Passenger Compartment Air Filter
The passenger compartment air filter is located
below the air inlet grille, near the passenger’s side
windshield wiper arm. See Engine Compartment
Overview on page 5-12.
The filter traps most of the pollen from the air entering
the air conditioning module. Like the engine’s air
cleaner filter, it may need to be changed periodically.
For information on how often to change the passenger
compartment air filter, see Scheduled Maintenance
on page 6-4.
To change the passenger compartment air filter,
use the following steps:
1. Turn the ignition to ACCESSORY and turn the
windshield wipers on.
2. Turn the ignition to OFF when the windshield
wipers are in the upright position.
3. Raise the hood.
4. Disconnect the windshield washer pump hose
from the fender rail and air inlet grille.
5. Peel back the hood weather-strip from the
passenger’s side of the vehicle halfway to the
center of the hood.
6. Remove the three air inlet grille retainers.
7. Remove the air inlet grille.
8. Remove the old
air filter by pulling
up on its tab.
9. Install a new passenger compartment air filter.
See Normal Maintenance Replacement Parts on
page 6-13 for the type of filter to use. Make sure
it slides under the compartment retainers.
10. Reverse Steps 1 through 7.
