DTC S2.2	Airflow mode actuator (motor lock)
POSSIBLE CAUSE	• Airflow mode actuator malfunction • Heater unit (Airflow mode link and/or airflow mode cranks) malfunction • Climate control unit malfunction • Open or short circuit between airflow mode actuator and climate control unit

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	• Disconnect airflow mode actuator connector. • Connect battery positive voltage to terminal A (or terminal F) and ground to terminal F (or terminal A) of airflow mode actuator connector. • Does airflow mode actuator operate?	Yes	Connect airflow mode actuator connector, then go to Step 3.
1		No	Go to the next step.
2	• Remove airflow mode actuator. • Operate airflow mode main link by hand. • Does airflow mode main link operate smoothly?	Yes	Replace airflow mode actuator. (See AIRFLOW MODE ACTUATOR REMOVAL/INSTALLATION.)
2		No	Replace airflow mode links and/or airflow mode cranks.
3	• Disconnect climate control unit connector. • Connect battery positive voltage to terminal I (or terminal J) and ground to terminal J (or terminal I) of climate control unit connector. • Does airflow mode actuator operate?	Yes	Replace climate control unit. (See CLIMATE CONTROL UNIT REMOVAL/INSTALLATION.)
3		No	Repair wiring harness.
