Ive searched this a few times and read to normalize the seat. Problem is that I cant move the bottom part of the seat at all. Everything else works, the whole seat moves, headrest, etc. Anyone have any idea. I called mb and they said it was probably the seat switch which is 449 buks.

 

well could be a fuse. or a bad switch, there are fuses for backrest and seat bottom. so could be that. sometimes though you need to move the seat bottom cushion, the front and rear parts of the cushion can move up down.move the backrest all the way front and also do the headrest , move all the posible positions to the full range of travel. then try to move the seat again.

some of the fuses can be found in the little compartments behind the passenger seat. the floor pops up.
