[Mk2] [Generic] Heat control servo motor

[ashley]

I'm trying to find the wiring diagram for the servo motor that controls the temperature of the air that gets blown into the cabin, which also opens and closes the valve in the water supply to the heater matrix (in the frunk). This one:





I've got the wiring diagram section of the technical manuals out, the "Radiator Fan and Air Conditioning" section seems the obvious place to look, and I can find the diagrams for the "fresh / recirc" servo motor, and for the "air vent mode" servo motor (ie which vents in the dash the air flow gets directed to).

But I can't see anything for the variable resistor for the air temperature control, or the wiring for this servo motor.

Can anyone point me towards the right section please???
