Toyota Tundra Service Manual > Air Conditioning System(for Automatic Air Conditioning System): Blower Motor Circuit
DESCRIPTION The blower motor is operated by signals from the air conditioning amplifier. Blower motor speed signals are transmitted by changes in the duty ratio. Duty Ratio: The duty ratio is the ratio of the blower motor OFF time (B) to the total of the blower motor ON and OFF time (A + B). The blo ...
