🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box and remove anything inside so it doesn’t spill.
• Use a flashlight to look at the right side of the glove box for the “damper” arm (a small support that slows the glove box).

Step 2: Disconnect the glove box damper arm

• The damper is a small arm on the right side of the glove box. It typically clips onto a pin.
• Use a plastic trim tool set (specialty) to gently pop the damper off its pin if it’s tight. A trim tool is a plastic pry tool that helps release clips without scratching.

Step 3: Drop the glove box down

• With the glove box open, press in on both sides of the glove box near the top to clear the stop tabs.
• Lower the glove box slowly until it swings down toward the floor.

Step 4: Remove the cabin filter access cover

• Behind the glove box you’ll see a rectangular filter housing cover.
• Use your fingers or the plastic trim tool set (specialty) to release the side clips and remove the cover.

Step 5: Remove the old cabin air filter

• Slide the filter (or filter tray) straight out of the housing.
• Keep it level to avoid dumping leaves and dust into the blower area.
• Old filters can be very dusty—wear gloves.

Step 6: Install the new cabin air filter (correct direction)

• Look for an “AIR FLOW” arrow on the side of the new filter.
• Install it the same way the old one came out, with the airflow arrow pointing in the correct direction (usually downward toward the blower on this setup).
• Slide the filter fully in so it sits flat and doesn’t buckle.

Step 7: Reinstall the cover and glove box

• Reinstall the filter housing cover and press until the clips click into place.
• Lift the glove box back up, press in the sides again to pass the stop tabs, and let it close normally.
• Reconnect the glove box damper arm on the right side by pressing it back onto its pin.

✅ After Repair

• Start the engine and run the fan at all speeds to confirm strong airflow and no rattles.
• Switch between fresh air and recirculation to make sure nothing is binding behind the glove box.
• If you notice a musty smell, run A/C on fresh air for a few minutes to help clear moisture.
