Blower Motor: Description and Operation
Blower Motor Speed Control
The A/CCM controls the speed of two blower motors which deliver airflow to the air conditioning unit. The blower motors are regulated by power transistor modules which provide a linear variation of blower speed.
Relationship Manual Control Blower Speed / Voltage
NOTE:
Blower motors are inhibited when the engine coolant temperature is below 35 °C and heating is demanded, unless DEFROST is selected.
