Circuit Diagram
InspectionOperating Logic Test (Manual only)Inspect the PTC operation by confirmation logic as follows.1.Entering(1)Set the Floor mode and maximum heating position.(2)Turn off the blower switch.(3)Press the intake (recirculation) button 5 times or more.
Inspection1.Turn the ignition switch OFF.2.Disconnect the temperature control actuator connector.3.Verify that the temperature control actuator operates to the cool position when connecting 12V to terminal 3 and grounding terminal 7.Verify that the temperature control actuator operates to the warm position when connected in reverse.
