[R129 SL] FW: schematic request

Maybe you can fixed it. There is nothing special electronics inside. Only
connectors, printed circuit wires and relay's. So I should try to take out
the complete control board. Take a brush with cupper hairs and clean whole
the printed circuit board. Where the cupper wire parts then are disappeared
, you can easily clean the existed  part and well a normal wire over the
missing part from the printed layer. The contact from the relay you can
clean with fine sandpaper. The relay's and connectors are also welded in the
printed circuit. You can well them again with fresh solder tin.  I believe
it is to repair.

Hi all,
        Well I took apart the seat and cleaned every contact I could find
and still nothing would
work.  I then took the control box and turned it upside down to look inside
at the circuit boards and just
as I thought a lot off rust and corrosion on boards. Looking for new control
board setup for my sl seat,
for the drivers side. Anybody just happen to have one ??? Any idea on the
cost of a new one???? I shudder to
think what it might cost at the dealer.
