DESCRIPTION

The A/C air filter is designed to reduce particulate and odor entry through the climate control system.

Scheme 59

Scheme 60

1. Remove the glove box(A) from the lift(B).
2. Open the glove box (B). Lower the glove box down completely by removing the glove box stopper (A) to the glove box.
3. Remove the filter cover (A) by pressing the clips inward. Take care not to damage the clips.
4. Replace the air filter (B). The installation direction is marked on the filter.

Scheme 61

Note. In case of driving in an air-polluted area or rugged terrain, check and replace the air filter as frequently as possible.

Replacement period : 15,000 km (9320 mile)

Scheme 62

1. The intake actuator is located at the blower unit.
2. It regulates the intake door by signal from control unit.
3. Pressing the intake selection switch will shift between recirculation and fresh air modes.

Scheme 63

1. Ignition "OFF".
2. Disconnect the intake actuator connector.
3. Verify that the intake 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.
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 64

1. Disconnect the negative (-) battery terminal.
2. Remove the glove box (Refer to «CRASH PAD»(ref-357465-S42759464242010032300000) ).
3. Disconnect the intake actuator connector.
4. Loosen the mounting screw and then remove the intake actuator (A) from the blower unit.
5. Installation is the reverse order of removal.
