🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and release the glove box

• Open the glove box fully and support it with one hand.
• On the right side, disconnect the glove box “damper” arm (the small slow-down strap). Use a trim removal tool (plastic) to gently pry it off its pin. A damper is a small arm that prevents the glove box from dropping fast.

Step 2: Drop the glove box down

• Press inward on both sides of the glove box to clear the built-in stop tabs.
• Let the glove box swing downward toward the floor.

Step 3: Remove the cabin filter access cover

• Behind the glove box, locate the rectangular cabin filter housing.
• Release the cover tabs by hand (or gently with the trim removal tool (plastic)) and pull the cover straight off.
• If your cover uses screws on your trim, remove them with a Phillips #2 screwdriver.

Step 4: Pull out the old filter

• Slide the filter tray/filter straight out toward you.
• Keep it level to avoid dumping leaves and dust.
• Tip: Pull slowly to prevent a debris shower.

Step 5: Install the new cabin filter

• Check the airflow arrow on the side of the new filter.
• Install it in the same direction as the old one (typically AIR FLOW arrow pointing down on this Civic).
• Slide the filter fully back into the housing until it seats evenly.

Step 6: Reassemble the glove box

• Reinstall the cabin filter cover by pushing it on until the tabs click (or reinstall screws with a Phillips #2 screwdriver).
• Lift the glove box back up and press the sides inward again to pass the stop tabs back into place.
• Reconnect the damper arm on the right side by pushing it back onto its pin by hand.

✅ After Repair

• Start the engine and run the blower fan on all speeds to confirm good airflow.
• Turn A/C on and sniff for musty odors; a new filter often helps right away.
• If airflow is still weak, the filter may be installed backwards or not fully seated.
