2005 chevy colorado battery went dead and when i rechanged it the drivers door window would not go up or down the other 3 did. the electric locks do not work and the horn goes off if i try to open with electronic key

something puts bcm into safe mode. take neg. battery cable off and touch it to pos. post for 30 sec. leave unconnected for 6 hrs then reconnect. should work after that. just did mine. dealer wanted 400$ to change door switch

if power and ground are good replace the switch

check the control on the door some times is loos also the fuse on that door.

Check for door ajar switches not making contact.

Just figured it out and replicated it 3 times..

any type of power/voltage change seems to trigger this issue

The most common symptom is power locks fail and only the driver window quits, however that is on the extended cab.

Steps to fix and it works every time.

take door panel off driver's door
Disconnect the wiring attached to window and power lock control unit
disconnect battery cables
connect the negative to the positive cable(((NO BATTERY CONNECTED)))
This will act to short residual voltage in the system

5 minutes later
place the key in the ignition and turn to the run position
connect the wiring to the window/lock controller
connect the negative cable to the battery
then the positive
open drivers side door
turn key to the off position((do not remove yet)) you should get a series of dings through speakers telling you the key is still in the ignition
once it begins dinging pull the key out and you should hear the door lock solenoids trigger and the windows should work.

Three years and a very unhappy girlfriend who owns the truck. but she's happy now.

hook your battery back up...

I believe you need a new switch in drivers door goto a wrecker , new GM ones are $$$$$, happened to me, i just unhooked battery to clear a CEL and had window open at the time ( won't do that again ) and door locks and drivers window won't work ,, checked fuses ,everything good then took door apart and put power to window motor was able to put it up, googled and found lots of people in same boat , hope it works for you ,,,,D

page 3-39 in owners manual. automatic door locks. do the steps and change too lock 2. this worked on my 2006 colorado crew cab. good luck

i disconecter the battery on my 05 colorado and now my electronic switch to lock/unlock does not work and my driverside window doesnt either.... all fuses are good as well ???

I had the same problem to the T. I look online for all the same solutions and I can only tell you what worked for me. Actually what I think worked, HAHA! I went out to my truck and unplugged both battery terminals from battery and placed them together to supposedly reset the electrical system, "so I was told." After this for about 20 min or so, I went back out and in this order; re-installed positive terminal followed by negative terminal to battery. After this I checked locks and windows and surprise they worked. I've seen a lot of people say that all they did was wait and they worked later, so maybe it was that and not what I did, but who cares, they work now. Give it a shot and if it works for you, GREAT let me know, I HATE CHEVY CAUSE OF THIS......they wanted me to pay for a stupid diagnostic before they would help me........well screw you I fixed myself.
