My drivers seat head rest does not work. Since the switch is on a console inside the drivers door. The seat moves to all other positions with the two other switches.
In my '91 the headrest got "stuck" from not moving for a long time... I just pushed the switch up and kinda pushed the headrest up at the same time... worked after that.
