📋 Before You Begin

• Park on level ground and set the parking brake.
• Move any items out of the glove box so nothing falls out.
• Have a trash bag ready—the old filter can be dusty.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box fully and remove contents by hand.
• Use nitrile gloves and safety glasses if you’re sensitive to dust.

Step 2: Unhook the glove box damper

• On the right side of the glove box, find the small “damper” arm (a little plastic/metal slow-down strap that keeps the glove box from dropping fast).
• Gently pop the damper off its pin by hand, or use a plastic trim tool set (specialty) to help pry it off carefully.
• Go slow—this clip is easy to crack.

Step 3: Lower the glove box past the stops

• Look for the glove box “stops” (the plastic tabs on the left and right that hit the dash opening).
• Use your hands to press the glove box sides inward so the stops clear the dash opening.
• Let the glove box swing down gently.

Step 4: Remove the cabin filter cover

• Behind the lowered glove box, locate the rectangular cabin filter door/cover.
• Use your fingers to squeeze the cover tabs and pull the cover off. Use a flashlight if visibility is tight.

Step 5: Remove the old cabin air filter

• Slide the old filter straight out by hand.
• Note the airflow direction marking on the filter (usually an arrow). This tells you which way air flows through it.

Step 6: Install the new cabin air filter

• Compare the new filter to the old one to confirm it matches in size.
• Install the new filter with the airflow arrow pointing the same direction as the old one (or matching the airflow marking on the HVAC housing if shown).
• Slide it in straight so the filter frame doesn’t fold.

Step 7: Reinstall the cover and glove box

• Reinstall the filter cover by hand until it clicks into place.
• Lift the glove box back up, press the sides inward again, and let the stops go back into position.
• Reconnect the damper arm by hand (it should snap back onto its pin).

✅ After Repair

• Switch between fresh air and recirculate to ensure the glove box area doesn’t rattle.
• If you notice a musty smell, consider using an A/C evaporator cleaner (optional) at your next service.
