When OFF is selected:

• The air inlet door actuator positions the air inlet door to close off outside air from entering the passenger compartment.
• The floor door actuator positions the floor door in the open position, and the panel door actuator, defrost door actuator, and cold air bypass door actuator (if equipped) position the panel door, defrost door, and cold air bypass door (if equipped) in the closed positions. This closes off airflow to the defrost duct, the side window demisters and the instrument panel A/C registers.
• The dual coolant control valve is in the closed position, preventing the flow of hot coolant to the heater core.
• The blower motor is off.
