Did my son's Ford truck he bought used. Someone disconnected all the dome light and fuses and etc because a door switch was open and the BCM "door open". Used the software to determine that the right rear (quad cab) door switch was open. Pulled the right rear door panel and located the bad switch and replaced it. It saved pulling all the door panels to find the problem.

Check out my posts #426 and #438 in this discussion. This fixed it for me. I had partial luck pulling the battery cable but I think the only reason that worked is that you had the hood open and changed the temperature on the loosely fitting clips on the fuse, causing enough expansion to make an electrical connection. The extra strands of copper I shoved in with the fuse helped insure a strong connection, and while not elegant, hasn't failed since.
What bothers me is that they just replaced your fuse box and you still have the problem. Check the power lead in your driver's door switch with a voltmeter to see is the hot 12V input to the switch drops to almost zero when you hit the switch to move the driver's window. That will tell you the line from the fuse box can't push enough current through to do the job. The weak link is usually the clips griping on the fuse.
Good luck!

Another fine job by GM service techs.
Remember the first rule of Feregi acquisition, "Once you have their money, you never give it back." GM has the same attitude.
A $1400 bill!!!! OMG.
I'm surprised the "I appologize for your frustration" people haven't tried to scavenge this thread for a while. I guess 'Peggy' is finding greener pastures someplace else.

My guess is replacing the fuse block fried something, most probably the door modue. Hit or miss, you can try replacing the door module and it may solve the issue (until it fries again).
For what it's worth that fuse lock was covered under warranty for me but they said it was like $400 dollars.
Your best bet though, sell the truck and be money ahead in the long run.

Well, my Colorado was a "satisfactory vehicle" when it wasn't having weird and expensive electrical problems because of the design flaws. My next vehicle has been "more successful" because it is not a GM product.
Honest, Sarah, Christine, Cameron, Peggy or whatever you go by, honestly, what can you actually do for the poor folks that still own their Colorados and Canyons and haven't traded them or junked them yet?
A friend of mine had a GMC Envoy that the drivers lock/window module burned up internally. Replaced the module with a brand new one but here is the clincher!!! The window/lock module has to be PROGRAMMED to the vehicle for it to work!!! What a bunch of crap. I called around and got estimates from $50 to $100 to program it (a 15 minute job). $50 is not too bad so he will have it done there.
The problem is that Car manufacturers charge about $1800 a year to access their database for programming files. The equipment to do it also costs a boatload. The Lawmakers need to do something actually useful and put laws through that if a company makes vehicles with computer programs and updates, that it needs to be FREE or very low cost for all repair shops to be able to work on the vehicles.
With computers controlling most of the body functions now, it is actually easier and cheaper to WIRE the vehicles. For instance all functions of a drivers module (ie door locks and windows and etc), can be sent to the body computer using a single wire. Before this, a drivers window switch had all the wires from the other doors passing through it before going to the other door buttons and etc.
The problem is that if it is cheaper to do this, you don't need to charge to update or program different modules to work when they go bad.
Forward this letter to CONGRESS LOL LOL LOL

Hi Dennis,
I don't believe this is entirely true. I'm not intimately familiar with automobile computers but I do know a bit about them in general. Granted much of the executable code on these BCMs, ECMs etc must be read only, there has to be some writeable areas (at least e-proms or flash memory) to store error codes etc.
I'm wondering if with the truck's electrical glitches some bad program code gets generated? Here's an example. Let's say the BCM is "programmed" for a particular body style (two or four door) and installed options (side airbags, Onstar etc). This stuff would have to be factory programmed and remain unchanged during the life of the vehicle. What happens if because of the crappy grounds on the truck, the shorting fuse blocks and other electrical gremlins, these prom areas get smoked? Either they get changed to non-comprehensible codes or literally do fry from a voltage surge?
Here's a 'thought' of where I'm going with this. I have no ideal how close I am to how these computer systems work, but I have to be in the ballpark. Let's say there is a programmable longword, (32 bits) in the BCM. Each bit represents whether some elecrical subsystem gets power depending on the vehicles options. If a bit is set, the option (horn, airbags, windows, door locks etc) get power. The eprom gets programmed at the factory. Life is good, up to the point of a voltage surge, faulty ground or disconnecting connector socket, buring up blower resistor etc. This causes a voltage spike which fries or reprograms the eproms on the BCM. In short, bits get flipped or cleared. Now you have power being sent to wrong circuits at the wrong time (possibly tripping other error codes) or causing really weird and unexpected results, (the kind of weird stuff people have been reporting on this truck like turning the radio on causes the windshield wipers to work).
It also explains why sometimes disconnecting the battery can work. If the eproms remain ok, and just weird error codes were generated, disconnecting the power would allow these codes to reset and things would be ok until the next glitch.
Of course you don't suspect this so you take the vehicle to a dealer. They read the scrambled codes and deduce that "the BCM is bad" and happily charge you for replacing a perfectly good BCM. When the problem happens the next week, they say the BCM is bad again, and again, and... the Colorado/Canyon becomes the gift that keeps on giving... to the GM service departments.
In the meantime there are the real electrical and mechanical problems that crop up that could cause the whole thing. The bad grounds. The poor electrical connectors like on the blower resistor. The crappy CD player that can't read half the CDs you put in it. In other words, just poor GM design and lack of quality. These things fry and potentially start the ball rolling and the whole electrical system becomes unstable and unpredictable.
Otherwise how can you explain some of the weird things people have reported? Just weird stuff like, "I turn on the radio and the lights go off" or what was that last deal a few posts ago, "I turned the ignition and the truck wouldn't start. When I turned the key off it started cranking". How else can you explain weird stuff like that other than a computer controlling everything getting scrambled? How else can you explain just letting it sit with the battery disconnected for 6 hours "fixing" anyhing? Obviously something elecrical had to "clear" for this to sometimes work. Why doesn't to work all the time? Because all these problems probably do cause things lik the BCM to eventually fry.
I've been following these reoccuring problems with the Colorado/Canyon since 2007 and after this much time, that's my "theory". The pattern makes sense, at least from a computer standpoint, but again, I have no cluse if I'm all wet with how they work in vehicles.
If what I'm saying is somewhat true, there basically is no way to "fix" the vehicles short of ripping out all the electronics, electrical system and computers and redesigning them. Every ground would have to be checked, scraped and ensured of a good contact with the body. All underperforming parts like the electrical connectors on the blower resistor and frying fuse blocks would have to be replaced. The alternator would have to be beefed up. The list goes on.
Now I think you have an idea why GM will never acknowledge the problems with the truck. There were too few of them sold to justify such a huge expense just to satisfy so few customers. Much better to write off the truck and their owners, (especially when the only customer that really matters is their CEO Obama).
So GM writes off the truck and the owners, with one exception. Why pass up on all the lucrative repair money? So they invest to have "Peggy" prowl the forums, "appologize for your frustrations" and try to drag the truck owners to the nearest dealership so they can get their commissions.
The bottom line on the Colorados and Canyons is pretty clear. Get the truck working the best you can and dump it. If my scenario above is correct, the truck will never be "fixed". It will continue to be a money pit. You don't need an extra weird electrical problem every six months that costs $500-$1000 on average to fix on top of the normal expenses on an aging truck. Trust me, I know. I really loved my Colorado.... up until the fourth or fifth weird and expensive electrical problem.
There are enough vehicles out there like the Toyota Tacoma that do the same job. Toyota and the others stay in business because satisfied customers still mean something to them, where GM depends on government bailouts and the Chevy Volt as their future. (So what if they don't work as advertised, Obama is the only one they need to impress).
I finally gave up on my Colorado but still follow this thread. Hard to believe it is over 600 posts. And still, every week there is somebody new that finds this thread with the same story, window/fob (or some other weird electrical problem) and with the same, "the dealer said they never heard of it" reply.
What else can be said? GM= :lemon:
Before 1996 (OBDII), when someone disconnected the battery. The codes and the small amount of learning data were lost. A few drives and restarts re-established the learning curves. Now with OBDII and beyond, the technician has to use a reader to clear and remove learning curves (fuel trim, shift data, etc), from the ECM or Body computer. Usually by clearing the codes by a reader it also flushes the learned data also. We always caution the customer that your vehicle may perform slightly different for a couple hours or less after clearing codes. Most are unable to notice a difference though.
Every time you turn off your vehicle (as of yet), the computers shut down except for this small kept alive memory. When you turn the key back on, the computers have to initalize and start reading the burned in instructions to execute from ROM. Therefore, (as of now), it would be virtually impossible to execute wrong code including a virus or for the existing computer instructions to get corrupted. Remember, the instructions are contained in ROM or "Read Only Memory". Yes the computers look at the RAM area for data that is contained there but no computer instructions are in this area.
With PC's and Laptops, this is a totally different story. When you turn your computer on, the first thing the processor does is to read BIOS for the instructions to access the hard drive. Once it starts reading the hard drive, it is picking up computer instructions on how to execute Win98, WinXP, Win7, or a host of other operating systems that you as a user can install on the hard drive. This is where a VIRUS loves to be. Malicious code can be written to a hard drive that replicates itself on CDROMS, FLOPPY drives, Memory sticks, Internet programs, and etc. This code can be carried to other computers and cause the new computer to write these instructions on it's hard drive and continually replicate itself to other computers.
Yes, a trained technician can FLASH a new ROM onto a vehicle engine computer or body computer. However, this is only allowed if there is an UPDATE available from the manufacturer and it takes special tools and usually a $1800 a year fee to do these operations. So dealerships are usually the only ones that are able to do this. There are also safeguards when programming that checks the "Checksum" at the end of programming to see if the code installed matches exactly; otherwise a message pops up that says "Programming Unsucessful".
When I had my window/lock problem, all the other functions on the body computer for my Colorado worked perfectly. The radio would turn off when the doors were opened. The dome light would go off at night when the key was inserted, and all the seatbelts, low fuel, alarms, and etc worked flawlessly. The only thing that didn't was the drivers door window, and the locks. The parking lights would flash with the fob but no lock activation occured. This told me that the body computer was acting normally and was intact. Yes Murphy's law is still possible. The body computer could get corrupted. But simply a turn off of the vehicle and a restart would re-initalize the computer sequences and would be ok again. If you noticed, quite a few people tried disconnecting the batteries and etc and it didn't fix the problem. Some said it did and others said it did not help.
With all this said, I am only human and maybe someone can show me that I am all wrong. If so, I am happy with that also.
Catch you later, Dennis
Again, I have no idea how 'code' is derived in vehicles but I do know a bit about computers and coding itself. You're making the assumption that the ROM code is "flawless". I have seen really weird things happen with low level code, "programming errors" that are so subtle they are nearly impossible to find. They are nearly impossible to reproduce because the confluence of circustances that cause them are so obscure. It might be an obscure piece of code that runs but whoever coded used a case statement that doesn't address that particular condition, or there is a missing return or something, no error handling and the code thread falls through executing some other instructions out of sequence that screws up something else, which in turn screws something else up until the BCM is hozed. Maybe when the ROM was being written somebody coded an incorrect label and the code thread shifts to some nonreadable data area and the BCM is hozed.
Right from the get-go these trucks had weird electrical issues. Here's an example, I've heard similar storied from a couple of other owners... When I got the truck I wanted to make sure the door key worked. I tried it in the lock and the horn started to 'toot' lightly as the door unlocked. A few seconds later it started the "somebody is stealing me!" scream. I hit the panic button and it stopped. Kind of shaking my head I looked at the GM sales reps, and asked what the truck was doing. Sheepishly they just kind of shrugged like, "Ummmm, that's the new... ahhh, horn-test system I guess?" They had no clue, we kind of figured it was some kind of "new thing" that would be explained in the manual. Of course there was nothing, so maybe it was something "undocumented"? Perhaps, but my guess is it was the first sign of some weird programming error.
The more I think about it, the more I have to think the majority of these problems have to be computer and/or code ("programming code") related. The reason I think this is because some of the weird electrical stuff would be hard to explain if it was simply 'physical' problems like frayed or shorted wires. Things like that don't usually "get better" or heal themselves, but computers can and do. With a computer a weird set of circumstances and poorly written code can can screw them up and likewise a weird set of circumstances (disconnecting battery leads, putting the key in the ignition at the right time, turning on the lights, some kind of sequence of inputs) can heal (reinitialize/clear) them.
How else can some of the weird stuff be explained like turning on the radio locks the doors or whatever. I guess it could be physical like shorted wiring, but it sure as heck sounds like poorly written process control code.
Again, I'll be the first to say I may be completely off base and this stuff and what I say is impossible, but for a moment let's say it is possible... Say some highschool dropout at GM was writing the BCM control code and was still stoned from lunch and kind of forgot a return instruction before sending the code off to be burned as ROM into 16 million BCMs. Everything looks ok and the problem doesn't get discovered until that particular piece of code gets executed, something like, the lights have to be off, the radio on and the air conditioning on when the truck is turned off and the key left in the ignition with the dome light left on for over 20 minutes. Maybe that piece of code gets executed when the BCM realizes the dome light is still on and the code is supposed to turn it off. It does, but rather than return to wherever it is supposed to go, the thread falls through into "the twilight zone". Somewhere along the way it turns power into the drivers window relay and shorts out the little chip in the drivers window/fob circuit. This causes the battery to drain and with the low voltage fries something else when the key is put back in the ignition and the BCM fully powers up. Like I say, just some weird confluence of circumstances that happens every 6 weeks to 6 years. In the mean time, add in the poor grounds and wiring connectors and... you have a nightmare to solve.
Let's say that scenario has even a grain of truth. What is the "proper fix"? Troubleshoot and locate the obscure problem in the code, do all the testing and debugging, then what? Produce new BCMs with the corrected ROM code? Recall all the existing BCMs in all the trucks? And if the code is written so crappy in one place, what's not to say there may be other code glitches that haven't been found and would be burned into the new BCM ROM anyway? For so relatively few customers? (The Colorados/Canyons were not big sellers). Factor in a company going bankrupt on top of this, would you elect to have a recall? Incurr all this expense? Forget it, just donate to Obama and get tax money to stay in business instead of relying on satisfied customers. We're back in business again, just sweep the Colorados under the rug except for the lucrative repair money... The guy that programmed the Colorado BCM was probably promoted to doing the electrical system on the Volt...
Anyway, that's my rambling thoughts. I guess it really doesn't matter since GM is obviously not going to address the reoccuring problem that doesn't exist. It really would be interesting if there ever was a definitive answer but I doubt it will ever be determined for sure.
Because of the Japan tsanami wiping out the competition, GM actually make a 7 billion profit.
Of course the auto supply chain from Japan is back online now and next year projections for GM next year are grim. Their stock is still in the tank after you and I bought the company for Obama but does this concern them? No.
While times are good and they have this windfall of money, do you think they might consider paying off their government loans? (Eh-eh, are you high?). Do they try to fix the electrical system on the Colorado? (You really are stoned if you might think so, why kills such a great repair cash cow).
No.... they decide to give all their union employees a $7,000 bonus! (Way to go Peggy, spend my tax money well).
GM= :lemon:
I measured the draw at 65ma which is ok- anything under 100ma is good. However upon making and breaking the system ground, the power door locks turned on and activated a couple times during interruption of current flow.
When I went to open the doors on the vehicle, they were locked and the keys were inside. Thankfully, the drivers window was wide open. That is one thing I generally do when working on a vehicle is roll the drivers window down. I just got in the habit of doing it over the years and good thing I did.
The interesting thing is that the computer system called for the locks to activate when the computer system was unstable. Upon shutting off the vehicle and restarting it, things turned back to normal.
So, end result is that you and I are both right. A glitch can screw up a body computer and re-initalizing the computer straightens it out (at least untill it screws up again). LOL LOL LOL
If you have some time before surrendering it to the dealer, try this - take the driver's door switch out but leave it connected. On the blue connector there is an orange wire. This should have 12 volts direct from the fuse. Try to get a probe from a voltmeter into the back of the connector and put the other probe into the ignition switch (or another good ground) and see if you have a solid 12v. With the meter in the connector, try pressing on the lock and unlock to see if the voltage drops to 0.
If it drops (and nothing happens) you most likely have a problem between that wire and the battery – probably the fuse connector in the fuse block. Probably the easiest way around this is to run a good 12v line with an inline fuse to splice into the orange wire.
What I did was jam some copper strands in with the fuse legs, making the fuse legs a bit beefier and thus a better connection – it worked but I don’t know how long it will last – been working for a year so far.
Good luck!
Well, I wonder if it is a "Chicken and Egg" kind of thing. What if there is something like a poor ground which causes current to backfeed to a different ground is what causes the BCM "glitch" in the first place. Perhaps it fries the BCM or just gets it to throw false codes. The dealers happily replace the $400 dollar item because it is "bad". Maybe it is, maybe it's just the bad ground and confluence of circumstances which fried the BCM but may not happen for another two weeks or two years.
Possibly it goes the other way around. Perhaps these confluence of circumstances (poor programming code/errors) causes the BCM to not fully shut down sometimes and constant power is applied to the door module which burns it out and drains the battery. Maybe because of the dead battery the BCM "resets" in some way while someone tries one of the voodoo tricks like touching the leads together, cleaning all the grounds, sacraficing a virgin over the radiator or whatever and the window works, so whatever they tried becomes a 'solution'.
I sure as heck wouldn't want to troubleshoot the electrical system and component computer code to find a definite answer... and apparently GM doesn't want to waste the time either. It's just more lucrative to claim "Hecky-darned, imagine that, it's a bad BCM again, bummer for you, here's the bill... again" and collect the fee. Obama needs those reelection donation dollars rolling in!
My power door lock,window problem corrects it self. It goes off and on with out me doing anything. It started just a couple of years a go,around the sane tine My right blinker shorted out. thats the only problem I had so far, however. I had changed the battery after 6 years and the problem went away for the better part of a year, but now it,s back.
I love my truck an I plan on keeping it .I also have a 2010 toyota camry, that needs tires after only 20,000 miles and a lot of call- backs.
when i bought the camry I watched as the toyota dealer changed the frames on the tacoma,s because of sever rot.
After I was seeing how it comes and goes,i am thinking it,s a computer glitch .
Power windows, power doors, myriad vanity lighting and things have /always/ been sources of problems. Now we are demanding a whole new generation of problem-creators like bluetooth integration, navigation systems, drink chillers etc that will cause an additional layer of problems. If you want a more reliable, or less-costly vehicle to buy and repair, then buy them without all of the gadgets. Otherwire face the fact that they will cost you extra money eventually, no matter how well designed or reliable the component might be. Cars should have a body, seats, doors, engines, wheels and saftey lights. All else is essentially superfluous.
Ummmm, no. I don't agree with the "every vendor is the same" excuse. There is an obvious, reoccuring problem with the electrical system on the Colorados and Canyons that GM says "they never heard of" as they size up your wallet.
Perhaps you don't mind paying for something and not have it work, or paying for repairs that don't actually fix the problem but this goes way beyond that. You expect tires to wear out. You expect an alternator or starter to eventually go bad. You don't "expect" to have intermittent electrical failures of critical components like the battery, brake lights, windows, wipers, headlights, panel lights, fuse block not to mention the CD player, blower, blower resistor. How many vehicles have you owned that required a head replacement because of poor engineering?
True, every vendor can turn out a turkey product. What it comes down to is if they stand behind their product, not whether they stand behind Obama to stay in business.
GM= :lemon:
Ever try to change the rotors in a Colorado or Canyon? You wanna talk about poor engineering. If I had known of the cluster**** they made of the wheel/braking assembly, I would have NEVER bought my Colorado. If you have never seen it, check it out online. It's a nightmare!!!
The brakes were the first problem I had with the truck though. The truck was about 3 days old. I made a right hand turn and heard this horrible and loud metal on metal grinding kind of noise. Only when I turned to the right. So I take it back to the dealer. The tech that had to work on it was kind of miffed, he says, "You shouldn't even bring the thing back in unless it has at least a thousand miles on it". Huh? Not. I got the sales rep, raised hell, and I'm driving in circles in the parking lot with three guys in the bed and two listening from outside to the grinding. It turns out there was a big bur on the rotor that was grinding.
The most amusing one these morons did was to the steering. I forgot what I brought it in for, maybe it was the head replacement. Anyway, I'm driving out of their parking lot, making a left turn onto the highway and the steering wheel locks up and I'm aiming back into the oncoming lane that naturally has a semi barreling down on me. I tugged the wheel. Still locked. I yanked it and it came free and I steered out of the semi's way. I do a 180 and head back into the dealer. Turns out the monkeys managed to get a wire wrapped around the steering column. When I turned left it tightened up and jammed so the steering wheel couldn't turn back to the right, (that is until the wire broke. At least they didn't charge me for repairing their stupidity that time).
This was also a couple of years before the whole fob/window/battery thing began to manifest itself.
I can't say it enough... GM= :lemon:
Any ideas ?
Also the heads go bad, the alternator is undersized, the blower motor and resistor fries, the CD player fails, the list goes on. Your best bet is to sell the thing before you sink more money into it.
It really is a shame because the truck is a nice concept. It really would have been nice if GM had engineered it like a vehicle rather than money maker for their service department.
I had tried that solution but there was too much magic involved to answer the question why it should have worked - didn't work for me. Check out my post #638 - this worked and the answer was a weak fuse clip in the fuse box. You may consider running a hot 12v line with an inline fuse direct to the drivers door switch to bypass the faulty connector. In any event, let us know how you make out.
Good luck!
This is absolutely true. There is absolutely nothing that you can count on except that GM has no solution except to throw expensive darts at the replacement dart board.
I've been active on this thread since there were about 50 posts, that was 600 posts ago. There have been many proposed causes and possible solutions. Some work, some don't, some work for a while. I can tell you though, there is nothing conclusive as to cause or repair. My guess it that there are multiple possible causes. Maybe it's a pinched wire or bad ground, and in amongst replacing the BCM the Chevy ape manages to bump the wire and it works and they declare the bad BCM is the $400 dollar magic bullet. Then two days later you hit a bump, the window goes out, you bring it back, they give you the song and dance that the BCM was "bad anyway", and replace something else. Maybe it works, maybe it doesn't. Maybe a voltage spike from the bad wire or defective fuse block burns the window module but the wire unkinks because it warms up and the obvious problem was the window module not the BCM... until it turns cold and the wire gets stiff...
I really liked the truck, no question about it, but... trust me, it is NOT worth chasing. You are much better off selling the truck and getting something else... unless you don't mind a window you can't roll up in the winter, or a five cylinder engine that has no compression because of the defective head, or tail lights that may not work, or a CD player that can't play CDs or... you get the idea. It's a personal choice... my money, I hate to say it, went to Toyota. I wish it hadn't but I've given away enough of my money (and Obama has too), to a company that does not support their products.

I remember them saying that there was something odd about the circuitry with the module, like the driver's window was on a separate power run or something. In any event, they trailed it down to power coming into the module and nothing coming out. I guess there is some sort of circuit chip in the module that directs power. Perhaps power surges, or more likely low voltage causes it to fly or flake out, draining the battery and malfunctioning.
It's an expensive piece to replace, something like over $300 bucks, but I'd be worried about trying to get one second hand or from a junk yard because there is no telling if that piece is bad.
After all these years you'd think GM would have a definite solution. It's a shame because the Colorado is a good concept for a small truck. It's just a shame GM does not support their products as much as Obama's reelection funds.
After reading your post, I couldn't believe that I had exactly the same problem,
the motor would struggle to drive the window up or down and that's on days when the motor wanted to run. On bad days you would only hear a clicking sound when the the switch was used in any direction. Anyways, I did what you did, cleaned motor as much as I could, put everything back in their place, and it worked!
I am so happy, I have been dealing with this problem for over a year and your post hit the jackpot.
Thank, gthfish
I'm so glad to see that you've been able to find a way to solve the issues you had been having with your power windows, especially with the hot summer months on their way!
Wishing you many happy and cool miles,
