OPERATION
With the Ignition Switch in "RUN" and the Function Selector Switch in a position other than "OFF", voltage is applied to the Blower Motor. With the Front Blower Switch in "LO", curent flows through the Blower Motor and three resistors. In "MED-LO", current flows through two resistors. In "MED-HI", current flows through one resistor. In "HI", current does not flow through any resistor. With the Function Selector Switch in "OFF", the Blower Motor does not run.
