I have a couple of minor problems with the driver-side seat on my 1986 560SL.

Specifically, the seat reclines whilst driving, albeit very slowly, so that every 20 minutes I have to crank the seat back up to its original position. Also, the height adjustment feature is not working, in that I can’t raise or lower the seat’s height (in fact I can’t actually move the seat height control lever at all).

Anyone have any suggestions?

Much appreciated, Ryan
