🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box fully and remove contents by hand.
• Use a flashlight to look at the right side of the glove box for a small “damper” arm (a small slowing strap/arm that controls how fast the glove box drops).

Step 2: Release the glove box damper (if equipped)

• If you see a small arm/strap on the right side, gently pop it off the glove box pin using a trim clip removal tool.
• Go slow—plastic tabs can snap.

Step 3: Drop the glove box down

• Press the glove box sides inward with your hands to clear the built-in stops, then let the glove box rotate downward.
• If your Expedition has any small screws/retainers in the glove box area, remove them using a Phillips #2 screwdriver.

Step 4: Remove the cabin filter access door

• Behind the glove box, locate the rectangular cabin filter cover.
• Release the cover tabs by hand; if tight, gently assist with the trim clip removal tool.
• Remove the cover and set it aside.

Step 5: Remove the old cabin air filter

• Slide the old filter straight out by hand.
• Use a flashlight to note the airflow direction arrow on the filter (this matters for the new one).
• Keep it level to avoid spilling debris.

Step 6: Install the new cabin air filter

• Put on nitrile gloves and install the new filter by hand.
• Match the airflow arrow direction to the way the old one came out (arrow should follow airflow direction through the housing).
• Make sure the filter seats fully and isn’t folded or pinched.

Step 7: Reinstall cover and glove box

• Reinstall the filter access door by hand until the tabs click in.
• Lift the glove box back up and re-engage the side stops by gently pressing the sides inward.
• Reconnect the damper arm (if equipped) by pressing it back onto its pin by hand.
• If you removed screws, reinstall them using a Phillips #2 screwdriver.

✅ After Repair

• Check for normal airflow and listen for any rubbing noises (a sign the filter isn’t seated).
• If there’s a musty smell, run fresh air (not recirculation) for a few minutes.
