Not sure if this will help, but....
I had to slam on the breaks 'cause of an idiot in a van3 years ago. All of a sudden my 05 was running rough and backfiring. Got warning notice on dash. OnStar said ok to drive but to take right to dealer. Dealear did a diag and there was a problem with the device that adjusts the valve timing. The computer changes valve timing on the fly I think. They changed it and my gas milage went UP!! I was getting 14/19. Now, and this is NO BULL.... I'm getting 17 - 18 in town and 24 to 25 on the open road. Drove to Fla from NJ and back twice. Even running at 75 mph I was seeing 23 mph. I"m happy - Oh, it's the I-5 engine.

I have an 04 crew cab with the exact same passenger door problem. If you bang on the inside of the door or pull on the glass it will work. Any help is appreciated! I hate to buy a new window motor and find I still have the problem

I just changed the original battery in my 04 Colorado and now the driver side window does not work. The passenger side window and all door locks still work. Quite odd. I will scream if the window motor went out because of a battery change. I did hear sounds (like motors moving) when I connected the new battery. Anyone else had this problem? I am going to try to disconnect and reconnect the battery later.

I have a 2004 colorado crew cab with the same problem with the locks and drivers window. On dec 26th I decided time for a new battery and which I replaced and that's when this problem started. Could this problem come from just disconnecting the terminals?
Well thanks to HopeGMC it's working again. I took it apart and looked at everything and things looked OK so I tapped the relay and put everything back togather and wow it worked. A GMC/ Chevy repair......
My hats off to HopeGMC thanks alot. What is the BCM and TSB. Just for reference I might need later. Thanks again... ZIPY
 
Hope this helps. This was a year ago for me. the relay is like a small aluminum block on the circuit board. Also spray the connectors when putting back togather. Go back and read this on page 15-16-17.

well i dont know i if you have fixed this problem yet but i have had my 04 do the same thing all the others work but not the drivers window, after a lot of trial and error i got aggrevated took the posotive cable off the battery and left it for about two hours and like a miracle it worked again, since then i have had to unhook the battery several time to put in upgrades and little trick (stereo, amp, speakers,etc) and everytime the wondow stops working, so i will unook the hot cable for about 2 hours and pretty as you please it will work again, if you have this problem again try this, from what you described i about 95% sure this will fix your problem. good luck

I also am having the same issue..I had to put the brakes on pretty hard a few days ago and now the engine is running very rough. This has happened before but it worked itself out..but recently it has gotten worse and will not work itself out. Having it towed today to get looked at.

I removed and tapped the PWR/WNDW relay from the box in front of the battery, which I am assuming is the relay you are talking about. If not, let me know. Sprayed and replaced and no change. Thanks for the input. I'll try anything that sounds like it has a chance. Next, I am going to try disconnecting the positive cable for a couple hours as tyrod is suggesting below.
Thanks Again!

Tyrod-
Thanks for the input, but this didn't work for me either. I left it disconnected overnight and reconnected it in the morning. No change. No driver side window or lock. The passenger side window will still operate from the driver side, but nothing else. Other thoughts?

Please refer to my previous postings #197 and #208. This is a very common problem with Chevrolet Colorados. Hopefully, these will help.
