🔨 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 a flashlight to look along the right side for a small “damper” arm (a little slow-down strap that controls how the glove box drops).

Step 2: Disconnect the glove box damper

• If equipped, gently pry the damper arm off its pin using a trim removal tool (plastic) (specialty).
• Work slowly—this is a small plastic clip.

Step 3: Drop the glove box down

• With the glove box open, press in on both sides of the glove box (the flexible side walls) to clear the built-in “stops.”
• Once the stops clear, lower the glove box down toward the floor.

Step 4: Remove the cabin filter door

• Behind the glove box you’ll see a rectangular filter housing with a cover/door.
• Pinch the tabs on the cover and pull it straight off. If there’s a small screw on your cover, remove it using a Phillips #2 screwdriver.

Step 5: Remove the old cabin air filter

• Pull the filter straight out of the housing.
• Keep it level to avoid dumping leaves and dust.
• Check for acorns/leaves—common in this area.

Step 6: Install the new cabin air filter

• Look for the airflow arrow on the side of the new filter.
• Install it with the arrow pointing down (toward the floor) to match airflow direction in your Civic.
• Slide it in gently; it should seat without bending.

Step 7: Reinstall the cover and glove box

• Reinstall the filter cover by snapping the tabs back in (or reinstall the screw using a Phillips #2 screwdriver).
• Lift the glove box back up and press the sides in again so the stops pass into place.
• Reconnect the damper arm to its pin by pressing it on by hand (use the trim removal tool (plastic) (specialty) only if you need gentle help).

✅ After Repair
