🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box fully and remove contents by hand.
• Use a flashlight to look along the right side for the glove box “damper” (a small strap/arm that slows the glove box). Damper = the little arm that controls the drop speed.

Step 2: Detach the glove box damper

• Carefully pop the damper end off its pin using a trim removal tool (plastic).
• Set the damper aside so it isn’t pulling on the glove box.

Step 3: Lower the glove box past the stops

• Gently push in on both sides of the glove box (near the side walls) with your hands to clear the built-in stops.
• Let the glove box swing downward toward the floor.

Step 4: Remove the cabin filter access door

• Behind the glove box, locate the rectangular cabin filter cover.
• Release the cover tabs by hand (use a trim removal tool (plastic) only if needed).
• Remove the cover and set it aside.

Step 5: Remove the old cabin air filter

• Put on nitrile gloves.
• Slide the old filter straight out.
• Keep it level to avoid dumping leaves and dust into the housing.

Step 6: Install the new cabin air filter

• Check the airflow arrow on the new filter frame.
• Install it in the same direction as the old one (airflow arrow should match the vehicle’s airflow direction printed on the housing/cover, if present).
• Slide the filter fully into the slot without crushing the pleats.

Step 7: Reinstall the cover and glove box

• Reinstall the filter cover and snap the tabs in place by hand.
• Lift the glove box back up and push in on the sides to get past the stops again.
• Reconnect the damper to its pin by hand (use the trim removal tool (plastic) only if necessary).

✅ After Repair
