🔨 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 nitrile gloves and safety glasses if the filter is dusty.

Step 2: Release the glove box stops

• On each side of the glove box, gently push the glove box walls inward with your hands to clear the side “stops.”
• Lower the glove box further once the stops pass the dash opening.
• Go slow—plastic tabs break easily.

Step 3: Detach the glove box damper arm

• On the right side, locate the small damper arm (it’s a little strut that makes the glove box open slowly).
• Carefully pop it off its pin by hand. If it’s tight, use a small flathead screwdriver to gently pry it off.

Step 4: Remove the cabin filter cover

• Behind the glove box, find the rectangular cabin filter housing cover.
• Pinch the tabs and pull the cover straight off by hand. Use a flashlight for visibility.

Step 5: Pull out the old cabin filter

• Slide the filter tray/filter straight out.
• Note the airflow arrow on the filter and how it’s oriented (usually AIR FLOW down on this Civic).
• Place the old filter in a bag to keep dust out of the interior.

Step 6: Install the new cabin filter

• Install the new filter in the same direction as the old one, matching the airflow arrow.
• Make sure it seats fully and doesn’t buckle or fold.

Step 7: Reinstall the cover and glove box

• Reinstall the housing cover by pushing it on until the tabs click.
• Reconnect the damper arm by pressing it back onto its pin by hand.
• Lift the glove box back up and push the sides inward again to pass the stops back into place.

✅ After Repair

• Start the car and run the fan at different speeds to confirm strong airflow.
• Listen for any rattles behind the glove box (a sign the cover isn’t fully clipped).
• If there’s a musty smell, run A/C for 5 minutes.
