Blower Motor Circuit
BLOWER MOTOR CIRCUITCIRCUIT DESCRIPTION
The blower motor is operated by signals from the A/C amplifier. Blower motor speed signals are determined by changes in the duty ratio*.
The blower motor control controls the blower motor speed.The blower motor control reads the signal from the A/C amplifier and controls rotation and speed.
HINT: *: The duty ratio is the ratio of the blower motor ON time (B) to the total of the blower motor ON and OFF time (A+B).
