🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and “drop” the glove box

• Open the glove box fully by hand.
• Use a trim removal tool (plastic) (specialty) to gently help the glove box sides flex inward (if needed) so the stops can pass the dash opening.
• Lower the glove box down slowly.

Step 2: Disconnect the glove box damper (soft-open arm)

• On the right side of the glove box, locate the small damper arm (it slows the glove box as it opens).
• Carefully pop the damper arm off its pin using your fingers or the trim removal tool (plastic) (specialty).
• Tip: Support the glove box so it doesn’t drop.

Step 3: Find the cabin filter access door

• Look behind the glove box opening using a small flashlight.
• Locate the rectangular cabin filter cover (typically a small door with tabs).

Step 4: Remove the cabin filter cover

• Release the cover tabs by hand (or gently with the trim removal tool (plastic) (specialty)).
• Pull the cover straight off and set it aside.

Step 5: Remove the old cabin air filter

• Slide the old filter straight out.
• Wear nitrile gloves—filters can be dusty.

Step 6: Install the new cabin air filter (correct direction matters)

• Check the airflow arrow on the new filter frame.
• Install it with the arrow pointing in the same direction as the old filter came out.
• If you didn’t note the old direction: install the new filter so the arrow points toward the blower motor (deeper into the HVAC box).
• Tip: Don’t crush the filter—keep it square.

Step 7: Reinstall the cover and glove box

• Reinstall the filter cover until it clicks into place.
• Reconnect the glove box damper arm by pushing it back onto its pin.
• Lift the glove box back up and guide the stops back into position.
• Close the glove box and reopen it to confirm smooth operation.
