1999 E320 Seat Headrest Restraint Motor Non-op
 

I've tracked down why my drivers seat headrest isn't working.. The motor is out, I tested it with 12v and no sign of life whatsoever..

But my question is, how am I supposed to take that out to replace it? Would this be a job for the Mercedes-Benz dealership??

Did you apply the 12v directly to the motor?
If not you should open up the seat and have a look.
Usualy the wiring breaks inside the seat.
