Passenger Compartment Air Filter (If Equipped) - Buick 2001 Century Owner's Manual

Passenger Compartment Air Filter
The filter traps most of the pollen from the air entering
the air conditioning module. Like your 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 "Maintenance Schedule" in
the Index.
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 hood.
The passenger compartment
air filter is located
underneath your hood just
below the windshield wiper
arm, on the passenger's side
(underneath the air inlet
grille) of the vehicle.
3. Disconnect the windshield washer pump hose from
the fender rail and air inlet grille.
4. Remove the hood weatherstrip from the passenger's
side of the vehicle (peel back halfway to center).
5. Remove the air inlet grille retainers.
6. Remove the air inlet grille.
7. Remove the passenger compartment air filter.
8. Then replace the old air filter with the new one. For
the type of filter to use, see "Normal Maintenance
Replacement Parts" in the Index.
9. Reposition the air inlet grille.
10. Reinstall the air inlet grille retainers.
11. Reattach the hood weatherstrip.
