A/C Mode

With the Fan Speed Switch (X179) in position I, II or III, the Air Supply Selector Switch (X180) in the air conditioning mode, battery voltage is supplied to the Heater Or A/C Relay (K125). The Relay is energized, diverting battery voltage from the Heater Blower Motor (M111) via the normally closed relay contacts to the A/C Blower Motors (M101). The Heater Blower Motor stops running. The A/C Blower Motors take the place of the Heater Blower Motor and run at the speed selected by the Speed Switch as described above.
