I have started work on my fourth Grand AM. This is a '95 four door. The door
switch will lock the door but not un-lock. I can hear the motor (solenoid?)
move when trying to un-lock but the rod does not move. It does not seem to
be binding because it moves by hand normally. The factory manual is little
help. The two front doors are bad the two rear work right. The mechanism is
buried deep in the door and I can not even see it.
