🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box fully by hand.
• Remove any items inside so they don’t spill.
• Use a flashlight to look along the right side of the glove box for the small “damper” arm.

Step 2: Disconnect the glove box damper

• Use a trim removal tool (plastic) (specialty) to gently pop the damper arm off its small peg on the glove box.
• The damper is a small support piece that slows the glove box when it opens.
• Go slow—this clip is easy to snap.

Step 3: Drop the glove box down

• With both hands, push the glove box sides inward (near the top) to clear the side stops.
• Once the stops clear, let the glove box swing down toward the floor.
• Use nitrile gloves and safety glasses to protect your hands and eyes from dust.

Step 4: Remove the cabin filter cover

• Behind the glove box, locate the rectangular cabin filter housing cover.
• Press the tabs on the cover and pull it straight off by hand.
• Use a flashlight if the tabs are hard to see.

Step 5: Remove the old cabin air filter

• Slide the old filter straight out by hand.
• Keep it level so leaves and dust don’t dump into the housing.
• If it’s full of leaves, vacuum the housing.

Step 6: Install the new cabin air filter

• Check the airflow arrow on the new filter.
• Install it in the same direction as the old one (typically AIR FLOW points downward).
• Slide the filter in until it sits flat and fully seated.

Step 7: Reinstall the cover and glove box

• Reinstall the housing cover by hand until the tabs click into place.
• Lift the glove box back up and push the sides inward again to get the stops back past the dash opening.
• Reconnect the damper arm by pressing it back onto its peg by hand (use the trim removal tool (plastic) (specialty) only if needed).
