Airflow Mode Actuator Inspection (Auto A/C)

Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)
Remove the following parts:
1. Passenger-side front scuff plate (See FRONT SCUFF PLATE REMOVAL/INSTALLATION .)
2. Passenger-side front side trim (See FRONT SIDE TRIM REMOVAL/INSTALLATION .)
3. Glove compartment (See GLOVE COMPARTMENT REMOVAL/INSTALLATION .)
4. Dashboard under cover (See DASHBOARD UNDER COVER REMOVAL/INSTALLATION .)
5. Lower decoration panel (See DECORATION PANEL REMOVAL/INSTALLATION .)
6. Passenger-side lower panel (See LOWER PANEL REMOVAL/INSTALLATION .)
7. Passenger-side front heat duct (See FRONT HEAT DUCT REMOVAL/INSTALLATION .)
Remove the airflow mode actuator. (See AIRFLOW MODE ACTUATOR REMOVAL (AUTO A/C) .)

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.
