🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and Empty the Glove Box

• Use your hands to open the glove box fully.
• Remove all items from the glove box.
• Use a flashlight to look along the right side of the glove box for the small damper arm. The damper arm is a small plastic support that slows the glove box as it opens.

Step 2: Disconnect the Glove Box Damper Arm

• Use your fingers to gently slide the damper arm off the small peg on the right side of the glove box.
• Do not pull hard; the arm should pop off with light pressure.
• Support the glove box with one hand.

Step 3: Lower the Glove Box

• Use both hands to squeeze the left and right sides of the glove box inward.
• This lets the glove box stops clear the dashboard opening. The stops are small molded bumps that keep the glove box from dropping too far.
• Slowly lower the glove box down toward the floor.
• No bolts are removed, and no torque spec applies to this step.

Step 4: Remove the Cabin Filter Cover

• Use the flashlight to locate the rectangular cabin filter cover behind the glove box.
• Use your fingers to press the side tabs on the filter cover.
• Pull the cover straight out and set it aside.
• Press the tabs, do not pry them.

Step 5: Remove the Old Cabin Air Filter

• Use your fingers to slide the old cabin air filter straight out.
• Keep the filter level so leaves and dust do not spill into the blower housing.
• Look for the airflow arrow on the old filter before removing it completely.

Step 6: Install the New Cabin Air Filter

• Use your hands to slide the new cabin air filter into the slot.
• Install it with the airflow arrow pointing downward, matching the HVAC airflow direction in your Outback.
• Make sure the filter sits flat and does not fold or bunch up.
• A folded filter can cause poor airflow.

Step 7: Reinstall the Filter Cover

• Use your hands to line up the cabin filter cover with the opening.
• Push the cover in until both side tabs click into place.
• Gently tug the cover with your fingers to confirm it is locked.

Step 8: Reinstall the Glove Box

• Use both hands to raise the glove box back into position.
• Squeeze the sides inward again so the glove box stops pass back into the dashboard opening.
• Reconnect the damper arm onto the peg on the right side using your fingers.
• Open and close the glove box once to make sure it moves smoothly.

• ✅ Check that air comes strongly from the vents.
• ✅ Listen for abnormal fan noise, which may mean the filter is not seated flat or debris fell into the blower area.
• ✅ Replace the cabin air filter about every 12,000-15,000 miles, or sooner in dusty conditions.
