🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box and remove all contents by hand.
• Use a flashlight to locate the small “damper” arm on the right side (the damper is a small rod that slows the glove box as it opens).

Step 2: Disconnect the glove box damper

• Gently pry the damper off its pin using a plastic trim removal tool (non-marring).
• Tip: Pry straight outward, not upward.

Step 3: Lower the glove box past the stops

• With the glove box open, press inward on both sides of the glove box using your hands to release the side “stops.”
• Let the glove box swing downward slowly.

Step 4: Remove the cabin filter access cover

• Behind the glove box, find the rectangular cabin filter cover.
• Release the cover tabs by hand; if needed, use the plastic trim removal tool (non-marring) gently to help the tabs unclip.

Step 5: Remove the old cabin air filter

• Pull the filter straight out by hand while wearing nitrile gloves.
• Use the flashlight to check for leaves/debris inside the filter housing and remove any loose debris by hand.

Step 6: Install the new cabin air filter

• Match the filter’s airflow direction arrow to the direction shown on the housing/cover (if present).
• Slide the new filter in evenly by hand—don’t bend or crush it.
• Tip: If it won’t slide in, it’s usually upside down.

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, then press the sides inward by hand to pass the stops back into position.
• Reconnect the damper arm by pressing it onto its pin by hand; use the plastic trim removal tool (non-marring) only if necessary to guide it.

✅ After Repair
