🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box fully and remove all contents by hand.
• Use a flashlight to look along the right side for the glove box damper (the small “slow-open” arm).

Step 2: Release the glove box damper

• On the right side of the glove box, gently pop the damper off its pin using a nylon trim removal tool set (a plastic pry tool that helps prevent scratches).
• If it’s tight, carefully assist with a small flathead screwdriver while protecting the plastic with the trim tool.

Step 3: Drop the glove box down

• Press the glove box sides inward with your hands to clear the built-in stops.
• Let the glove box swing downward slowly.
• Tip: Push one side at a time.

Step 4: Remove the cabin filter access cover

• Behind the glove box, locate the rectangular cabin filter cover.
• Press the cover’s side tabs and remove the cover by hand.
• Use a flashlight so you can clearly see the tabs and avoid breaking them.

Step 5: Remove the old cabin air filter

• Slide the filter straight out by hand.
• Wear nitrile gloves—the old filter can be dusty.
• Note the airflow direction arrow on the filter frame (you must match this on the new filter).

Step 6: Install the new cabin air filter

• Insert the new filter into the housing by hand.
• Match the old filter’s orientation, using the airflow direction arrow as your guide.
• Make sure it seats flat and doesn’t buckle.

Step 7: Reinstall the cover and glove box

• Reinstall the cabin filter cover by hand until the tabs click into place.
• Lift the glove box back up and press the sides inward to pass the stops again.
• Reconnect the damper to its pin on the right side using your hands (assist gently with the nylon trim removal tool set if needed).
