Climate Control System (System Airflow Description)

SYSTEM AIRFLOW DESCRIPTION

Max A/C
When MAX A/C is selected:
- the air inlet door actuator closes off outside air and admits only recirculated air.
- the recirc button is disabled and the indicator is illuminated.
- the defrost door actuator is in the full closed position, directing airflow to the floor/panel door.
- the floor/panel door actuator is in the full panel position, directing airflow to the instrument panel A/C registers. A small amount of airflow from the floor duct 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.

PANEL
When PANEL is selected:
- the recirc request button is enabled. If the recirc request button is selected (indicator ON), the air inlet door actuator closes off outside air from entering the passenger compartment. If the recirc request button is not selected (indicator OFF), the air inlet door actuator admits only outside air into the passenger compartment.
- the defrost door actuator is in the full closed position, directing airflow to the floor/panel door.
- the floor/panel door actuator is in the full panel position, directing airflow to the instrument panel A/C registers. A small amount of airflow from the floor duct 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.

PANEL/FLOOR
When PANEL/FLOOR is selected:
- the recirc request button is enabled. If the recirc request button is selected (indicator ON), the air inlet door actuator closes off outside air from entering the passenger compartment. If the recirc request button is not selected (indicator OFF), the air inlet door actuator admits only outside air into the passenger compartment.
- the defrost door actuator is in the full closed position, directing airflow to the floor/panel door.
- the floor/panel door actuator is positioned partially between the floor and panel position, directing airflow to the floor duct and the instrument panel A/C registers.
- 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.

OFF
When OFF is selected:
- the recirc request button is disabled.
- the air inlet door actuator closes off outside air.
- the defrost door actuator is in the full closed position and floor/panel door actuator is in the partially open position.
- the A/C request button is disabled.
- the blower motor is OFF.

FLOOR
When FLOOR is selected:
- the recirc request button is enabled. If the recirc request button is selected (indicator ON), the air inlet door actuator closes off outside air from entering the passenger compartment. If the recirc request button is not selected (indicator OFF), the air inlet door actuator admits only outside air into the passenger compartment.
- the floor/panel door is in the floor position and the defrost door fully closes, directing airflow to the floor duct. A small amount of airflow from the defrost duct and side 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.

FLOOR/DEFROST
When the FLOOR/DEFROST is selected:
- the recirc request button is enabled. If the recirc request button is selected (indicator ON), the air inlet door actuator closes off outside air from entering the passenger compartment. If the recirc request button is not selected (indicator OFF), the air inlet door actuator admits only outside air into the passenger compartment.
- the floor/panel door actuator is in the full floor position and the defrost door is partially open, directing airflow to the floor duct, the defroster duct and the side window demisters.
- 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.

DEFROST
When DEFROST is selected:
- the air inlet door actuator opens, admitting only outside air into the passenger compartment.
- the floor/panel door actuator is in the full floor position.
- the defrost door is in the fully open position, directing airflow to the defroster duct and side window demisters. A small amount of airflow from the floor duct will be present.
- blended air temperature is available.
- the A/C request button will illuminate and is enabled. To reduce fogging, the A/C compressor will operate automatically, regardless of indicator status, if the outside temperature is above approximately 2°C (35°F).
- the blower motor is ON.
