AIRFLOW MODE ACTUATOR INSPECTION [FULL-AUTO AIR CONDITIONER]

id0740a1801700

Caution

•  If the lever position exceeds the operation range shown in the figure, the circuit in the actuator could be damaged. Always perform an actuator operation inspection with the lever movement within the range shown in the figure.

L.H.D.

1.  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2.  Remove the airflow mode actuator. (See AIRFLOW MODE ACTUATOR REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)

3.  Apply battery positive voltage and connect the ground to the airflow mode actuator terminals as indicated in the table below and verify the operation condition.

B+ Terminal	Ground Terminal	Operation
A	B	VENT → DEFROSTER
B	A	DEFROSTER → VENT
