I have to ask one question and when you answer it, you may have it figured out. Does only one actuator go up and down very fast,(machine gun effect) or do all of them? If only on is doing that, then it is most likely the bad actuator. Usually the driver's door latch is the culprit since it is used the most. The actuator is part of the latch, so the latch will need replacing.
