Recirculate Mode

With the Fan Speed Switch (X179) in position I, II or III, the Fascia Vent Switch (X181) in position 1, and the Air Supply Selector Switch (X180) in the recirculate air position, the Vent Switch supplies battery voltage to the two A/C Blower Motors (M101) through a resistor in the Blower Resistor Unit (Z112). The A/C Blower Motors run recirculating air within the vehicle. At the same time, the Air Supply Selector Switch (X180) supplies battery voltage to the Heater Air Recirculation Solenoid (K123). The Recirculation Solenoid is energized, closing the fresh air inlet allowing the Heater Blower Motor to also recirculate air within the vehicle cabin. If the Vent Switch is moved to position 0, battery voltage is removed from the A/C Blower Motors.
