Inspection
1. Ignition "OFF"
2. Disconnect the intake actuator connector.
3. Verify that the actuator operates to the fresh position when connecting 12V to the terminal 3 and grounding terminal 4.
4. Verify that the intake actuator operates to the recirculation position when connecting in the reverse.

Recircualtion
4.55 ± 0.15V
Low voltage : 4.9V or less
Fresh
0.45 ± 0.15V
High voltage : 0.1V or more
6. If the intake actuator is not operated well, substitute with a known-good intake actuator and check for proper operation.
7. If the problem is corrected, replace the intake actuator.
Replacement
1. Disconnect the negative (-) battery terminal.
2. Remove the heater & blower unit.
(Refer to HA group - "Heater Unit")
