System Air Flow: Floor/Defrost

When FLOOR/DEFROST is selected:

• The Recirc request button is enabled. If the Recirc request button is selected (indicator ON), the air inlet door actuator positions the air inlet door to close off outside air from entering the passenger compartment. If the Recirc request button is not selected (indicator OFF), the air inlet door actuator positions the air inlet door as to admit only outside air into the passenger compartment. The DATC will automatically revert to the outside air position after approximately 1 to 4 minutes to prevent window fogging.
• The floor door and defrost door actuators position the floor door and defrost door in the OPEN position and the panel door actuator positions the panel door in the CLOSED position, directing airflow to the floor duct, the windshield defroster ducts and the side window demisters. A small amount of airflow from the outboard instrument panel A/C registers will be present.
• The dual coolant control valve is automatically controlled by the DATC module based on the temperature settings.
• The A/C request button is enabled. When the A/C request button is selected (indicator ON), the A/C compressor will operate if the outside air temperature is above approximately 2°C (35°F). When the A/C request button is not selected (indicator OFF), the A/C compressor will not operate and the air cannot be cooled below the outside temperature.
• The blower motor is ON.
