šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Open the glove box
- Open the glove box fully and use a flashlight so you can see the sides clearly.
Step 2: Release the glove box stops
- With your hands (use nitrile gloves if you want), press the glove box sides inward so the built-in āstopsā can slip past the dash opening.
- If it feels stuck, use a plastic trim removal tool (specialty) to gently help the side clearādonāt pry hard.
- Go slowāplastic tabs break easily.
Step 3: Lower the glove box door
- Let the glove box swing down toward the floor.
- If your Outback has a small ādamperā arm on the right side, unclip it gently by hand so the glove box can drop farther (the damper is a small support arm that makes the glove box open slowly).
Step 4: Remove the cabin filter access cover
- Behind the glove box, locate the rectangular cabin filter cover.
- Release the cover tabs by hand; if needed, use a plastic trim removal tool (specialty) to help pop the tabs free.
Step 5: Remove the old cabin air filter
- Slide the filter straight out.
- Use a shop towel to wipe out loose leaves/dust from the filter slot.
Step 6: Install the new cabin air filter
- Check the airflow direction marking on the filter (usually an arrow that says āAIR FLOWā).
- Install the filter in the same direction as the old one came out. (If you didnāt check the old one, point the airflow arrow downward toward the blower housing for this setup.)
- Slide it in evenlyādonāt bend or crush the filter.
Step 7: Reinstall the cover and glove box
- Snap the filter cover back on by hand until the tabs click.
- Reattach the glove box damper arm (if equipped) by hand.
- Lift the glove box back up and press the sides inward again so the stops pass the dash opening, then close it.
ā After Repair
- š Start the vehicle and run the blower on medium speed. Confirm airflow feels stronger and there are no rattles.
- š If you hear a tapping noise, the filter may not be fully seatedāreopen and reseat it.
- š§¾ Consider writing the date/mileage on the filter edge with a marker for next time.
