Air Intake Position Control

HVAC control module determines the position of the air intake control door based on signals from the temperature selector, inside air temperature sensor, outside air temperature sensor and sunload sensor and selects any of the following positions by controlling the position of the air intake control door.

• FRESH position (FRE)
• RECIRCULATION position (REC)
• MIX position (MIX)
  • When the defrost switch is turned on or the "MODE" (air flow) switch is selected to "D/F" mode, HVAC control module fixes the position of the air intake control door to the FRESH position (FRE)
