🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the glove box area

• Put on nitrile gloves and safety glasses.
• Use a flashlight to look behind/around the glove box so you can see the filter cover clearly.

Step 2: Release the glove box damper arm

• Open the glove box.
• On the right side, find the small “damper” arm (it slows the glove box). It’s a small plastic link.
• Use a plastic trim tool set to gently pry the damper arm off its peg (or pull it off by hand if it releases easily).

Step 3: Drop the glove box down

• With the glove box open, press inward on both sides of the glove box to clear the side “stops.”
• Once both sides clear, let the glove box swing downward slowly.

Step 4: Remove the cabin filter housing cover

• Behind the glove box opening, locate the cabin filter access door/cover (a rectangular plastic cover).
• Use a plastic trim tool set (or your fingers) to press the locking tabs and pull the cover straight off.

Step 5: Remove the old cabin air filter

• Slide the filter straight out of the slot.
• Keep the filter level as you pull it out to reduce debris falling into the blower area.

Step 6: Install the new cabin air filter

• Check the airflow marking on the filter (usually an arrow with “AIR FLOW”).
• Install the filter in the same direction as the old one (match the arrow direction). Wrong direction can reduce airflow.
• Slide it in until fully seated—do not bend or crush it.

Step 7: Reinstall the cover and glove box

• Reinstall the filter access cover by pushing it in until the tabs click.
• Lift the glove box back up and press the sides inward again so the stops pass back into place.
• Reconnect the damper arm on the right side (push it back onto the peg until it snaps on).

✅ After Repair

• Start the car and run the fan on medium, then high, to confirm good airflow and no rattles.
• Switch between fresh air and recirculation to ensure normal operation.
• If you hear a ticking sound, recheck that the filter cover is fully latched.
