BLOWER MOTOR ASSEMBLY

Its purpose is to draw in passenger compartment air and send it through the evaporator core and the heater core, if desire. It consists of a 12V electronic motor and a squirrel cage style fan blade.

Motor : magnet motor

1. Rated voltage : 12V

2. Without load

- speed : 3300 rpm (min)

- current : 3.0A (max)

3. Temperature range in use: -30°C ~ 80 °C

POWER TR

Blower speed is controlled by the fan control switch and power TR. Changing the fan switch from positions 1 through 7, allowing the fan to run faster.

HIGH SPEED BLOWER RELAY

When the blower switch is positioned at 8^th speed, the FATC controller will apply a ground to the control side of the high-speed blower relay. This allows battery voltage, to pass through its contacts to the coil in the high-speed blower relay. When it happens, the blower motor operates at high-speed.

ACTUACTORS

INTAKE DOOR ACTUATOR

The intake door actuator (fresh/recirculation actuator) is a 12V electric motor, located side the blower motor assembly, and operated by the intake control switch.

It allows an occupant to choose between fresh (outside) air or recirculated inside air by moving the intake (fresh/recirculation) door to the desired position. When the door has reached the desired position, the actuator stops.

TEMP DOOR ACTUATOR

TEMP DOOR ACTUATOR is located side of the heater unit. The actuator controls the position of the temperature blend door based on the voltage signal from the FATC module. Potentiometer inside actuator sends a feedback signal to the controller and controller cuts off the voltage signal coming from the controller when the required door position is achieved.
