When panel is selected:

  • The air inlet blend door, with no vacuum being applied, blocks recirculated air and allows outside air. Air flows through the system to the driver, passenger and center registers.
  • The vent/register blend door is at partial vacuum to direct airflow to the driver, passenger and center registers.
  • The defrost blend is at full vacuum and defrost airflow door is at no vacuum, closing off airflow to the windshield defroster hose nozzles and footwell ducts.
  • The temperature setting can be changed manually to heat the air but air cannot be cooled below the outside temperature.
  • The A/C compressor is disabled when VENT is selected.
  • The blower motor is on.
