Blower Motor Speed Control Switch (Manual Control Panel)

Blower motor operation is controlled by 5-position switch mounted on upper left corner of control panel assembly. The A/C on-off switch is incorporated into center of blower switch. When blower switch is off, motor ground circuit is open and blower motor does not operate.

When switch is in first position, current flow from blower motor is restricted by 4 resistor coils in blower motor resistor assembly. With switch in second position, one resistor coil is by-passed and current flow is restricted by 3 resistor coils. In third position, 2 resistor coils are by-passed and current flow from blower motor is restricted by 2 resistor coils. In fourth position, 3 resistor coils are by-passed and current flow is restricted by one resistor coil.
