Hi,
When you try to use the power lock, does the actuator make a sound? As far as pulling the cable, there is a sheath over the actual cable. I attached a pic below. Let me know if that is what you are referring to.
Also, if the actuator isn't making any noise, check and confirm there is power to pins 1 and 2 at the connector. If there is, replace the actuator. If there is no power, let me know. If you look a pic 2, I highlighted the two pins that should have power when the switch is pressed. One will have power for locking and the other is unlocking.
If the lock assembly needs replaced, that means the door latch assembly has failed. Let me know if you need directions for that.
Let me know.
