🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glovebox

• Open the glovebox and remove all items.
• Use nitrile gloves and safety glasses if the filter area is dusty.

Step 2: Disconnect the glovebox damper arm

• On the right side of the glovebox, find the small “damper arm” (a small support piece that lets the glovebox open slowly).
• Use a trim removal tool (plastic) to gently pop the damper arm off its pin.
• Go slow—plastic clips break easily.

Step 3: Drop the glovebox down

• Press the glovebox sides inward (near the top edges) to clear the stops.
• Let the glovebox swing down toward the floor.
• Use a flashlight to look behind the glovebox for the filter access door.

Step 4: Remove the cabin filter cover

• Locate the rectangular cabin filter cover directly behind the glovebox.
• Squeeze the tabs on the left and right of the cover, then pull the cover straight off by hand.
• If it’s tight, use the trim removal tool (plastic) to gently help release one tab.

Step 5: Remove the old cabin air filter

• Pull the filter straight out.
• Keep it level so debris doesn’t spill into the blower housing.
• Use a flashlight to check for leaves or debris inside the slot; remove by hand with nitrile gloves.

Step 6: Install the new cabin air filter

• Match the airflow direction arrow on the new filter to the airflow direction shown on the old filter or on the HVAC case.
• Slide the new filter in straight without crushing the pleats.

Step 7: Reinstall the cover and glovebox

• Reinstall the cabin filter cover until both side tabs click in place.
• Lift the glovebox back up and press the sides inward again to get past the stops.
• Reconnect the damper arm to its pin by hand; use the trim removal tool (plastic) only if needed.
