DTC 59 | Airflow mode actuator (motor lock) system inspection
--- | ---
POSSIBLE CAUSE | • Airflow mode actuator malfunction • A/C unit (airflow mode link and airflow mode crank) malfunction • Open or short circuit in wiring harness between A/C amplifier and airflow mode actuator

Diagnostic Procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | • Disconnect the airflow mode actuator connector. • Connect battery positive voltage to airflow mode actuator terminal F (or terminal G) and ground to terminal G (or terminal F). • Does the airflow mode actuator operate? | Yes | Connect the connector, then go to Step 3.
No | Go to the next step.
2 | • Remove the airflow mode actuator. • Operate the airflow mode main link manually. • Does the airflow mode main link operate smoothly? | Yes | Replace the airflow mode actuator. (See AIRFLOW MODE ACTUATOR REMOVAL/INSTALLATION.)
No | Replace the airflow mode main link, airflow mode sub link, and the airflow mode crank.
3 | • Disconnect the A/C amplifier connector (24-pin). • Connect battery positive voltage to A/C amplifier connector (24-pin) terminal 1V (or terminal 1U) and ground to terminal 1U (or terminal 1V). • Does the airflow mode actuator operate? | Yes | Inspect the connection at the A/C amplifier connector (24-pin). (See A/C AMPLIFIER INSPECTION [FULL-AUTO AIR CONDITIONER].)
No | Repair the wiring harness.
