For 1990-2009 cars only

Your vehicle has a passenger compartment air filter. It is located on the passenger side at the base of the windshield and can be accessed through a removable panel under the hood of the vehicle.

The filter traps most of the pollen from air entering the module. Like your engine's air cleaner/filter, it may need to be changed periodically.

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

  1. Raise the hood.

  2. Object Number: 1202596  Size: B3
  3. Unscrew and remove the three clips and the access panel.

  4. Object Number: 1202598  Size: B3
  5. Remove the old passenger compartment air filter.
  6. Then reverse the steps to install the new air filter and replace the access panel.
