1. Cooler and Heater Blower Operation
*Manual operation
When the blower control SW in the rear A/C control SW is set to any blower speed, a signal is sent to the A/C amplifier.
The A/C amplifier controls the power transistor and operates the rear cooler blower motor and rear heater blower motor at
the set speed.
*Auto operation
When the auto SW in the rear A/C control SW is operated, a signal is sent to the A/C amplifier. The A/C amplifier controls
the power transistor according to the signals from respective sensors, and operates the rear cooler blower motor and rear
heater blower motor.
2. Air Mix Control Servo Motor Control
When the temperature control lever in the rear A/C control SW is operated, a signal is sent to the A/C amplifier. The A/C
amplifier controls the rear air mix control servo motor to operate the damper until it reaches the temperature set by the
temperature control lever.
3. Air Conditioning Operation
The cooler and heater operation can be switched by the mode select SW in the rear A/C control SW.

1-Ground : Always approx. 12 volts
2-Ground : Approx. 12 volts with ignition SW at ON or ST position
