In the diagram, for the actuator, one wire is voltage, the other is ground. Because the lock actuator works both ways, lock and unlock, those wires switch voltage or ground. The wire harness goes into the door on the hinge side, maybe a rubber protective boot covering the wires, See if you can pull boot back far enough to access wires, the wiring color is in the diagram, Activate door lock switch at the master switch or passenger door, doesn't matter. Check those wires for voltage and ground, try it in lock and unlock. Use a voltage tester.
Your local police department may have a slim-jim they can use to unlock door? If something inside the door electrical or mechanical is broken, I'm not sure how to help?
