I have a 2004 Colorado Crewcab that had "that" problem with the power windows not working within 6 months of purchase (can't recall if door locks were affected). Chevy replaced driver door switch/circuit board assembly under warranty - great! Had to replace battery 18 months ago, but no big deal. On February 5, 2011 (58,000 miles), the truck would not start. Would crank, but not turn over. Disconnected negative cable from battery for 15 minutes, reconnected and truck started and ran fine. Upon leaving that location, noticed that door locks would not work from console or fob, and driver's side window as well. Got home and called my mechanic (very trustworthy) and he said he would check it out. In the meantime, I found this website and read all 300+ posts. When my mechanic told me that he had tried everything he could, including taking apart the switch/circuit board assembly and inspecting/cleaning - cost to replace $250+, I mentioned that I would try and find a replacement at a junk yard - well, that didn't work (and one business told me that I was the 2nd to call for that part in a week). I then tried some of the suggestions on this board - + battery cable disconnect, add star washer to ground, etc. Nothing worked. Found one other website/board with a suggestion to take off the cables from the battery and short them together for 3 hours to discharge capacitors. I am an Electrical Engineer, and while I understand the concept of capacitor discharge, I struggled to short the leads together for fear of potential other problems. Anyway, did just that for 30 minutes, unhooked the cables and left alone overnight. In the morning, hooked up the cables to the battery, waited a couple of minutes and started the truck with no problems. Let the truck run for a minute, pushed the "L" on the door lock switch and the door locks closed. Then tried the driver's window and it worked. Ran the truck for 10 minutes and shut it off. Opened the lock with the switch, then opened and closed the door and locked with the fob. So far, so good - I just wonder how many "computers" are a part of a modern vehicle. I think there are 2 just with the door circuit board.

my wife could NEVER understand why I would order/purchase my vehicles as "PLAIN JANE" as possible. The old saying holds true "The more you have on a vehicle (electrical doo-dads.) the more things you can have go wrong!"

Ok Im so confused, I have owned two 04 colorados the first one had for 2 years, only had the blower resistor problem, sold it only because of family got bigger needed a 6 seater. any way now I dont need such a big vehicle and purchased a second 04 colorado. well right off the blower resistor went fixed it, then the control for defrost stripped the gears. And I totally love my Colorado. Well now the whole power window, power lock thing is totally screwing up. I have took apart tapped on rly 3 as mentioned. didnt work, took battery cables off cleaned post. cleaned under ground going to frame, re attached, no go. checked all connections. seem good. I can purchase a new window switch but dont wont to if not the problem. I would really like to know if any one has had this problem and a new switch didnt fix it! so confused, I have been a diehard chevy fan, and still am I hope the start stepping up and recognising, these problems.

I've had the window/fob/door lock thing twice. Keep an eye on your battery. If it goes flat, then you have the problem that Chevy never heard of.
One post a guy wrote that capasitors in the system needs to be discharged and shorting the battery leads (disconnected from the battery of course) fixed the problem. Never tried that one. Don't know if it will really work.
I feel your pain. It's a good little truck if it didn't have all these weird, reoccuring electrical problems that Chevy never heard of.

Wow i cant believe all the posts on this issue . I had the same drivers side window , inoperative door lock problem a year ago . couldn't figure it out weeks later it just started working although i hear beeping like my keys are in the ignition when I get out of the truck. Months later the cd player stopped working but radio worked, farther down the road my heater fan works intermittently.
Well today i left my flashers on drained the battery. Jump started the truck and now drivers side window doesn't work again and door locks or keyless entrydoesnt work.. Just for kicks I tried the cd player figuring whats the chance, Well i can now play cds again just cant use the window and locks!!!
I cant believe GM wont do anything..........I stoped buying Chevy years ago and figured i would give it a try again and nothing has changed other than they use our money to fund lousy service and products.

And don't forget the govt. uses your /my tax dollars to bale them out and make it mpossible for them (G.M.) to give out BIG BONUS CHECKS to thier "higher ups!" Thats why they don't want any recalls they gotta pay back the Govt!!

I removed all of my bulbs (headlights, turnsignals, and brake lights) coated them in electrical grease and reinstalled them all. This did indeed fix the problem that I was having, but since then a bulb or two has gotten loose three other times. Maybe in the 2012 owners manual then can put a bit in there to "snug" up your lights with every oil change to keep the entire electrical system from going haywire... Thanks canyon08 and sorry for the late reply to the board, but I have a relatively new electrial problem which is why I logged back in.
#396 of 684 ABS Fault on Rainy Days
Feb 23, 2011 (9:58 am)
My truck's latest electrical glitch comes about after it rains. I noticed this back in 2010 when I was having the electrical problems with the turnsignals/MPH gauge, but thought it was tied in with that; however, it is now happening every time it rains. Truck starts fine, goes into gear fine, but as soon as you're getting up to speed the MPH gauge goes to zero, it throws an ABS Fault code, and the transmission locks into 3rd gear and will not shift out of it. The problem is only rectified after driving for several miles, sometimes longer, at upwards of 3,000 RPM until I notice the MPH gauge begin to flutter. At this point I have to pull over, shut the truck off, and turn it back on. After the water is out of wherever it has gotten the truck acts like nothing has happened. As a lifelong Chevy man it is getting harder by the day for me to say I will never buy anything else, but as soon as I get this problem resolved the truck is going up for sale!

Glad that fixed that problem..electrical problems are the worst and seem to be a serious issue with this truck, too bad because I really like the damn thing! I'm popping a 449 code now...sounds like a vaccum leak but too cold and snowy to crawl under now, still runs fine. Recently, my fob works good for awhile then it seems like the truck isn't picking up the signal and it's only 5 months old..
