Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment particulate air filter. It is located
underneath the hood just below the windshield wiper
arm on the passenger’s side of the vehicle, underneath
the air inlet grille.
The filter traps most of the pollen from air entering the
Climate Control System. Like your engine’s air
cleaner/filter, it may need to be changed periodically to
insure system performance. 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 off the ignition when the windshield wipers are
in the up position.
2. Raise the vehicle hood.
3. Disconnect the windshield washer pump hose from
the fender rail and air inlet grille.
4. Peel back the hood weatherstrip from the
passenger’s side of the vehicle halfway to center.
5. Remove the air inlet grille retainers.
6. Remove the air inlet grille.
7. Remove the air deflector grille in the compartment.
8. Remove the old passenger compartment air
filter.
9. Reverse the steps to install the new air filter.
For the type of filter to use, see Normal Maintenance
Replacement Parts on page 6-13.
