Manual Climate Control

SYSTEM AIRFLOW DESCRIPTION - MANUAL CLIMATE CONTROL

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 defrost door and floor console duct door (if equipped) vacuum control motors are at full vacuum and the panel/floor door vacuum control motor is at no vacuum, directing airflow to the instrument panel A/C registers. A small amount of airflow from the side window demisters will be present.
- 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.

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 defrost door vacuum control motors are full vacuum and the panel/floor door vacuum control motor is at no vacuum, directing airflow to the instrument panel A/C registers. A small amount of airflow from the side window demisters will be present.
- 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.

PANEL
When PANEL is selected:
- The air inlet door vacuum control motor is at vacuum, admitting only outside air into the passenger compartment.
- The defrost door vacuum control motors are full vacuum and the panel/floor door vacuum control motor is at no vacuum, directing airflow to the instrument panel A/C registers. A small amount of airflow from the side window demisters will be present.
- The temperature can be adjusted to heat the but the air cannot be cooled below the outside temperature.
- The A/C compressor will not operate.
- The blower motor is on.

OFF
When OFF is selected:
- The air inlet door vacuum control motor is at vacuum, closing off outside air from entering passenger compartment.
- The defrost door vacuum control motors are vacuum, and the panel/floor door vacuum control motor is at full vacuum, closing off airflow to defrost duct, side window demisters, floor duct, instrument panel A/C registers.
- The A/C compressor will not operate.
- The blower motor is off.

PANEL/FLOOR
When PANEL/FLOOR is selected:
- The air inlet door vacuum control motor is at vacuum, admitting only outside air into the
- The defrost door vacuum control motors are at full vacuum and the panel/floor door vacuum control motor is at partial vacuum, directing airflow to the floor duct, the instrument panel A/C registers. A small amount of airflow from the side window demisters will be present.
- The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F).
- The blower motor is on.

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 defrost door vacuum control motors are at no vacuum, directing airflow to the floor duct.
- Blended air temperature is available.
- The A/C compressor will not operate.
- The blower motor is on.

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/floor door vacuum control motor is at partial vacuum and the defrost door vacuum control motors are at no vacuum, directing airflow to the floor duct, the defroster duct and the side window demisters.
- 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.

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/floor door, defrost door vacuum control motors are at no vacuum, directing airflow to the defroster duct and the side window demisters.
- 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.
