I have a 2004 chevy colorado extended cab and lately my drivers side window has been acting funny, sometimes working just fine and sometimes it just stops for a bout 15 seconds, then will start working just fine again. the locks work, and the mirrors work. and then yesterday i got in my truck, put both windows down, and drove about 5 miles. when i parked and tried to put the passenger side window up it didn't budge and so i waited hoping it was just the same problem as the drivers side window but nope... it wouldn't move. so i had someone pull up on it while i pressed the button and it went up just fine, then it worked fine for about 5 minutes then got stuck again. i don't know what is going on. but this morning it worked fine again for a couple seconds then just froze up again. i can hear it click on the passenger side door like it receiving the power its just not moving. ive been reading a lot of posts with people having electrical problems, i don't know if i should hope its electrical or the motors are going out. i don't know which is cheaper. any response is welcome.

Just found this after having issues with my 04 Colorado for a number of years. First incident was this: after shopping came out to my trucks wipers going and when I unlocked the door, the blower was on inside. This while the keys were in my pocket. Dealer replaced the BCM. Under warranty. Fine for 30,000 miles. Next problem: Go out to the truck, nothing works. Try to start, only thing that came on was the service engine icon on the instrument cluster. Nothing else. Dealer replaced the BCM again. $700 bucks gone. 3 weeks later, Driving the truck, filled up gas. Blower on while the keys in my pocket. While driving the truck to the dealer, the wipers turn on then stop mid way, the horn honks twice, the instrument cluster goes completely black then displays the odometer reading as 999999. Blower does not work, locks work, but when you shift out of park or drive it used to lock and unlock the doors, it does not do that anymore. Replaced the BCM again. They are going to replace the instrument cluster once they get it in. So far the dealers techs are dumbfounded on how this is going. Any other ideas? I am going to ask them to look at the fuse block. Just seems to be a lot of electrical issues with this thing. |

OK, so I bought a loaded 2004 4x4 crew cab colorado z-71 for my daughter, past owner told me had just put in a new battery, after one month all of the problems listed in this post with the exception of the blower began happening to her truck. So, I began to disconnect and reconnect every harness connector to try and trouble shoot this issue. FINALLY, last night as the no start no power no dash passlock battery good condition occurred once again my neighbor watched the dash while I wiggled wires yet again. and fixed it!!!!!!!!. From the battery trace the small ground wire to the inner fender, remove the bolt, remove the small retainer that holds the eye on the bolt. remove the eye connector, place a "star" washer on the bolt, reinstall the eye, place another star washer on the bolt and reinstall. Problem is resolved. no issues, door locks, lights, dash, pass lock all ok now

| I have a 2004 Ext. cab 4 wheel drive I5 Chevy truck and the problem I have is my check engine light has come on and will not go off even when you take the key out of the ign. The Chevrolet dealer checked for a code but there is none. HELP!!! | |

The 2004 Chevy Colorado is actually "Decepticon" technology, designed to create confusion and distraction amongst the human population, meanwhile, The Fallen wage their endless war against the "Autobots." Seems as likely an explanation as any you'll get from the Dealership.

Has anyone replaced their own Body Control Module in this truck? Mine went out once under warranty and now it has apparently gone out again. Several things that it controls no longer work like fog lights, door lights, door lock from remote only, cargo light, etc. Got the schematic and traced it back to the BCM... ouch. No warranty this time so I'd like to do it myself. It's easy to get to - 5 minute job as far as physically doing it but I don't know if there is any programming needed and I don't know where to get it or what the part number would be. I couldn't find it on rockauto or the gm parts site. My truck is the LS with power door locks and windows, etc. and I only seen the one without all of the power options... The one listed on amazon.com is about $138 but I don't know the correct part number for mine so I'm not sure it will work. Any advice out there? Thanks, Dennis

| I am new to this forum but since I have been reading the posts I have hope for my 2004 3.5L ext cab 4x4 pickup. I had electrical issues with radio not shutting off when the drivers door is open. The door lock chime does not work when the lock button is pushed and door is open. I took the vehicle in to the deal who claims the problem was in the drivers door wire harness and it was fixed. I presently have an Air bag light on all the time so I took the back door drivers side apart last night to trace out the wires. The black tape job that was around the wires was loose, I found one expose wire inside the door (I taped it). Where the wire harness boot meets the door frame was a mess. at the connector in the bulkhead there where chaffed wires and the connector looked stressed. I taped that all up and guess what I now have my original electrical problems (radio will not shut off when door is open, and door lock chime does not work), I think that the may be a cold solder joint ( work done by the dealer) and/or the connector at the door bulkhead has issues. The airbag light is still on, it is another problem! | |
