Drivers side window and remote locking system is not working in my 2005 Chevrolet Colorado. I just replaced a dead battery and the problem seemed to occur at the same time the battery went dead. I was able to crank the almost dead battery and it was at that time when the window and door locking system stopped working.
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.
Had same problem after disconnecting battery and tried everything I read and nothing worked. Found the post hear about plugging door a few min ago and went to try it before I took to dealer.. well decided to check again and everything started working on its own.. what is that all about.
