Yes, the switches could have just gummed up from lack of use... just like the tracks on the bottom of the recline rear seats (my SDL and 560 both have this issue). Have you pulled the seat to verify the motor is still plugged in? You could simply jump the motor with 12v to see if it moves...

Have you replaced all fuses yet in the box? They're due at this age along with cleaning all contacts within the box.

I get around 0.8-1bar at hot idle in the summer, in gear. 15W50 M1 oil. 1bar is around 14.7psi.

"rough" idle could be from many issues... vac leaks, wrong spark plugs, tired cap/rotor, etc.
