The driver's seat in my 1989 Mercedes 300 SE is changing positions on its' own. What can I do to stop it?

Assuming you have power seats, if you don't intend to change the seating position once you set it, you can simply reach under the seat from the back and unplug the motors, or remove the fuse associated with the power seats.
