🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and unload the glove box

• Open the glove box and remove everything inside.
• Use a flashlight to look along the right side for a small “damper” arm (a little strut that slows the glove box).

Step 2: Disconnect the glove box damper

• On the right side, unhook the damper arm from the glove box using your fingers or a plastic trim removal tool.
• Go slow; the clip pops off gently.

Step 3: Drop the glove box down

• Press inward on both sides of the glove box (near the top) to release the side “stops.”
• Let the glove box rotate downward until you can see the cabin filter access door behind it.

Step 4: Remove the cabin filter cover

• Locate the rectangular cabin filter door.
• Pinch the tabs on the door and pull it straight off by hand (use a plastic trim removal tool only if needed).

Step 5: Remove the old filter

• Slide the old filter straight out.
• Keep it level so debris doesn’t dump into the housing.

Step 6: Install the new filter (correct direction)

• Check the airflow arrow on the new filter’s frame.
• Install it in the same direction as the old one (the arrow must match airflow direction indicated on the filter/housing).
• If it won’t slide, it’s likely flipped.

Step 7: Reinstall the cover and glove box

• Reinstall the cabin filter door until both tabs click in by hand.
• Lift the glove box back up and press the sides inward again to pass the stops back into place.
• Reconnect the damper arm on the right side using your fingers.

✅ After Repair
