Gently push the glovebox retaining arm out of the way to unclip it.
Then, slowly and carefully lower the glovebox door towards the floor. Or, in my case, the glovebox door will just fall off immediately.
The cabin air filter on the Subaru XV Crosstrek is located behind the glove compartment in the either the upper left or directly center, depending on model year. See the attached image for reference.
If you live under a thousand oak trees, as I do, your filter will be extra gross.
Bask in how truly awful the old filter is and pat yourself on the back for choosing to replace it.
Carefully push the glovebox retaining arm back into place and close the glovebox.
When you close the glovebox, the two side stoppers will automatically re-seat themselves.
Finally, put all your stuff back into your glove compartment. While you’re at it, maybe toss the trillion papers you’ve accumulated or relocate them into your home.
Turn on your AC and smell the fresh air. You’ll be able to notice a difference immediately!
Next: Disable that awful beep
While you’re still in the car, disable the Crosstrek unlock sound in about 30 seconds of work (your ears will thank you). :)
Changing the PCV valve on your Subaru XV Crosstrek (or Impreza) is part of your recommended 30,000 mile maintenance.
