🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Find the cabin filter access cover

• Go to the passenger footwell and look up under the glovebox using a flashlight.
• You’ll see a rectangular filter cover on the HVAC (heater/AC) box.

Step 2: Remove the filter cover

• If your cover has a screw: remove it with a Torx T20 screwdriver.
• If your cover uses tabs: gently release the tabs using a plastic trim removal tool. A trim tool is a plastic pry tool that helps pop clips without scratching.
• Lower the cover and set it aside.

Step 3: Slide out the old cabin filter

• Pull the filter straight out of the slot by hand while wearing nitrile gloves.
• Keep it level as it comes out to avoid dumping leaves and dust.
• Note the airflow arrow on the filter frame (this matters for the new one).

Step 4: Clean the filter housing

• Use a shop vacuum with crevice tool to remove loose debris from inside the housing opening.
• Tip: Don’t push debris deeper inside.

Step 5: Install the new cabin filter

• Match the new filter’s airflow arrow to the direction you noted from the old filter.
• Slide the new filter into the housing by hand until it seats fully and sits flat.

Step 6: Reinstall the cover

• Reinstall the cover and make sure all tabs are fully engaged by hand.
• If equipped, install the screw using a Torx T20 screwdriver and Torque to 1.5 Nm (13 in-lbs) (snug, not tight).

✅ After Repair

• Start the engine and run the fan on medium, then high, to confirm strong airflow.
• Switch between fresh air and recirculation to confirm there are no rattles from the cover.
• If there’s a musty smell, run A/C for a few minutes on fresh air to help clear old odors.
