AIRFLOW MODE ACTUATOR INSPECTION

BHE074061070W02

1. Connect battery positive voltage to airflow mode actuator terminal F (or G), and ground to terminal G (or F), and then verify that the airflow mode actuator operates as shown in the table.

  • If the operation condition is not normal, replace the airflow mode actuator.

Terminal | Airflow mode actuator operation
--- | ---
F | G
B+ | Ground | DEFROSTER→VENT
Ground | B+ | VENT→DEFROSTER

2. Verify that the resistance between terminals A and E, and C and E matches the airflow mode actuator operation as shown in the graph.

  • If the operation condition and resistance are not normal, replace the airflow mode actuator.
