The climate control assembly has three system controls:

The A/C heater function selector switch combines a vacuum selector valve with two electrical switches to supply battery positive voltage (B+) to the A/C clutch circuit and the blower motor control circuit.
The temperature selection is accomplished through cable-controlled positioning of the temperature blend door located in the heater core housing.
The blower motor switch controls the blower motor speed by adding or bypassing resistors in the heater blower motor switch resistor.
