GM Service Manual Online
For 1990-2009 cars only

All models come equipped from the factory with a slot in the ventilation system that is ready to accept passenger compartment air filters. These filters are available for purchase from your dealer. You will need to install two filters to provide the proper filtration.

Both outside and recirculated air flows through these filters and removes certain contaminates including pollen and dust particles.

Reductions in airflow which occur more quickly in dusty areas, may indicate that the filters need to be replaced earlier than listed in the maintenance schedule. For how often to replace your air filters, see Maintenance Requirements .

The access panel for the air filters is behind the glove box.

To install the air filters, do the following:


    Object Number: 810404  Size: B3
  1. Lower the glove box door, then push in the sides of the glove box to completely lower the door to allow access to the slot where the air filters will be installed.

  2. Object Number: 810406  Size: B3
  3. Lift the top tab on the cover to remove the filter cover.

  4. Object Number: 880333  Size: B3
  5. Install the lower filter by dropping it down into the slot.
  6. The grooves on the two filters must be lined up with each other as well as with the ventilation housing in order to install the filters properly. The tabs on the filters should face outward towards you and should be at the top of the filters. The arrows on the filters should point to the driver's side of the vehicle.

  7. Then line up the grooves of the second filter with the lower one and slide it in on top of the lower one.
  8. Reverse the steps to remove the air filters and then install new ones.

If you choose not to replace the filter after you remove it, driving your vehicle without one will not cause damage. However, the air will no longer be filtered.
