Outline

• The ventilation system adjusts the airflow temperature sent from the blower unit or the air vent mode.

Function

• The ventilation system adjusts the airflow temperature based on the position of the air mix door.

• The ventilation system adjusts the airflow mode based on the position of the airflow mode door.

Operation

Air mix door

Full-auto air conditioner

1. The air mix actuator operates according to the airflow temperature control of the climate control unit.

2. The air mix door moves in the COLD or HOT direction according to the operation of the air mix actuator.

3. The airflow volume blowing from the evaporator to the heater core changes by the movement of the air mix door, and the temperature of the air which passes is adjusted.

Dual mode (with dual type climate control unit)

1. When the DUAL mode is ON, the driver and passenger-side air mix actuators operate independently according to the temperature control dial operation or the automatic control of the climate control unit.

2. The driver and passenger-side air mix doors move independently according to the air mix actuator operation.

• For the DUAL mode, refer to the [CLIMATE CONTROL UNIT]. (See CLIMATE CONTROL UNIT [FULL-AUTO AIR CONDITIONER].)

Manual air conditioner

1. The air mix wire operates by operating the temperature control dial of the climate control unit.

2. The air mix door moves in the COLD or HOT direction according to the operation of the air mix wire.

3. The airflow volume blowing from the evaporator to the heater core changes by the movement of the air mix door, and the temperature of the air which passes is adjusted.

Airflow mode door

Full-auto air conditioner

1. The airflow mode actuator operates according to the airflow mode control of the climate control unit.

2. The airflow mode main link operates according to the airflow mode actuator operation.

3. The airflow mode door moves in the VENT, BI-LEVEL, HEAT, DEF/HEAT, or DEFROSTER direction according to the airflow mode main link. The air vent changes by the movement of the airflow mode door.

Manual air conditioner

1. The mode wire operates by operating the mode dial of the climate control unit.

2. The airflow mode main link operates according to the mode wire operation.

3. The airflow mode door moves in the VENT, BI-LEVEL, HEAT, DEF/HEAT, or DEFROSTER direction according to the airflow mode main link. The air vent changes by the movement of the airflow mode door.
