Passenger Compartment Air Filter

The passenger compartment air filter is located in
the engine compartment below the air inlet grille,
near the passenger's side windshield wiper arm.
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.
