šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Open and empty the glove box
- Open the glove box and remove everything inside.
- Use a flashlight to look at the right side of the glove box for a small ādamperā arm (a little strut that slows the glove box).
Step 2: Disconnect the glove box damper arm
- On the right side, gently pop the damper arm off its pin using a plastic trim tool set (specialty).
- Tip: Pry gently from the outside edge.
Step 3: Drop the glove box down
- Squeeze the glove box side walls inward with your hands to clear the two stop tabs.
- Let the glove box swing down toward the floor slowly.
Step 4: Remove the cabin filter door
- Behind the glove box, find the rectangular filter access door.
- Press the side tabs and pull the door straight off. Use a plastic trim tool set (specialty) only if needed.
Step 5: Slide out the old filter tray and filter
- Pull the filter tray straight out with your hands.
- Remove the old filter from the tray while keeping it level (so debris doesnāt spill).
Step 6: Install the new cabin air filter
- Put the new cabin air filter into the tray.
- Look for the airflow arrow on the filter. Install it with the arrow pointing down (toward the floor) on your Civic.
- Slide the tray back in until fully seated.
Step 7: Reinstall the filter door and glove box
- Reinstall the access door by aligning it and pressing until the tabs click in.
- Lift the glove box back up and squeeze the sides in again to get the stops past the dash opening.
- Reconnect the damper arm on the right side by pressing it back onto its pin.
ā After Repair
- Start the engine and run the blower fan on high for 30 seconds.
- Check for normal airflow and make sure there are no rattles behind the glove box.
- If you still have a musty smell, consider running the A/C for a few minutes and checking for moisture in the cabin.
