1987 Mercedes 300D Turbo. (or 300E)
Anyone have the schematic of the Automatic Climate Control unit? None of the
pushbuttons do anything. The temp wheel and fan buttons function properly. If I
remove the 14 pin connector from the left side of the unit, I can activate any
of the 7 coils in the switchover valve block by jumpering its pin to +12V and
the corresponding flaps open and close.
