CONSTRUCTION
The air conditioning unit consists of the No. 1 cooler evaporator sub-assembly, heater radiator unit sub-assembly*1, damper servo motors*2, No. 1 cooler thermistor (evaporator temperature sensor) and blower motor with fan sub-assembly.
The No. 1 cooler evaporator sub-assembly and heater radiator unit sub-assembly*1 are mounted transversely to achieve a compact and lightweight form.
A bus connector is used in the wire harness connection, which connects the servo motor to the air conditioning amplifier assembly.*2
Sliding doors are used for the air mix control doors, thus making the air conditioning radiator assembly more compact.

Depending on the model, a cool air duct with a shutter is provided to the upper glove box side area of the front passenger side side register duct. The upper glove box can be used as a cool box by opening the shutter while the cooler is operating.
