🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box fully and remove any contents.
• Use a flashlight to look at the right side of the glove box for the “damper” (a small arm that slows the glove box). Damper = the slow-down strap/arm.

Step 2: Disconnect the glove box damper

• On the right side, carefully pop the damper arm off its pin using a plastic trim tool.
• If your damper uses a small screw/clip instead, remove it with a Phillips #2 screwdriver.

Step 3: Release the glove box stops so it drops down

• With both hands, gently push the glove box sides inward to clear the built-in “stops.”
• Let the glove box swing downward slowly.

Step 4: Remove the cabin filter access cover

• Behind the glove box you’ll see the cabin filter housing cover.
• Press the side tabs and pull the cover off by hand (use the flashlight to see the tab locations).

Step 5: Remove the old filter

• Slide the old cabin filter straight out while wearing nitrile gloves.
• Keep it level so debris doesn’t dump into the housing.

Step 6: Install the new filter (correct direction)

• Check the airflow arrow on the new filter frame.
• Install it in the same direction as the old one (the arrow must match airflow direction shown on the housing/filter). Use the flashlight if you can’t read the markings.
• Make sure the filter seats fully and isn’t folded or pinched.

Step 7: Reinstall cover and glove box

• Reinstall the cabin filter housing cover by hand until the tabs click.
• Lift the glove box back up and push the sides inward again to pass the stops.
• Reconnect the damper arm (press it back onto the pin) using a plastic trim tool if needed.
• If a fastener was removed, reinstall it with a Phillips #2 screwdriver (snug only; do not overtighten).

✅ After Repair

• Switch between fresh air and recirculation to confirm normal airflow and no rattles.
