Driver Seat Malfunctioning on 1990 Mercedes-Benz 300SE

The driver's seat moves forward and the back of the seat reclines when the vehicle is started. It occurs about half of the time I start the vehicle. What could be the cause of this malfunctioning?

The seat switches go out a lot, but first do an electrical inspection of the seat switch before you just replace it.
