Hi. Problem is lock works on driver door but unlock doesn't, whether using powerlock or key. Power is getting to actuator. If you use the key to unlock it won't turn completely to right to unlock. Can use inside handle to open door though. Is this actuator or mechanical?
thanks,

You will need to remove the door panel and check it out. try taking the retainer clip off the actuator and see if it operates with no other rods attached to it if not replace it. If you have a test light check for power while activating the switch.

Remove the driver door panel and disconnect the retainer clip so the actuator can be tested with no rods attached. If it does not operate freely, replace the actuator. Also use a test light to confirm power while activating the lock switch.

The owner of a 1998 Mercury Mountaineer reports that the driver door locks but will not unlock with the power lock or key, even though power reaches the actuator. The key will not turn fully to unlock, but the inside handle still opens the door. The expert advises removing the door panel, freeing the actuator from its rods to test it, replacing it if it does not operate, and checking switch power with a test light.
