Power Head Rest Switch
 

I have a 1991 300E, the driver side power head rest decided to take a break from work. I think the problem is the switch since it feels slightly different than the passenger side switch now. How do you remove the switch panel on the door without making a mess of it?

I would also like to remove and clean or replace the window switch but have not been able to locate the procedure for this.

Thanks

Try some spray on electrical contact cleaner first.

Power Seat Switch R+R (See Picto-grams Below):

Window Lift Switches (Console):
Pry up the front of the carpet in the tray under the Driver's Armrest ...remove the single Phillips screw...[Now look at the plastic surround inset into the wooden piece at the shifter...GENTLY using a small plastic spatula...pry it up
and off] ...lift the wooden console cover upwards from the back...Pivoting
forward 90 degrees (there are two plastic hooks that slide under the ashtray
piece [On the front of the Console Cover]and you are pivoting the console cover so as not to break them.)
individual window switches may now be GENTLY pulled up and out.

Thanks, that will be tomorrow mornings project.

However, I will put odds on the weak link: the plastic pinion inside the seatback. To get access to that you need to take the seatback off. Procedure is buried somewhere in the forum. You can get a replacement part for 30-40 bucks, but judicious wrapping with duct tape solved my problem.
