Manual Climate Control System

MAX A/C
When MAX A/C is selected:
^ The air inlet door vacuum control motor is at full vacuum, closing off outside air and admitting only recirculated air.
^ The panel/defrost door vacuum control motor is at full vacuum and the panel/floor door vacuum control motor is at no vacuum position, directing airflow to the instrument panel A/C registers.
^ The heater control valve (if equipped) is at full vacuum, preventing the flow of hot coolant to the heater core. Blended air temperature is not available.
^ The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F).
^ The blower motor is on.
^ The auxiliary blower motor (if equipped) is enabled. Blended air temperature is not available.

A/C
When A/C is selected:
^ The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment.
^ The panel/defrost door vacuum control motor is at full vacuum and the panel/floor door vacuum control motor is at no vacuum position, directing airflow to the instrument panel A/C registers.
^ Blended air temperature is available.
^ The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F).
^ The blower motor is on.
^ The auxiliary blower motor (if equipped) is enabled. Blended air temperature is available.

PANEL
When PANEL is selected:
^ The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment.
^ The panel/defrost door vacuum control motor is at full vacuum and the panel/floor door vacuum control motor is at no vacuum, directing airflow to the instrument panel A/C registers.
^ The temperature can be adjusted to heat the air but the air cannot be cooled below the outside temperature.
^ The A/C compressor will not operate.
^ The blower motor is on.
^ The auxiliary blower motor (if equipped) is enabled. Blended air temperature is available.

OFF
When OFF is selected:
^ The air inlet door vacuum control motor is at full vacuum, closing off outside air from entering the passenger compartment.
^ The panel/floor door vacuum control motor is at full vacuum and the panel/defrost door vacuum control motor is at no vacuum, closing off airflow to the defrost duct, side window demisters, floor duct and instrument panel A/C registers.
^ The A/C compressor will not operate.
^ The blower motor is off.
^ The auxiliary blower motor (if equipped) is disabled.

PANEL/FLOOR
When PANEL/FLOOR is selected:
^ The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment.
^ The panel/defrost door vacuum control motor is at full vacuum and the panel/floor door vacuum control motor is at partial vacuum, directing airflow to the instrument panel A/C registers and floor duct.
^ Blended air temperature is available.
^ The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F).
^ The blower motor is on.
^ The auxiliary blower motor (if equipped) is enabled. However, the air cannot be cooled unless the A/C is operating on the main climate control system.

FLOOR
When FLOOR is selected:
^ The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment.
^ The panel/floor door vacuum control motor is at full vacuum and the panel/defrost door vacuum control motor is at no vacuum, directing airflow to the floor duct.
^ The temperature can be adjusted to heat the air, but the air cannot be cooled below the outside temperature.
^ The A/C compressor will not operate.
^ The blower motor is on.
^ The auxiliary blower motor (if equipped) is enabled. However, the air cannot be cooled.

FLOOR/DEFROST
When FLOOR/DEFROST is selected:
^ The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment.
^ The panel/defrost door vacuum control motor is at no vacuum and the panel/floor door vacuum control motor is at partial vacuum, directing airflow to the defroster duct, side window demisters and floor duct.
^ The temperature can be adjusted to heat or cool the air below the outside temperature.
^ The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F).
^ The blower motor is on.
^ The auxiliary blower motor (if equipped) is enabled. However, the air cannot be cooled unless the A/C is operating on the main climate control system.

DEFROST
When DEFROST is selected:
^ The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment.
^ The panel/defrost door and panel/floor door vacuum control motors are at no vacuum, directing airflow to the defroster duct and side window demisters.
^ Blended air temperature is available.
^ The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F).
^ The blower motor is on.
^ The auxiliary blower motor (if equipped) is enabled. However, the air cannot be cooled unless the A/C is operating on the main climate control system.
