Scheme 61

1. Ignition "OFF"
2. Disconnect the intake actuator connector.
3. Verify that the actuator operates to the recirculation position when connecting 12V to the terminal 3 and grounding terminal 4.
4. Verify that the intake actuator operates to the fresh position when connecting in the reverse.
5. If the intake actuator is not operated well, substitute with a known-good intake actuator and check for proper operation.
6. If the problem is corrected, replace the intake actuator.

Scheme 62

1. Disconnect the negative (-) battery terminal.
2. Disconnect the intake actuator connector.
3. Loosen the mounting screw and then remove the intake actuator (A) from the blower unit. NOTE: Remove the intake actuator through the lower part of the passenger side crash pad.
4. Installation is the reverse order of removal.
