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 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 Scheduled Maintenance .

To change the passenger compartment air filter, use the following steps:

  1. Put the ignition in 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. Remove the hood weather-strip from the passenger's side of the vehicle (peel back halfway to center).
  6. Remove the three air inlet grille retainers.
