Without Heater

Rear Interior Roof Mounted Systems
These systems operate with the front system - they do not operate independently. However, control of the rear blower motor speed is possible when the front system if off. Rear air circulation without the refrigerant function is possible by operating the rear blower control switch.

These self-contained units operate on inside (recirculated) air. Air enters the unit and passes through the evaporator core into the passenger compartment through the air distributor duct. The front system controls the rear system. A three-speed blower switch controls the rear interior roof-mounted system.
