RELAY.... actuators are not designed for a push function and a pull function. They only know "move"... multiple relays are used to get the whole push/pull function. When one relay is on, the other is off, each time a relay switches to on, the actuator moves... do a google search for relay wiring for door locks and you'll find a diagram of what i'm talking about.

the actuator could be bad... but I doubt it.
