The following information about various modes that can be selected lets you know when your A/C compressor is running and also explains how the air is flowing.

Max A/C The air inlet door vacuum control motor is at full vacuum, closing off outside air and admitting only recirculated air. The floor/defrost door and panel/floor door vacuum control motors are at full vacuum, directing airflow to the instrument panel A/C registers. Blended air temperature is available. The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F). The blower motor is on. A/C The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment. The floor/defrost door and panel/floor door vacuum control motors are at full vacuum, directing airflow to the instrument panel A/C registers. Blended air temperature is available. The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F). The blower motor is on. Panel The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment. The floor/defrost door and panel/floor door vacuum control motors are at full vacuum, directing airflow to the instrument panel A/C registers. The temperature can be adjusted to heat the air, but the air cannot be cooled below the outside temperature. The A/C compressor will not operate. The blower motor is on. Off The air inlet door vacuum control motor is at full vacuum, closing off outside air from entering the passenger compartment. The floor/defrost door vacuum control motor is at full vacuum and the panel/floor door vacuum control motor is at no vacuum, closing off airflow to the defrost duct, side window demisters, the floor duct and the instrument panel A/C registers. The A/C compressor will not operate. The blower motor is off.

Panel / Floor 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/floor door vacuum control motor is at partial vacuum, directing airflow to the floor duct and the instrument panel A/C registers. The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F). The blower motor is on. Floor 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/floor door vacuum control motor is at no vacuum, directing airflow to the floor duct. The temperature can be adjusted to heat the air, but the air cannot be cooled below the outside temperature. The A/C compressor will not operate. The blower motor is on. Floor / Defrost 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/floor door vacuum control motor is at no vacuum, directing airflow to the floor duct, the defroster duct and the side window demisters. The temperature can be adjusted to heat or cool the air below the outside temperature. The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F). The blower motor is on. Defrost The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment. The panel/floor door and floor/defrost door vacuum control motors are at no vacuum, directing airflow to the defroster duct and the side window demisters. The temperature can be adjusted to heat or cool the air below the outside temperature. The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F). The blower motor is on.
