🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box and remove manuals and items so nothing falls out.
• Use a flashlight to look at the right side of the glove box for the small damper (a little “slow-down” arm).

Step 2: Disconnect the glove box damper

• On the right side, gently pop the damper arm off its pin using a trim removal tool (plastic).
• If it’s tight, work it off slowly—don’t pry against the soft dash plastic.

Step 3: Release the glove box stops and lower the glove box

• Push inward on both sides of the glove box to clear the built-in stops.
• Let the glove box swing downward to expose the cabin filter housing behind it.
• Push one side at a time if needed.

Step 4: Remove the cabin filter housing cover

• Find the rectangular cabin filter cover directly behind the glove box.
• Press the locking tabs and pull the cover straight off by hand.
• If a tab is stubborn, use a trim removal tool (plastic) to help press the tab (gently).

Step 5: Remove the old cabin air filter

• Slide the old filter straight out.
• Keep it level as you pull it out so leaves and dirt don’t dump into the housing.
• Use a flashlight to check for leaves inside; remove loose debris by hand with nitrile gloves.

Step 6: Install the new cabin air filter

• Look for the airflow direction arrow on the filter frame.
• Install it in the same direction as the arrow marking for airflow (commonly points downward in this style of housing).
• Slide the filter in fully so it sits flat and doesn’t buckle.

Step 7: Reinstall the housing cover and glove box

• Reinstall the filter cover by aligning it and pushing until the tabs click.
• Lift the glove box back up and push the sides inward again to pass the stops back into place.
• Reconnect the damper arm on the right side by snapping it back onto its pin.
