Electric Door Locks not working to lock or unlock passenger door

Probably not a whole lot your going to be able to do ,Unless you have a factory or some other professional type scan tool to check for DTC'S - diagnostic trouble code's , an have service repair info for power locks for your car . Computer controlled (BCM) - body control module .
Door Lock System Components
The Power Door Lock System consists of the following components:
• Body control module (BCM)
• Driver door lock switch
• Front passenger door lock switch
• Reversible door lock actuator in each of the doors
• IBCM (PWR) 15-amp fuse
• Driver door cylinder switch, if equipped

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 keyless entry transmitter actuation
• An automatic door lock or unlock actuation
• A last door closed locking (LDCL) actuation
If the driver door cylinder switch feature of the vehicle is functional, the locks may also be operated by a driver door cylinder switch lock or unlock activation


If the driver door cylinder switch feature of the vehicle is functional, the locks may also be operated by a driver door cylinder switch lock or unlock activation
Power Door Lock Switch Operation
Each door lock switch is wired to the body control module (BCM) through a separate door lock/unlock signal circuit. While these circuits are separated between the BCM and respective door lock switch, they are connected into a single circuit within the BCM. The BCM supplies voltage through the door lock/unlock signal circuits to each door lock switch. When either door lock switch is operated, this supply voltage is pulled to ground, providing the BCM with the required lock or unlock signal. In order for the BCM to distinguish between a lock and unlock signal, the lock switch contains two separate paths for this voltage to flow to the same body ground. When the switch is operated to the unlock position, the supply voltage flows to ground through a 1.5 K? resistor. When the switch is operated to the lock position, the supply voltage flows to ground through a different part of the switch circuit, which has no resistor. The BCM then interprets the flow of voltage as a lock or unlock request and powers the door lock actuators to the appropriate lock or unlock position.
Power Door Lock Actuators
The body control module (BCM) powers the reversible door lock actuators by providing battery positive voltage and ground to the appropriate lock and unlock control circuits of the actuators. The Lock control circuits of the driver and passenger door lock actuators are all connected together, however, the Unlock control circuits are connected in a slightly different way. While the unlock control circuits for the passenger door lock actuators are connected together, the driver door lock actuator has a separate unlock control circuit. The system is designed this way so that the keyless entry transmitter may be used to unlock only the driver door. Despite this difference, all of the lock actuators perform much the same way. When the door lock actuators are not active, all actuator Lock and Unlock control circuits are at ground potential within the BCM. Transitioning of the lock actuators to the lock or unlocked position depends upon which control circuits receive voltage and which control circuits receive ground.
• If the BCM is commanding the door lock actuators to Lock, it momentarily switches the lock control circuits to voltage. Since the unlock control circuits are at ground potential within the BCM, the actuators transition to the Lock position.
• If the BCM is commanding all door lock actuators to Unlock, it momentarily switches the unlock control circuits for both the driver and passenger door lock actuators to voltage. Since the lock control circuits are at ground potential within the BCM, all lock actuators transition to the Unlock position.
• If the BCM is commanding only the driver door lock actuator to Unlock, it momentarily switches only the driver door actuator unlock control circuit to voltage. Since the lock control circuit is at ground potential within the BCM, the actuator transitions to the Unlock position.
Power Door Lock and Unlock Operation w/Keyless Entry Transmitter
The keyless entry transmitter may be used to unlock only the driver door. When the unlock button of the keyless entry transmitter is pressed once, the body control module (BCM) receives the unlock request from the remote control door lock receiver (RCDLR). The BCM interprets this single press as an unlock driver door request and responds by switching only the driver door lock actuator unlock control circuit to voltage. With the lock actuator lock control circuit for the driver door at ground potential within the BCM, the driver door lock actuator transitions to Unlock.
If the unlock button of the keyless entry transmitter is pressed a second time within three seconds of the first press, the BCM interprets this second press as a request to unlock the passenger doors and responds by switching the passenger door unlock control circuits to voltage. With the lock actuator lock control circuits at ground potential within the BCM, the passenger door locks transition to Unlock.
To lock all doors with the keyless entry transmitter, a single press of the transmitter lock button is all that is ever needed. The BCM receives the lock doors request from the RCDLR and responds by switching all lock actuator lock control circuits to battery voltage. With the actuator unlock control circuits at ground within the BCM, all actuators transition to Lock.

Check the relays in the fuse box. It appears that the solenoids for locking the doors are working correctly. However it appears that the lock solenoid is not working properly.

Sounds like the main wiring loom into the door has been damaged.
Check near the hinges, where the door swings, to see if any damaged wires. Does the door lock and unlock from the drivers side switch?

The locks don't work from any switch or just the driver's door switch ? The door locks are controlled by the BCM - body control module , that's were the clicking you hear is coming from there are no fuse's that are marked for the locks , fuse's for the BCM .

Door Lock System Components
The power door lock system consists of the following components:
• Driver door lock switch -- Uses a single signal wire for both lock and unlock switch activations
• Front passenger door lock switch -- Uses a single signal wire for both lock and unlock switch activations
• BCM -- Class 2 module which requires programming when replaced
• Reversible door lock actuators in each of the doors
• BCM PWR 15A fuse -- Located in the BCM fuse panel, supplies power for the door lock system

The BCM PWR fuse supplies battery positive voltage to the BCM for the door lock system.
The BCM supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position, the reference voltage is taken directly to ground and the BCM senses 0.0 volts on the signal circuit. If a door lock switch is placed in the unlock position, the reference voltage is taken to ground through a 15k ohm resister that is internal to the door lock switches and senses approximately 2.9 volts on the signal circuit. This is how the BCM determines what portion of the door lock switch was activated.
The BCM, upon receipt of a door lock switch lock or unlock signal, will switch the appropriate door lock actuator control circuits to battery positive voltage. The opposing side of the door lock actuators are connected to ground internally within the BCM through the other door lock actuator control circuit and the doors will lock or unlock appropriately.
Vehicles without keyless entry have two internal drivers in the BCM to control the door lock actuators. All door lock and all door unlock. Vehicles equipped with keyless entry have three internal drivers in the BCM. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.

turn key twice when opening, ie turn right. once drivers door will unlock, turn twice passengers doors will unlock, and locking is turn anti clock wise once will lock all doors, turn twice will set door dead locks.dead locks will stop openand lock internal button working and handle from opening door. the same actions can be applied to the remote one press drivers door, two press passenger doors, press and hold unlock button for 5 seconds and rear window will open.

sequence for freelander lock unlock, to lock 1press = door lock , 2press = door dead lock , to unlock 1 press = driver door unlock, 2 press = passenger doors unlock, also rear window can be operated from fob to do so press and hold unlock button for 3 or more seconds and rear window will roll down.neat feature.hope this helps

Sounds like bad wiring, or bad door lock actuators. Check for power while locking/unlocking the doors.

If remote locks and unlocks driver door but does not unlock passenger doors,then follow the advice above:
Get in the car using the key to unlock the doors. From the passenger side lock and unlock your doors using the button on the passenger door. Get out and the remote should now unlock all the doors with 2 presses.
Worked perfectly for me after several other suggestions (and dealer) failed.

You need to replace the electric door lock solenoid.The electrical part of the solenoid may be compromised and is not letting the solenoid arm retract or extend to lock/unlock your door.
