DescriptionThe Power Relay Assembly (PRA) consists of the positive and negative main relays, pre-charge relay, pre-charge resistor and battery current sensor.
Circuit Diagram
DescriptionThe evaporator temperature sensor will detect the evaporator core temperature and interrupt compressor relay power in order to prevent evaporator from freezing by excessive cooling. The evaporator temperature sensor has the Negative Temperature Coefficient (NTC).
Inspection1.Turn the ignition switch OFF.2.Disconnect the intake actuator connector.3.Verify that the intake actuator operates to the fresh position when connecting 12V to terminal 3 and grounding terminal 4.Verify that the intake actuator operates to the recirculation position when connected in reverse.
