🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box and remove anything inside so nothing falls out.
• Use a flashlight to look at the right side of the glove box for the small “damper” arm (a little slow-down strap).

Step 2: Disconnect the glove box damper arm

• Using a trim removal tool (plastic), gently pop the damper arm off its pin on the glove box.
• The damper is the small arm that makes the glove box open slowly.

Step 3: Release the glove box stops and lower the glove box

• With both hands, push the glove box sides inward to clear the side “stops” (the plastic tabs that keep it from dropping all the way).
• Let the glove box rotate downward slowly.
• Push evenly—don’t twist the box.

Step 4: Remove the cabin filter access door

• Behind the lowered glove box, locate the rectangular cabin filter housing door.
• Press the side tabs and pull the door straight off by hand (use the trim removal tool (plastic) only if needed).

Step 5: Remove the old cabin air filter

• Slide the old filter straight out of the housing.
• Use nitrile gloves if the filter is dusty.
• If leaves/debris are inside the housing, gently pull them out by hand (avoid pushing debris deeper).

Step 6: Install the new cabin air filter

• Look for the airflow arrow on the filter frame.
• Install the filter with the arrow pointing down (toward the floor) on your Outback.
• Slide it in straight so it doesn’t buckle or crush.

Step 7: Reinstall the access door

• Reinstall the housing door and press until the tabs click into place.
• If there are screws on your door version, reinstall them using a Phillips screwdriver #2 (snug only; do not overtighten).

Step 8: Reattach and close the glove box

• Lift the glove box back up and push the sides inward again to get the stops past the dash opening.
• Reconnect the damper arm to its pin (press it on by hand; use the trim removal tool (plastic) only if necessary).
• Close the glove box.

✅ After Repair

• Start the engine and run the fan on medium for 30 seconds to confirm strong airflow and no rattles.
• Switch between fresh air/recirculate and listen for any unusual noises behind the glove box.
• If you notice a musty smell, run the A/C for a few minutes; the new filter may take a short time to “air out.”
