The passenger compartment air filter is located underneath your hood below the windshield wiper arm, on the passenger's side (below the air inlet grille) of the vehicle.

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 Part A: Scheduled Maintenance Services .

  2. Raise the hood.
  3. Disconnect the windshield washer pump hose from the fender rail and air inlet grille.
