🔧 Fusion - Cabin Air Filter Replacement

Your cabin air filter cleans the air that comes through the vents (heat/AC). When it’s clogged, airflow gets weak and you may notice musty smells or more dust inside.

Difficulty Level: Beginner | Estimated Time: 15-30 minutes

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Clear access at the glove box area

• Open the glove box and remove any items inside.
• Use a flashlight to look along the right side of the glove box for a small damper arm (a little strap/arm that slows the glove box).

Step 2: Lower the glove box

• Gently push inward on both sides of the glove box to release the side stops, then let the glove box swing downward.
• If equipped with a damper arm, carefully pop it off its pin by hand (no tool if possible). Go slow—plastic gets brittle.

Step 3: Remove the lower/side trim panel (if it blocks the filter door)

• If you can’t clearly see a rectangular cabin filter access door behind the glove box, remove the nearby trim panel.
• Use a trim removal tool (plastic) to gently pry the panel clips loose.
• If there are screws, remove them using a 7mm socket with a 1/4" drive ratchet and 6" extension.

Step 4: Remove the cabin filter access door

• Locate the cabin filter cover (rectangular door) behind the glove box area.
• Release the tabs by hand; if tight, use the trim removal tool (plastic) gently.
• Pull the cover straight off and set it aside.

Step 5: Remove the old cabin air filter

• Put on nitrile gloves and safety glasses.
• Slide the old filter out carefully (it may drag on the housing).
• Note the airflow direction arrow on the old filter (usually marked AIR FLOW).

Step 6: Install the new cabin air filter

• Insert the new filter in the same orientation as the old one, matching the AIR FLOW arrow direction.
• Make sure the filter sits flat and fully seats in the housing (no corner folded over).

Step 7: Reinstall the cover and reassemble

• Reinstall the filter access door until the tabs click in place.
• If you removed any trim, reinstall it using the 7mm socket, 1/4" drive ratchet, and 6" extension, then press any clips back in by hand.
• Lift the glove box back up, reattach the damper arm (if equipped), and pop the glove box side stops back into place.

✅ After Repair

• Start your Fusion and run the fan on medium, then high, to confirm stronger airflow and no rattles.
• If you hear a ticking or fluttering noise, the filter may not be fully seated—recheck that it’s flat in the housing.
