"I'm supposed to return to the dealer in the AM to have them work with the factory techs. But i'm already into this for nearly $600 for diagnosis and BCM replacement, and presumably the bill will only go up from here.
Yeah, pretty much, welcome to teh GM service department. I went through the same thing. Replace the BCM, it will cure the problem. Oh it didn't? You want your money back? Well, ahhhh, the BCM was bad anyway. Let's try replacing something else. How about a new battery? That will cure the problem. Oh it didn't? You want your money back again? Well sorry, but the battery probably needed to be replaced anyway. Oh? It was only three years old? Must have been a bad battery that went before it's time. Oh it was a GM battery? Well, ahhhh... Oh how about if next we replace...
Catch the drift?
Remember the First Rule of Feregi acquisition, "Once you have their money, you never give it back..."
My advice, seriously... there is no simple, single fix, just a host of possible causes. I've been following this thread since there were 50 posts. There are many thoughts, some good, some weird that may or may not help, basically since the problems come and go at whim it would seem. "I sacraficed a virgin on the hood and the fob started working", kind of thing. There are far more posts about dealerships replacing BCMs and other expensive parts that didn't solve the problem.
I Honestly believe your best bet is to quietly sell your Colorado or Canyon as soon as you get it running and learn a lesson about buying GM products. I really tried to stay with the truck but after 5 years of reoccuring weird electrical problems and no support from Chevy (other than invites to spend more money at a dealership so they could continue to experiment at my expense), I finally gave up. Best decision I ever made was to get rid of that truck.
The Colorado and Canyons truly are the gift that keeps on giving... to their repair departments.

Gosh. That's pessimistic
But I see where this one might be starting down a bad path. FYI, I didn't mention that the battery was replaced less than a year ago, with a better-than OEM spec unit. (and the problem was neither better nor worse after wards). This is only my second GM product in the last 30 years (the other was a trouble-free Venture van). You want a lemon ... try my old Chrysler Pacifica AWD ... that was a horrendous POS!
Actually, aside from this, which has really just been an annoyance until the last month, I've been quite happy with my Canyon. It's given a steady 17-18MPG overall mileage, even when thrashed, towed my popup, carried countless loads of yard waste to the community recycle (and I mean big ones), carried innumerable loads of kids and sports equipment to football, baseball and softball, taken two trips to California towing a trailer, and been nearly trouble free (one fan clutch, one thermostat in almost 120k miles, did both myself -- although the climate control fan has always been a noisy annoyance). I got a great purchase deal on the vehicle in fall 2004, and would consider it an overall very good value over about 7 years. Basically, I just want a legitimate fix for this so I can get back to not worrying about my vehicle

It's not pessimism. Check out more the posts on this site,they all state the same issues/problems with LITTLE/NO help Except to (give us your $)" go to the dealer."
If this site has all these posts think about ALL the folks who don't know about this site who have'nt posted here..
Pessimism?? NO just straight up FACTS!

When the truck "dies on turns", are the rpms dropping way off and the truck shakes? If so, this sounds like a throttle body that needs cleaned. Mine was stalling and I took it to a friend and he cleaned the throttle body. It runs much better now (except for the random electrical issues).

I am sorry that this situation is frustrating at the moment, colo04canyon. I see that you're working with your dealership, and that your vehicle is going in today (December 19th). Have you been working with Customer Assistance at all? If you were to email us your Service Request number, we could look into the situation further. Or, if you would like to establish a case with us, please email us the following information: your name/username and contact information (phone and address), the last 8 digits of your VIN and current mileage, the name of your involved dealership and a description of the times you've been in for this specific concern (lock/unlock problems).
Thank you very much for your patience with us as we work to sort through this concern with your vehicle,
GM Customer Service

Before the days of electronic remote entry/start for cars, when you had 'something' purely decorative attached to that chain (metal, stone, etc) - what did you call that?
Or, what do you call that small extra pocket on men's pants (especially jeans or work pants)? Those are fobs. I believe the English word dates back at least to the early days of the North American trains (early 1800's), but my etymology dictionary says: [Probably akin to dialectic Low German 'Fobke', small pocket.]

"When the truck "dies on turns..."
Yes, that was another fix, cleaning the throddle body. Mine was doing the same thing, "bogging out" and the shop (non-dealer) that I was working with cleaned the throddle body and it was fine after that. This is something that is pretty common on high milage vehicles.
The 'concept' of the Colorado/Canyon is a good one, that's why I put so much effort into keeping the truck. Ming got just shy of 19mpg. I really liked the truck but it ended up being a losing battle. It is one thing do get the throddle body cleaned, or change the brakes, alternator or starter, these are things you normally expect.
It is another thing to have to deal with design defects like a bad engine head or tail lights that may fail at any time, or fuse blocks that burn up, or blower resistors that repeatedly fry or CD players that don't work and then the endless weird electrical problems... windo/fob thing, instrument cluster, turn signals, wipers, the "weird list" is endless. That's why I finally gave up and cut my losses.
Anyone can design a product poorly, Chevy, Toyota, doesn't matter. The real deal though is who supports their customers vs those that look at their misdesigned product as a "gift that keeps on giving" to their service departments.

First of all; almost 100% of the time, BCM's or ECM's are blamed but do not fix the problem. Many ECm's (engine control modules) or BCM's (body control modules), are returned to the repair center and they find nothing wrong with them (learned this at a GM Tech training center).
Look at the last few pages of this problem. I can narrow it down to one of 3 things ( or a combination "rare").
1. Your drivers window/lock module is bad (replace it for about $165).
2. Clean and grease the connections to the module with silicone grease.
3. There is a 12v supply problem to the module from the fuse box.
There have been issues with the connections in the fuse boxes. I believe there may be a service bulletin on this, I'm not sure.
If necessary, have the GM TECH read all this thread, especially the last 10 pages I would guess.
Test the supply voltage to the window/lock module (located in the drivers door below the switches) WHILE THE LOCKS OR WINDOWS ARE ATTEMPTING TO OPERATE. This may take 2 people. One to actuate the buttons while the other one tests with a wiring diagram and VOM.
Hope this helps, Dennis

Well. Just got the truck back from GO GMC repair in Golden Colorado. I think they really fixed it. They did replace the BCM (echo skepticism again heard throughout this thread about the efficacy of this), and then found one (or more) broken wires in the wiring harness where it comes through to the driver's door. An initial test showed that the lock/unlock was working 100% correctly, both fro the fob and during park/drive transition. Interestingly, the remote range was better than I think it has ever been since I owned the vehicle -- and the outside temp is about 28F (cold, snowing, after dark). So. Based on this thread, I'll wait a while to see, but initially it seems fixed. Of course, it did set me back $630 (with tax). They had the vehicle for probably 20 business hours.

I guess the word fob is an american thang. lol . In canada we just call it a remote. When you attach other things to your key chain, i dont know what you call them. Attachments,accessories,trinkets,I dunno. When someone has alot of shit on their key chain,we dont say "man,you have alot of Fobs on your key chain". We say "Man,you have alot of shit on your key chain".lol
