The doors cant be lock with eaither switch
All doors? Check the fuse...see owner's manual for info. Also verify that it is the vehicle's lock switches...or the keyless entry fob. If it is a single door, this can be a tricky difficult ordeal to find the "source" of the problem.
The difficulty is due to the fact that the negative/positive wires reverse polarity at door lock relays each time the lock is electrically exercised. The locks are activated by an electromagnet solenoid, which reverse when the supply current reverses polarity. For example, you may be able to lock a door with the switch then not be able to unlock it...or vice versa. If one of the wires has a fault, and the door locked [or unlocked], the relay was also "tripped/switched" with the "good" wire. When that happened, the relay effectively reversed the wire polarities...meaning that the faulty wire cannot energize the relay/solenoid to activate the lock-unlocking mechanism to reverse the process..
Simply, put...this is not likely a do-it-yourself fix, unless you have fair DC electrical skills, and a shop manual with complete wiring diagrams. The problem could be a poor wire connection, a broken wire, a faulty relay, a faulty solenoid, or a combination of these...or even a physical fault in the mechanical linkage for the lock.
If your vehicle has a locking lifting hatch back...and this is the "door" that won't operate, this can be very aggravating as there is no manual override, without removing the door/hatch trim and manually moving the linkage.
Hopefully it is the fuse.....good luck.
SOURCE: drivers side door lock
my power lock on drivers side door wont unlock the key wont unlock it either how can i get the door unlocked
SOURCE: power locks not working right
Hey, this might work.....get in truck, close doors, put key in ignition in lock position.....hold down the door lock button on driver side door control and wait for the lock control to be displayed on the information screen(odometer read-out).....it should say like lock 1, lock 2, lock 3, lock 4.....or something, I always reset mine to LOCK 1, to do this hold the odometer reset button on dash for a sec or two til it changes settings, then release, repeat till you get to LOCK 1, then quickly press and release odometer reset button to exit program, this is the function to lock doors over 15 mph and when out of park and to unlock doors when returned to park......yours' might be set to another function number....try it out, let me know if this helps.........good luck!
SOURCE: driver door auto--locks, windows, etc. not working. all other doors working
cable probably became disconnected in door..
SOURCE: 08 avalanche pass side power door lock not working
if you have any knowledge of automotivce electrical, (and that you need to use a "circuit tester" and not a test light) test for power when someone presses the button. it wouldnt be uncommon for most vehicles for the lock actuator/solenoid/duty actuator to wear out, get weak and fail. this is most probable. given that this is an 08, have you checked withe dealer to see if its still under warranty. if we are only talking a few miles and they wont do anything, look in your owners handbook and get the 1 800 number and get GM's customer service involved. cheers.
SOURCE: door locks and power window
Just did this procedure I got from coloradofans.com forums:
"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." - Coloradofans.com forums

Class 2 and Power Door Serial Data Links
The class 2 and power door data circuits are both serial data links. The serial data circuits replace cables in the vehicle by multiplexing (time-sharing) data to and from each device over a single wire referenced to ground. If the power door serial data is lost, both the rear door module (RDM) and the passenger door module (PDM) enters the sleep mode. With the RDM and the PDM in sleep mode, no power door operations are possible.
Your best bet is to take it to the dealer or an ASE certified repair shop .
