Blower Motor: Description and Operation
Manual
Circuit Description
Blower control
With the ignition switch in ON and the blower switch in any position except OFF, the blower relay coil energizes and the blower relay contact closes.
Battery voltage is then applied to the blower motor through the closed contacts of the blower relay and then ground is provided to the blower motor
through the blower resistor and the blower switch. As the blower switch is moved from OFF to HI, resistance of the resistors (built in to the blower
resistor) will decrease and battery voltage applied to the blower motor will increase. This will increase the blower motor speed. When the blower switch
is in HI, all of the resistors are bypassed and the maximum voltage is now applied to the blower motor so that it runs at the highest speed.
