🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box and remove any items so nothing falls out.
• Use a flashlight to look at the right side of the glove box for the small “damper” arm (the little arm that slows the glove box from dropping).

Step 2: Disconnect the glove box damper arm

• On the right side, gently pop the damper arm off its pin using a plastic trim removal tool.
• Work slowly—this clip is easy to snap.

Step 3: Drop the glove box down

• Push inward on both sides of the glove box to clear the side “stops” (the molded bumps that prevent it from falling).
• Let the glove box swing down toward the floor.
• If a screw/strap is present on your setup, remove it using a Phillips #2 screwdriver.

Step 4: Remove the cabin filter access cover

• Behind the glove box, locate the rectangular cabin filter cover.
• Release the tabs by hand or with a plastic trim removal tool, then pull the cover straight off.

Step 5: Remove the old cabin air filter

• Pull the filter straight out of the housing using nitrile gloves.
• Use a flashlight to check the housing for leaves and debris; wipe it clean if needed.

Step 6: Install the new cabin air filter (correct direction)

• Look for the airflow arrow on the new filter frame.
• Install it so the arrow points down (toward the floor) for your Forester.
• Slide the filter in evenly—don’t bend or crush it.

Step 7: Reinstall the cover and glove box

• Reinstall the access cover and press until the tabs click in.
• Lift the glove box back up and push the sides inward again so the stops pass the opening.
• Reconnect the damper arm to its pin by pressing it back on by hand (use the plastic trim removal tool only if needed).
• If you removed a fastener, reinstall it with a Phillips #2 screwdriver (snug only; no torque spec needed for this plastic fastener).

✅ After Repair

• Start the engine and run the blower on medium-high to confirm strong airflow.
• Switch between fresh air and recirculation to confirm the fan sound is normal (no rubbing/whistling).
• If you still get a musty smell, consider cleaning the evaporator case (separate service).
