Power Door Locks System Components
The power lock system consists of the following components:
• Body control module (BCM)
• Driver door lock cylinder switch
• Front passenger door lock cylinder switch
• Driver door lock switch
• Front passenger door lock switch
• Door lock actuators in each of the doors
• DR LK Fuse 20-amp
Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
• A door lock switch lock or unlock actuation
• A door lock cylinder switch unlock actuation
• A keyless entry transmitter actuation
• An automatic door lock actuation (Personalization function)
• An automatic door unlock actuation (Personalization function)
Door Lock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the lock position, it switches the door lock actuator lock control circuit to voltage. Since the lock actuator unlock control circuits are at ground potential within the BCM, the door lock actuator motors transition to the lock position.
Driver Door Unlock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the unlock position, it switches the driver door lock actuator unlock control circuit to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the left front (LF) door lock actuator motor transitions to the Unlock position.
The driver door lock actuator unlock control circuit is a dedicated control circuit used only for the driver door lock actuator motor. This is done so that the driver door may be unlocked by itself using a keyless entry transmitter or an automatic door unlock function (if programmed).
Passenger Door Unlock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the unlock position, it switches the door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the passenger door lock actuator motors transition to the unlock position.
The door lock actuator unlock control circuits are dedicated control circuits used only for the passenger door lock actuator motors. This is done so that the driver door may be unlocked separate from the passenger doors using a keyless entry transmitter or an automatic door unlock function (if programmed).

Before you replace anything, inspect the connector pins in both the driver's door switch and the passenger door switch. If you don't find any problem with these connector pins, replace the driver's door control switch.

door lock actuator might be faulty or bad electrical contact
take off the door panel and diconnect and reconnect the wiring, you might need to change door lock actuator

Sounds like the blend door actuator. It separates the driver and passenger side from getting air on the AZC system. Here are some instructions on replacing it:
The passenger side blend door actuator is used on all models equipped with Automatic Zone Control (AZC). This actuator is located on the front of the HVAC housing to the right of the floor panel transmission tunnel and cannot be removed from the passenger compartment without instrument panel or HVAC housing removal.

NOTE: This procedure is for AZC Systems (Passenger side only).

1. Disconnect and isolate the battery negative cable.
2. Remove the glove box door. See: Body and Frame\Interior Moulding / Trim
3. Remove the lower I/P glove box door surround panel.
4. Remove the dash assembly. See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
5. Remove the HVAC assembly. See: Housing Assembly HVAC\Service and Repair
6. Unplug the wire harness connector from the blend door actuator.
7. Remove the 2 screws that secure the blend door actuator to the HVAC housing.
8. Remove the blend door actuator from the HVAC housing.

INSTALLATION - AZC (Passenger side only)

1. In stall the blend door actuator on the HVAC housing and tighten the two mounting screws to 2.2 Nm (20 in. lbs.).
2. Plug in the wire harness connector to the blend door actuator.
3. In stall the HVAC unit into the vehicle. See: Housing Assembly HVAC\Service and Repair
4. Install the instrument panel assembly into the vehicle. See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
5. Evacuate the HVAC system.
6. Recharge the HVAC system.
7. Connect and the battery negative cable.

Hope it helps! If you need more, just send me an email at familyguy77351 at yah I wil be glad to finish helping you with more detail.

Remove door panel and check for power at door lock actuator. Most likely faulty actuator if power is at the master and individual power door lock switches.

If your sure you have all the screws out, grab the pocket on the door panel towards the left side, and pull towards you swiftly, the clips should release. Don't tear the vapor barrier. I use a razor blade and cut the adhesive between the vapor barrier and the door, being careful not to cut through the plastic barrier.

I have a 2002 land rover discovery and my passenger front door won't unlock with the interior lock button on the dash or with the key fob. The only way to unlock the door is to pull the handle on the inside of the door. Is the actuator bad?

Please help

pop the door panel loose near the door lock actuator is at top of door;break the cover off of the door lock actuator.manually turn the actuator worm gear out of double lock with a screwdriver and pull the inside handle; not the easiest thing to do...good luck

Got this idea from mpvclub.com: Get some stainless or aluminum sheet metal screws, drill pilot hole into the handle and into the receiving part behind, then screw in the screw. Do on both sides of handle (get appropriate length screw.) When done, get some putty or hardener to fill in the screw slot, let dry, then sand smooth, then paint with body color. Result is great and inexpensive.

more than likely the door lock actuator is bad the multiplex unit sends a signal to the actuator to lock or unlock
