixed 8000 miles and the truck has not been the same since), parking and headlamps malfunctioning (bad connectors), misfire during rt. hand turns (Chevy couldn't figure that one out either. It still misses and is a hazard & liability), windows don't go down (then mysteriously work 2 minutes later), cruise control (didn't work for 1 day and then mysteriously started working), heavy carboning of the throttle body, and now my most recent problem. What's next???
I still think its poor wiring and bad grounds (I get real bad static shock during the winter when I shut the doors. Don't know if that has any bearing on bad grounds.
As long as I can remember, all of my immediate family members have driven GM vehicles. I am extremely displeased with my Colorado. It has been nothing but a headache. Don't get me wrong, I like my truck for a lot of reasons, not to mention it's a great looking truck. However, with all the enduring headaches, repeated trips to the dealer(with no results of course), and cash thrown into it, I may have no other choice but to dump it, along with my loyalty to GM products. I really don't want to do it, but after reading the previous 49 pages of gripes with nothing more than getting referred back to the dealer where they can blindly throw parts at it, it's a great possibility. I will continue to monitor this website. GM needs to solve this issue by the time I'm ready to sell and get someone on here other than a rep referring me to another dealer and inviting me to throw away more hard earned money or GM will lose more than just myself as an "unvalued" customer. I will make sure to spread the word that GM cannot be trusted as a reliable auto maker. Especially when my profession puts me in front of 125 to 150 youths a day, each year. That's a lot of potential GM buyers.
Ok. I'm done ranting. If anyone has any info related to any of these problems, please reply (for the sake of all our sanity).

Other than the "recent" posts, there is nothing more to say. This thread addresses the "drivers window/lock and blower issues". I believe the last 2 pages outline what can be done. Other than that, the only thing I can help on is the wiring diagrams that are in PDF. I believe they are also located on this forum or in this thread. If not, contact me private message and I will send you the PDF's to your email address.
You can also contact the representative from the factory that is mentioned throughout this thread and request an Incident number to get this resolved at a local dealership.
