Answer
It sounds like you have an open in the actuator.
You can check this with an ohmmeter.
Should you need assistance checking the actuator for resistance, write me back with the amount of wires going to the actuator and the colors of the wires.
If it is only 2 wires, remove the actuator test for resistance.
If the actuator has a reading of INF or 0.00, the actuator is faulty.
