• the floor door actuator positions the floor door in the closed position, and the panel/defrost door actuator positions the panel/defrost door to direct airflow to the defrost duct and side window demisters.
• temperature control can be adjusted by directing the airflow through and around the heater core.
• the A/C request button is disabled.
• the A/C compressor will operate automatically if the outside temperature is above 2°C (35°F).
