Tips From the Pros
- Interior Ventilation Filter Replacement
haynes logo
The following information is general in nature. It should not be used as your entire source of information when working on your vehicle. Details on your particular vehicle can be found in your Haynes repair manual.

If you have a newer vehicle, it is most likely equipped with an interior ventilation filter. This filter removes dust and pollen from the air you breathe while driving. It is important to change the filter at the interval recommended in your Haynes manual (usually every 15,000 miles) or you will experience reduced airflow through your heating and air conditioning systems.

1 Here's why you need to replace your filter. The old filter on the left is only about a year old

The two most common locations for the interior ventilation filter are behind the glove box or underneath the cowling at the lower edge of the windshield. Often, components such as the cowl cover or glove box must be removed for access to the filter. The exact procedure for your model is listed in your Haynes manual.

Once you've located the filter housing, disengage the clips or fasteners, remove the access cover, then pull the filter out of the housing. Note the orientation of the old filter, since the new filter will need to be installed the same way.

When installing the new filter, be sure to note any markings that indicate how it should be installed. Installation is the reverse of removal.

haynes client testimonials
Ever since I bought my first truck, the first thing I got was a Haynes manual. Since that truck, I've owned 5 other vehicles. Without my Haynes manuals, I wouldn't have got out of some pretty sticky situations. I remember my dad sending me off to pick up my first manual. Ever since then, they have been a huge life saver!! So you can easily say, I'm a dedicated die hard fan from day one!!Thanks!
