A/C With Heater Mode

With the Fan Speed Switch (X179) in Position I, II or III, the Air Supply Selector Switch (X180) in the combination A/C and Heater Mode, battery voltage is supplied to the Fascia Vent Switch (X181). When the Vent Switch is in position 0 battery voltage is supplied to the A/C Blower Motors (M101) through a resistor in the Blower Resistor Unit (Z112) from the Air Supply Selector Switch. When the Vent Switch is in position 1 battery voltage is supplied to the A/C Blower Motors through a resistor in the Blower Resistor Unit from the Fan Speed Switch (X179).
