could be a wiring short, but if you hear the lock motor moving i believe the lock actuator has broken free. the rivets break free at times and i've used screws and washers the reattach the actuator in place without having to pull apart the door. try to see if you hear 1 doorlock at a time. if when you press the button, the motor sounds and theres movement thats your problem. if you press and theres no motor then you either have no power to the motor or its bad. current tester to the switch will tell you either way.

try closing and locking all the doors then unlock the drivers door with the key

has the vehicle been in an accident around the drivers door A pillar? Sounds like there are some wiring issues inside of the harness or connector that goes from the body to the door.

body control module

Could be 1 of 3 different things. #1 the electronic solenoid that controls the lock mecinism has failed. check by feeling/hearing a click in the door when you try to lock/unlock. if you hear the click from that door it means that the linkage is broke or has come apart. If no click it is the solenoid or loose/broken wire. Chances are if it is a broken wire it will be in the plastic tube that runs from the frame into the door.

Biggest reason power door locks and windows stop working: spilt soda, coffee on switch contacts. This is especially true if your window switch is on the middle console. To fix this, with the car turned off (make sure no power going to the window motors) unscrew the switch and run isopropyl alcohol through the contacts. DO NOT USE WATER as the contacts can rust. If you cant unscrew the switch, then gently pour isopropyl alcohol on the switch and allow an hour to dry before trying 2nd reason: your window motor is dead and needs to be replace. 3rd reason: your window maybe off-track, or the track linkages may be stuck or broken. Listen to see if you can hear the vibration of the window motor trying to run to make sure motor not dead, then unscrew the door cover and fix the track or linkage problem.

Sounds like the motor's fried. Its notorious on these cars (I have one).
What ends up happening is the whole mechanism gets gummed up over time and makes the motor work harder just to actuate the "arms" that lock/unlock the door. Over time, eventually the motor burns out, or doesnt provide enough juice to move the arms any more.

The door lock assembly is pretty expensive from the dealer...if you can source a good used one, and lube any moving parts nicely, then it should last.

If you wanna tackle this yourself, here's a writeup showing how.

Good luck!

When you use your remote or insert your key in the Drivers Front door all the door locks should work at the same time by the door lock motors electrically. If you have to manually unlock the door because it will not lock or unlock by the lock motor, you need a door lock motor. The drivers and passengers front doors can unlocked with the key manually only. The rear doors you have to pull up the latch. 
If NONE of doors unlock electrically with the remote or drivers door lock, intermittently or all the time, you will need a Central Locking Electronic Control Module. Pressing the remote button you will hear the "beep", but no door locks will fire at all. 
If you have a few odd door locks not working intermittently or not at all, you will need a new door lock motor for each door lock that malfunctions. You can hear if the door locks are working electrically. Yes, they are common problem. 
If you can hear the door lock motor working but the door still doesn't unlock you need to take the door panel off and lubricate the door latch assembly and work the lock, loosening it up. This is common as well.
Sometimes a bad door lock motor can blow the central locking fuse. You will notice it because it will take a second or two longer to lock and unlock compared to the others. If the door lock motors seem fine, install a the next step up in amperage fuse. (From 15 AMP to a 20 AMP)

try a hard restart, if that doesnt work then you need a new rear window motor. for the hard restart all you have to do is disconnect the battery cables and touch the positive and negative together for about 8 seconds. if that fails then a new motor it is.
