Question about 2002 Chevrolet TrailBlazer
Power window, power locks all went out
If all that happened at once, highly suspect a broken wire harness that feeds your door panel.
I think there are separate circuits for the locks and the windows and mirror.
At the factory, I believe the doors are installed on the vehicle with the wire harnesses already in them, means they plug the door harness into a receiving socket in an under-dash harness.
I'd wonder if the vehicle had been in an accident on that side.

Check the fuses first. If that dont work take the door apart the wiers have problably lost the connection due to kids and chocolate.

Your chevy uses two fuses for the system. The power lock actuators are on the 15 amp fuse inside the truck. The fuse for the switches (locks and mirrors) are under the hood. For 99 to 04 (I think those are the years) there is a TSB on replacing the 3 amp fuse under the hood with a 5 amp fuse because this is a well known problem of having these blow.
Your drivers side window is a different issue. If the rest are working your problem is in the motor or getting power to the motor. The wires that go from the body to the door often crack and break with the opening and closing of the door.

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
