Blower Motor: Description and Operation
With A/C
The Blower Motor's speed is controlled by the Blower Switch in the Heater and A/C Control Assembly. With the switch in the LOW position, all of the
Blower Resistors are in the circuit with the motor so that it runs slowly. In the M1 and M2 positions, the Blower Switch bypasses some of the resistors,
increasing the motors speed.
The Blower Motor is fed through the contacts of the Blower Motor Relay. When the Blower Switch is in the HI position, battery voltage is supplied
through the ORN wire to the coil of the Blower Motor Relay. The relay is energized and its contact supplies battery voltage directly to the Blower Motor
from Fusible Link B.
When the Mode Selector is in the OFF position, no voltage is applied to the Blower Switch and Motor so the blower does not run. In all other positions,
the blower should operate as described.
