HEATING / AIR CONDITIONING  AIR CONDITIONING SYSTEM(for Manual Cooler System)  Rear Blower Motor Circuit  


DESCRIPTION

The blower motor assembly reads the signal and controls operation and speed changes of the blower motor.

If the blower air volume is weak, or there are any other blower malfunctions such as the temperature or air volume cannot be changed, the following causes are possible.

Malfunction Status Factor
·

Blower does not operate at all. (No air comes out.)

·

Blower airflow volume cannot be changed.

·

Blower airflow volume is continuously weak.

·

Blower airflow volume is sometimes weak.
