Electric. Seats

Hello, fellow sufferers,

The seat back adjustment no longer twitches with my thick ship. Is this a known mistake? The reason for this is that there are plenty of parts in question, from the memory control unit, via the switch on the seat, the wire harness or the electric motor.

Is there any experience? I don't want to take apart all of them, breaking down various plastic parts, and then finding that it was on the switch.

Greetings from Hamburg

Andreas
