DTC 59	Front airflow mode actuator (motor lock) (past)
POSSIBLE CAUSE	• Front airflow mode actuator malfunction • Front A/C unit (airflow mode links and/or airflow mode cranks) malfunction • Open or short circuit between front airflow mode actuator and front climate control unit

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	• Disconnect front airflow mode actuator connector. • Connect battery positive voltage to terminal F (or terminal G) and ground to terminal G (or terminal F) of front airflow mode actuator connector. • Does front airflow mode actuator operate?	Yes	Connect front airflow mode actuator connector, then go to Step 3.
1		No	Go to the next step.
2	• Remove front airflow mode actuator. (See FRONT AIRFLOW MODE ACTUATOR REMOVAL/INSTALLATION.) • Operate airflow mode main link by hand. • Does airflow mode main link operate smoothly?	Yes	Replace front airflow mode actuator. (See FRONT AIRFLOW MODE ACTUATOR REMOVAL/INSTALLATION.)
2		No	Replace airflow mode links and/or airflow mode cranks.
3	• Disconnect front climate control unit connect (24-pin). • Connect battery positive voltage to terminal 1F (or terminal 1H) and ground to terminal 1H (or terminal 1F) of front climate control unit connector (24-pin). • Does front airflow mode actuator operate?	Yes	Inspect the connection of the front climate control unit connector.
3		No	Repair wiring harness.
