🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box and remove all items by hand.
• Use a flashlight to look at the right side of the glove box for the damper arm (the small strap/arm that slows the glove box).

Step 2: Disconnect the glove box damper arm

• Gently unclip the damper arm from the glove box using your fingers.
• If it’s stubborn, use a trim removal tool (plastic pry tool) to help pop it off gently. Plastic tool helps avoid scratches.
• Damper arm definition: it’s a small linkage that slows the glove box as it opens.

Step 3: Drop the glove box down

• Push the glove box sides inward by hand to release the side stops.
• Let the glove box swing downward to expose the cabin filter access door behind it.

Step 4: Remove the cabin filter access door

• Locate the rectangular cover on the HVAC housing behind the glove box.
• Press the tabs and remove the cover by hand.
• Use a flashlight so you can clearly see the tabs and cover edges.

Step 5: Remove the old cabin air filter

• Pull the old filter straight out by hand.
• Keep it level as you remove it to avoid dumping debris.

Step 6: Install the new cabin air filter

• Check the airflow arrow on the filter frame (it will say AIR FLOW).
• Install the filter in the same direction as the arrow shown for the housing (typically arrow points downward in this style of slot).
• Slide it in evenly so it doesn’t buckle.

Step 7: Reinstall the access door and glove box

• Reinstall the filter cover by hand until the tabs click into place.
• Lift the glove box back up and push the sides inward to pass the stops back into position.
• Reconnect the damper arm by hand (you should feel it snap back on).

✅ After Repair

• 💨 Turn the car ON and run the blower on medium-high for 30 seconds to confirm strong airflow.
• 👃 Check for any rattles, whistling, or a loose cover (signs the access door isn’t fully clipped).
• 🗓️ Plan to replace the cabin filter about every 12 months (sooner in dusty/pollen-heavy areas).
