TBunch: I have had the same problem with my 2004 Colorado. It occurred 3 times in the 5 years I have owned it. In the manual, under "passlock", it states that you can wait 10 minutes and try to start it again and this works for me. However, I would like to find an answer to the problem. Have you spoken to or written to anyone at Chevrolet to get an answer? I did take it to my dealership 6 mos ago and they put it on the analyzer and then told me I should replace the ignition switch module to the tune of $400+. I chose not to do that. The manual also cautions you not to leave the starter engaged once it starts. I have noticed at the times this happened that the starter seemed to stay engaged even though I released the switch key. This may have something to do with the passlock disabling the fuel system, which is what it does. HCoombs

I was waiting for the weather to get better as this truck is my only transportation I thought I would ride my harley while I get my truck fixed. I told my wife to get it set up to take the truck in with in the next 2 weeks. On 4-7-09 it was a warm afternoon and I stop and got gas got back in the truck and went to roll down the window and it worked I sat at the stop light rolling drivers side window up and down 10 times like a kid. When I got home and and used the key fob to lock and un lock everything is working????? Has not worked since Nov. Now all the sudden starts working I am not going to mess woith taking it back into the dealer I am just going to wait until I change battery or what ever. Dealers act like they never heard of this and in 2 minutes I can google and find many who have had the same symptoms. Just glad it started working.

I posted this same problem, last year. When the weather was warm, everything worked. When the weather was cold, the power door locks and driver's power window would NOT work. Yours may continue to work all Summer, but when Winter returns, the problem will reappear. The only permanent solution is to replace the driver's side power window/door lock switch assembly. If not in warranty, it's very expensive. This is certainly a frequent problem by many Colorado and Canyon owners, but GM won't acknowledge.

Yes I re call reading that. I am keeping print outs of all I find on this problem. Is there any programing involved with the driver's side power window/door lock switch assembly? its not clear to me I think I read something about that?

NO programing required. It's a very easy swap-out, so if you have to pay for replacement, I suggest installing yourself and saving the labor cost.

tbunch: in my 2004 Colorado Owners Manual, Pg 2-17, it implies that all of the Colorado's are equipped with the passlock theft deterent system. the system enables fuel to the engine if the ignition lock cylinder is turned with a valid key.
If a wrong key or the cylinder lock is tampered with, the fuel system is disabled. It also states 'remember to release the key from START as soon as the engine starts'.
 
(i still have a feeling that possibly the starter solenoid (sp?) or something in the start circuit is causing the starter to stay engaged too long. I believe that this will enact the passlock.) HCoombs

The window/lock/battery issue update by snaproll1

I think I started this thread way back when or at least this is where I posted the window/lock/fob/starting/battery problem a year and a half ago.
 
I've been following the thread since then. I've seen posts to the effect that it's the door module on the driver's side and bad grounds, but I really don't think that is the issue. When I started having the problem, I found a few posts on the net with a bunch of silly stuff people were hearing from their dealers. Things like running both more than one window at the same time was "the" problem, yada, yada.
 
Basically a lot of folks were saying that their dealer had "never heard of the problem before", yet I found several posts of the exact same symptoms. I found if I removed the door module connector and plugged it back in, everything would be fine for a few days. My dealer said that was absolutely crazy, at best it was resetting something in my BCM that 'fixed' the problem temporarily. My dealer said, "Never saw this problem before, and whatever you read on those internet posts are garbage..." The said the BCM tested bad, that would fix the problem for sure... and the problem happened the next day, truck wouldn't start, wouldn't turn over, dead battery. So they took it back in, farted around with it again and said the two and a half year old battery was the problem and... "Oh by they way, there was a service bulletin on your fuse block, which yours was burned... and we replaced that for free!"
 
Uh-huh.
 
That was about two years ago and I haven't have a problem with it again. Here's what I assumed happened. There is some defect in the fuseblock that fried the BCM, battery and possibly the heater blower motor. The day after they got done 'testing' all the stuff the blower resistor fried as well, "just coinincidence" according to them, (fried the very NEXT day???). So I think this improperly designed fuse block shorts out and causes all kinds of electrical problems with the truck. Since I had it replaced, (and all stuff that mysteriously fried in the space of about a week), I haven't had a problem since.
 
Well, except for the head replacement because of the soft valve seats. Luckily they covered that with no issues and the truck has been running ok since. I have 99K miles on it and it's a 2005. One other weird thing, I don't tow much or often, but I've had the U-Joints in the drivetrain go bad. I replaced one set a year ago and they're sounding like their going again, a metalic 'clink' like a pipe rattling every now and then. I'm still getting about 20MPG with the truck, which is why I bought it, but I'll tell ya, this is the last time I "buy American" until these bailout buddies start building reliable vehicles or honestly start backing them once again.
