My mercedes s500 passenger seat won't go backwards, other directions work. How do I remove the door panel to get at the switch, or the seat cushion to get at the motor?

 

move the seat in all directions to the fullest extent. seat back, headrest, cushion, up, down, then try the seat again. might have lost its normalization. if you need to remove the switch you must remove the wood trim around the seat switches on the door panel then you can remove just the portion with the switches on it. the whole panel does not have to come off.

 

Sound like ur seat control switch is going out doesnt make any sense that motor goes forward and not back its the same motor for both these movements
