2002 CLK500
Hello!

I have an issue with the electric seat adjustment in my 2002 CLK on the driver's side. All functions operate excepting the seat back recline and head rest.

The seat will recline forward (incline? un-recline? decline?) but not backwards, and the head rest will go up but not down.

I have taken the switch out of the door, cleaned the switches with contact cleaner, re seated all connectors, and manually powered all the motors directly.

My process of reduction leads me to the control box under the seat. When I depress the switch for the above mentioned functions, I can hear the relay click inside, but nothing happens.

Am I in need of a new control box, or can I replace, or reset, or repair a faulty relay inside?

Regards,

Jon.

Same problem here on my 2001 CLK430 drivers seat except everything works except going back and forwards. I too can hear the relay clicking.
Any advice anyone?
