System Airflow Description - EATC/DATC: Panel

When PANEL is selected:

• The recirc request button is enabled. If the recirc request button is selected (indicator on), the air inlet door vacuum control motor will be at full vacuum, closing off outside air from entering the passenger compartment. If the recirc request button is not selected (indicator off), the air inlet door vacuum control motor will be at no vacuum, admitting only outside air into the passenger compartment.
• The panel door and floor/defrost door vacuum control motors are at full vacuum, directing airflow to the instrument panel A/C registers. A small amount of airflow from the side window demisters will be present.
• Blended air temperature is available. Only when A/C compressor operation has been selected by pressing the A/C request button (indicator on), can the airflow temperature be cooled below the outside air temperature.
• 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.
• The auxiliary blower motor is enabled, if equipped.
