🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Empty and open the glove box

• Remove items from the glove box so nothing falls out.
• Open the glove box fully.
• Use a flashlight to locate the small damper arm (a little shock/strap that slows the glove box).

Step 2: Disconnect the glove box damper

• On the right side, gently pull the damper arm off its pin by hand while using the nitrile gloves for grip.
• Tip: Pull straight outward, not downward.

Step 3: Release the glove box stops

• With the glove box open, press in on the glove box sides (left and right) to clear the built-in stop tabs.
• Let the glove box swing down slowly.

Step 4: Remove the cabin filter cover

• Behind the glove box, find the rectangular cabin filter access door.
• Press the side tabs and pull the cover straight off by hand while using the nitrile gloves.

Step 5: Remove the old cabin air filter

• Slide the old filter straight out.
• Use the flashlight to check how the airflow arrow is oriented (usually points downward toward the blower).
• Tip: Keep the dirty side facing up.

Step 6: Install the new cabin air filter

• Insert the new filter in the same direction as the old one, matching the airflow arrow.
• Push it in evenly so it doesn’t fold or crush.

Step 7: Reinstall cover and glove box

• Reinstall the cabin filter cover by pushing until the tabs click into place.
• Lift the glove box back up and press the sides inward again to get past the stop tabs.
• Reconnect the damper arm to its pin on the right side by pushing it on by hand.
