The following systems are grouped together into a single integrated control panel:

• in-vehicle entertainment
• clock
• heated back window
• climate control

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 blower motor speed by adding or by passing resistors in the heater blower motor switch resistor.
