Thanks Bitsmasher, the thread has gotten so big that it is hard to find previous posts without the message #. Yes, that is the way to fix circuit problems by testing the circuit with a load. So many people just probe the connection and verify 12v without operation or load. Seen it time and time again being a auto-mechanic. You have to load the circuit to test connections and voltage availability.
Thanks

I just traded the truck in after fixing several problems myself. I was fresh off of a new vehicle purchase and saw a post from another. I came to this website originally to find a solution to problems with a truck that I really loved. I certainly have not spread doom and gloom. I have merely expressed my concern with others purchasing Chevy/GMC products. Some people have Chevy/GMC vehicles with no problems. But most have had the same issues that all of us have experienced. Many ignore the weird electrical problems, due to the cost of repairs. My point being, if I or no one else complains, then no one will hear the issues and the companies will continue to sell bad products to unsuspecting people. No one should have to research and find solutions to problems that should be fixed by manufacturers. Please don't take my posts personally and attack me, when they (Chevy/GMC) are at fault.

#664 of 671 inoperative door locks and drivers window won't work. by tmallett

I have a 2007 colorado and I have had nothing but problems with the electrical system. The first was my blower motor speed control on the a/c. I replaced the module under the dash behind the glove box. That worked for a few days and then it quit working again. Then I ordered a new wiring harness that connects to the module and runs on up under the dash. It came with a new module. That has taken care of that problem. Then two days ago, I replace the original five year old battery and when I put the new one in, the drivers door window would not go up or down and the doors wouldn't lock or unlock with the key fob or using the control panels on the doors. I tried to reprogram using the manual and that didn't work. That's when I got on hear and found the same problem had been fixed by removing the control panels and puting the bioelectric grease on the plugs and re-installing everything. I thought no way is that going to fix anything. Tried it and it works. It may have even gotten rid of some other little gliches I was having like my tire pressure monitor flashing on the messages. I did have the truck reprogrammed about six months ago and it has never been as responsive as it is now. This little truck runs like a scalded cat and will slip the tires when it shifts from first to second gear if you stay in it and don't back off the gas. I love these little trucks, I just wish they didn't have so many elec. problems. I now have about seventy four thousand miles on it. G.M. obviously is not going to help us, so we just have to help each other. Thanks for all the info. that everyone put on here because it sure helped me out.

I also had a chevy colorado that I loved as a matter of fact it was also an 07. Had 2 chevys befor it I loved even more, BUT with all the problems with this truck (Mine was the stripped down version, NO electrical "doodads") and NO help from the JERKS at the dealership (Randy Wise Chevrolet Milan Mi. THE WORST DEALERSHIP ON THE PLANET!!!) AND even less help from G.M. (Govt. Motors) It will be a LOOoong time befor these folks see ANY of my $ again!!!

You must be like the last human being on the planet that had a Colorado, the rest are in the junk pile on their way to China to be sold as scap to Toyota so they can be turned into reliable vehicles.
 
This thread has been dead for about 6 months.
 
Just about everybody that was on this forum loved their Colorados or Canyons, but the stories are pretty much the same, endless reoccuring electrical problems, no help from the company or dealerships (with the exception of them helping themselves to your credit card). Pretty much everybody that was here moved on to other vehicles and manufactures.
 
Give it time though, you'll get Sarah, Camron, Hewy, Dewy and Louie from the "GM Customer Care Club" or whatever it is to try and steer you into a dealership so you can get your wallet cleaned out and they get their commissions.
 
My advice, get rid of the truck before you have other expensive surprises like the tail lights not working, the head neading to be replaced, the radio failing etc.
 
It really is funny, the one reoccuring theme with the truck is when the battery is disconnected or drained. After that, the electrical problems with the vehicle are endless.
 
Best of luck to you. If you don't already, sooner or later you will understand...

It's not a coincidence. I have an 05 Chevy Colorado also and had to disconnect the battery. When I hooked it back up...no power door locks and the driver side window would not work. If you search this on the internet (I'm a master internet surfer), you'll see it appears to be a common problem with the 05 Colorado specifically. Everyone says it's the BCM and suggests "tricks" to fix it by disconnecting wiring harnesses, touching battery cables, waiting several days, weeks, months, etc. None of it worked for me. Taking it to the dealership to be fixed or driven through their showroom window.

This door lock and window issue is all over this thread. Disregard all the general "don't know what they are doing comments". There are basically 3 ways to fix this issue. Remove the plugs off the door switch module and apply di-electric grease to the plugs. Replug back in and see if the problem is resolved. Check for a good 12v feed that powers the door module. You may have to test this by applying a 12v load such as a headlight (2-3 amps), to the circuit to make sure you can pull a good 12 volts through the wire. There have been problems with the fuse block fuse connection for the door module loosing power at that point. If the previous 2 methods don't work, replace the door module (on ebay or amazon for about 40-60 bucks.)
 
Disconnecting the battery and or touching battery cables together don't do a thing even though it may appear to resolve the problem as it is an intermittent problem. I fixed mine 2 years ago with di-electric grease.
 
The body computer is NOT corrupted or anything as every other function of the body computer still functions. All other methods of weird stuff are just "Shade tree mechanics" that don't know what is going on.

Finally sold my Colorado as I couldn't get good mileage around town. Was able to pull 23-24mpg on highway, but might as well drive a full size pickup that gets that TOO.
 
When sold, everything functioned like factory new with no check engine light either. I was happy with the vehicle except for poor stop and go mileage for a 4 cylinder engine. In my opinion, the 4 cyl engine had adequate power. Some people bitch that Colorado's were underpowered but it didn't seem all that bad to me.

1. The passlock sensor is a component within the ignition switch, so you buy the entire switch:
 
part # 15795321
 
2. Not sure what you mean by "timing sensor". do you mean camshaft positioning sensor (that is, valve timing) or do you mean something related to ignition timing?
 
3. Part # 12588097
 
IF you mean camshaft sensor, that part # is: 12584516
 
If you mean ignition timing, that is not done by sensor. It works thusly:
 
IGNITION COIL/MODULE
 
Each ignition coil/module has the following circuits:
An ignition voltage circuit
A ground
An ignition control (IC) circuit
The PCM controls the individual coils by transmitting timing pulses on the IC circuit of each ignition coil/module to enable a spark event.
 
The spark plugs are connected to each coil by a short boot. The boot contains a spring that conducts the spark energy from the coil to the spark plug.
