Heating System

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.
