• Composed of the following parts:

— Airflow mode actuator

— Airflow mode main link

— Airflow mode door

Airflow Mode Door Operation

• The airflow mode doors move to the OPEN-VENT, OPEN-BI-LEVEL, OPEN-HEAT, VENT HEAT, HEAT/DEF or 

DEFROSTER position, depending on the position of the airflow mode control dial. As a result, the airflow mode 
changes.

A/C UNIT CONSTRUCTION/OPERATION

E5U071161132N01

Construction

• An A/C unit with integrated cooling and heater units has been adopted.

— Evaporator

— Heater core

— Expansion valve

— Air mix damper

— Air intake door

— Evaporator temperature sensor

— Power MOS FET

— Air mix actuator

— Air intake actuator

— Blower motor

Air Mix Damper Operation

• The air mix damper, installed in the A/C unit, controls HOT or COLD positions, depending on the position of the 

temperature control dial. As a result, the airflow temperature is controlled.
