I really doubt one loose door latch will keep all the door locks from working . There are a lot of thing's involved in the power door locks ,relay's , wiring , master control switch etc..... Viewing wiring diagrams , testing electrical circuit's , PWR LOCKS 20A fuse etc....Are the power door locks and the driver power window inoperative?

SOURCE: power door locks and drivers window have failed on 2004 colorado
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. LATER
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

I've had the exact opposite issue with my 2005 Equinox.
My rear door is locked and will not unlock.
SOURCE: power door locks on a 2004 chevy tahoe don't work
The door locks on my 1999 tahoe stopped working and I checked the fuse, which was fine. The problem turned out to be that the fuse for my cigarette lighter was bad and for some reason it also must be working in order for the door locks to work. Put in a new cigarette lighter fuse and the door locks worked again!
