Any of these three causes may apply to your situation of your driver's rear door not power locking, specifically the malfunctioning of the 1) relay system, 2) switch motor, or 3) the switch/button itself. Here's a handy diagnostic article that explains this:

This should lead you to the correction of your door's failure to lock.

2002 Cadi Deville, can't get any locks to operate with remote or dash push buttons, the remote operates everthing but the locks! When the remote door lock is pressed, lites flash,horn blows locks not.


Power Door Lock Operation
The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door, but the rear integration module (RIM), which is the master control for the door lock system, determines when the lock functions are permitted. The RIM receives and examines the requested lock function from the individual door modules, or from the remote function actuator (RFA) via the class 2 serial data circuit. The RIM also examines the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. If the RIM determines that a lock or unlock function is permitted, it sends a class 2 message back to the individual door modules commanding them to perform that Lock or Unlock function.
Power Door Lock Components
The power door lock system consists of the following components:
?€¢
Driver door lock switch


?€¢
Passenger front door lock switch


?€¢
LH rear door lock switch


?€¢
RH rear door lock switch


?€¢
LH middle door lock switch (w/ V4U)


?€¢
RH middle door lock switch (w/ V4U)


?€¢
Driver door switch assembly (DDSA)


?€¢
Driver door module (DDM)


?€¢
Passenger front door module (PDM)


?€¢
LH rear door module (LRDM)


?€¢
RH rear door module (RRDM)


?€¢
Left middle door module (LMDM) (w/ V4U)


?€¢
Right middle door module (RMDM) (w/ V4U)


?€¢

?€¢
Passenger front door lock actuator


?€¢

Both rear electric door locks are malfunctioning. Drivers side rear door lock works good when it is cold. the same was true with the passenger rear door lock. now that one will not work at all. the...


to see if it is a switch problem see if the locks work from their respective doors, if the locks work from the switch's on the back doors and not from the drivers switch then the drivers switch is bad. If the locks don't work right from any of the switches then the door lock solenoids are bad. the solenoids are not too hard to change if you are mechanically inclined, switches are not too hard either

2002 Ford Explorer - Drivers side door lock, rear


Aside from the fuses, your drive side power door lock may be failing to work because of a bad door-lock relay system, or, alternatively, the locking switch/button, itself, is not malfunctioning and in need of replacement.

A great handyman site that specifies the above probable causes and more is the following link:

Central Locking


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 door can unlocked with the key manually. The rear doors you have to pull up the latch. If no doors unlock electrically with the remote or drivers door lock, intermittantly or all the time, you will need a Central Locking Electronic Control Module. You will hear the "beep" but no door locks will fire at all. If you have odd door locks not working intermittantly you need a new door lock motor for each door lock that malfunctions. You can hear of the door locks are working electrically. Yes, they are common problem. If you can hear the door lock 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.

2000 Ford Focus electric locks/acuator failure recurring problem


I would follow their recommendation as I had the same problem with my car. They unhooked the power to that door and it was fine. The problem was a short in the wiring in the door that was causing the problem. So maybe get them to check the wiring in the door as well.

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)
