AIR CONDITIONNING

HI

I am puzzled when I look at the Ac knobs on the back of the center panel of my Avanti II 1981.  The fan switch has 3 positions for only 2 broaches in the back and there is a wire coming from the thermostat knob to the fan knob. how does all this work?

Any help?

thank you in advance.

Here is how the A/C is wired on my '78 model.  The fan control has an On/Off function but with variable resistor, rather than a 3-position switch like yours. Functionally, the power is supplied by the yellow wire.  When the fan switch is turned on, full 12V power is sent via the black jumper to the thermostatic switch.  So, the fan must be turned on to enable the thermostat. In turn, the thermostatic switch controls the power to the compressor clutch and throttle kicker.  The other black wire from the fan switch is the variable voltage power to the fan motor.  If you are not already familiar with it, Bob Johnstone's Studebaker site has a wealth of technical information, including Avanti II.  The tech pages can be accessed at

I hope that this is helpful.
