  1. Turn the ignition off.

  2. Disconnect the intake actuator connector.

  3. Check that the intake actuator operates in the fresh air position when 12 V is applied to terminal 3 and ground is applied to terminal 7.

    Check that the intake door actuator moves to the recirculation position when the connections are reversed.
