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 panel door and floor/defrost door vacuum control motors are at full 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 request button is illuminated and will be disabled.
- The A/C compressor will operate if the outside temperature is above approximately 2°C (35°F).
- The blower motor is on.
- The auxiliary blower motor is enabled, if equipped.

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 door and floor/defrost door vacuum control motors are at full 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 request button is enabled. The A/C compressor will operate and the indicator will illuminate if the A/C request button is selected and the outside temperature is above approximately 2°C (35°F).
- The blower motor is on.
- The auxiliary blower motor is enabled, if equipped.

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 floor/defrost door vacuum control motor is at full vacuum and the panel door vacuum control motor is at partial vacuum, directing airflow to the floor duct and 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 request button is enabled. The A/C compressor will operate and the indicator will illuminate if the A/C request button is selected and the outside temperature is above approximately 2°C (35°F).
- The blower motor is on.
- The auxiliary blower motor is enabled, if equipped.

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 door and floor/defrost door vacuum control motors are at no vacuum.
- The A/C request button is disabled.
- The blower motor is off.
- The auxiliary blower motor is disabled, if equipped.

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 floor/defrost door vacuum control motor is at partial vacuum and the panel door vacuum control motor is at no vacuum, directing airflow to the floor duct. A small amount of airflow from the instrument panel A/C registers, defroster duct and side window demisters will be present.
- Blended air temperature is available.
- The A/C request button is enabled. The A/C compressor will operate and the indicator will illuminate if the A/C request button is selected and the outside temperature is above approximately 2°C (35°F).
- The blower motor is on.
- The auxiliary blower motor is enabled, if equipped.

FLOOR/DEFROST
When the FLOOR/DEFROST is selected:
- The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment.
- The floor/defrost door vacuum control motor is at partial vacuum and the panel door vacuum control motor is at no vacuum, directing airflow to the floor duct, the defroster duct and the side window demisters. A small amount of airflow from the instrument panel A/C registers will be present.
- Blended air temperature is available.
- The A/C request button will not illuminate and is disabled. To reduce fogging, the A/C compressor will operate automatically if the outside temperature is above approximately 2°C (35°F).
- The blower motor is on.
- The auxiliary blower motor is enabled, if equipped.

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 door and floor/defrost door vacuum control motors are at no vacuum, directing airflow to the defroster duct and side window demisters. A small amount of airflow from the instrument panel A/C registers and floor duct will be present.
- Blended air temperature is available.
- The A/C request button will not illuminate and is disabled. To reduce fogging, the A/C compressor will operate automatically if the outside temperature is above approximately 2°C (35°F).
- The blower motor is on.
- The auxiliary blower motor is enabled, if equipped.
