🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Empty and open the glove box

• Open the glove box and remove anything inside so it doesn’t fall out.
• Use flashlight to look along the right side of the glove box for the small “damper” arm (a little strut that slows the glove box).

Step 2: Release the glove box stops

• Push in on both sides of the glove box (with your hands) to clear the rubber/plastic stops so the glove box can swing down farther.
• Go slow—firm pressure, not force.

Step 3: Disconnect the glove box damper (if equipped)

• If a damper arm is present on the right side, gently pop it off its peg using the trim removal tool (plastic).
• A trim tool is a plastic pry tool that helps release clips without scratching.

Step 4: Locate the cabin filter access door

• With the glove box lowered, look behind it for a rectangular access cover (cabin filter door).
• Use flashlight to clearly see the tabs/screws holding it.

Step 5: Remove the cabin filter door

• If your cover uses screws, remove them with a 7mm socket, 1/4" drive ratchet, and 6" extension for 1/4" ratchet.
• If your cover uses squeeze-tabs, press the tabs by hand (use the trim removal tool (plastic) only if needed) and pull the door off.

Step 6: Remove the old cabin air filter

• Pull the filter straight out of the housing with your hands while wearing nitrile gloves.
• Keep it level to avoid dumping leaves and dust into the housing.

Step 7: Install the new cabin air filter (correct direction)

• Check the airflow arrow on the new filter frame.
• Install it in the same direction as the old one came out (airflow should point toward the blower/housing).
• If it fights you, don’t crush it—re-align.

Step 8: Reinstall the door and glove box

• Reinstall the filter door. If it uses screws, tighten them using the 7mm socket and 1/4" drive ratchet (snug only—do not overtighten plastic).
• Reconnect the damper arm (if equipped) by pressing it back onto its peg by hand.
• Swing the glove box back up and push in the sides again to pass the stops back into place.

✅ After Repair

• Start the car and run the fan at all speeds to confirm strong airflow and no rattles.
• Turn on A/C for 1 minute and make sure there’s no whistling (a sign the filter isn’t seated).
• If airflow is still weak, the old filter may have left debris in the housing—recheck seating.
