What you need to do is remove all of your possessions in the glove box area and you will either need your fingers or a "+" head, short screw driver to remove the absorber arm on the right side of the glove box.
once the absorber is removed from the glove box let it drop down to the carpet and you'll see the blower motor housing and a bunch of wires. the tray for the filter should either be white or black. you will see tabs on either side of the tray's face, squeeze them together and slide the tray out.
Once you see the filter, remember the way it rests in the tray for this is the best way to filter the air going through the cabin.
Also note on the side of the new filter will show you an "UP" arrow. make sure the arrow is facing up in the tray!
