    If it doesnt move than its no good. Try to clean the plunger out with some contact cleaner then lubricate it with some penetrant oil and see if you can get it to move.

    Yep that would be a sign of a malfunctioning actuator.

    What about the volt meter reading 9 volts is that ok or is it not enough and making it just vibrate ?

    if you've pulled it out of its spot, just go ahead and unplug it and hook it up to the battery with jumper wires, that should let you know if its a voltage problem or the actuator is bad

    and if the actuator is good, you might try the switch on the transfer case that turns the actuator on, had my 4x4 go out last summer and it was that little switch and not the actuator, so now i have an extra actuator, as i'm sure i'll need it one day
