Remove the instrument lower passenger panels and glove box.
Pull down front instrument lower cover, and disconnect clips.
Pull it horizontally, and remove from lower cover pawls.
Remove screws, and disconnect harness connector, and remove instrument passenger lower panel.
Remove the filter cover, then remove the in-cabin microfilter.
Take out the in-cabin microfilter from blower unit.
Replace with new one and reinstall on blower unit.
Reinstall the instrument lower passenger panel.
When installing a new microfilter make sure of the following:
- The filter is installed so that the arrow, on the end of the filter, is facing the rear of the vehicle and is pointed upward.
- The microfilter sits on top of the two black plastic tabs, not behind them.
- The ledge on the back side of the microfilter cover panel slides below the microfilter.
If the microfilter is improperly installed, the ledge on the back side of the microfilter cover panel pushes directly into the microfilter, causing
distortion. A distorted microfilter may interfere with the recirculation door.
