Rick,

While you test is a good attempt, it's not a good simulation.  The 
Screwdriver doesn't present any resistance to
the latch.  But when the door is closed, there is pressure placed on 
the latch, from the seals (if nothing else)
other wise the door would rattle.  It's possible that the wire 
between the roof and the door which handles the
current for the solenoid, has enough strands broken that it can't 
handle enough current to fire the solenoid with
the resistance.

This sounds like the wire that controls the signal to the air 
distribution board is not getting to the solenoid.
Possible causes are a bad switch, wire has come off the switch, 
broken wire between the switch and the
solenoid.

Since you say the door will not go up or down, then the only thing 
common to both is the power supplied to
the switches.

We have done many articles in The Brickline on the subject, including 
wiring diags.
