🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box fully and remove manuals and loose items by hand.
• Use a small flashlight to look at the right side of the glove box for the small “damper” arm (a slow-open strap).

Step 2: Disconnect the glove box damper arm

• Use a trim removal tool (plastic) to gently pry the damper arm off its peg on the glove box (it pops off).
• Go slow—this clip is easy to snap.

Step 3: Drop the glove box down

• Press inward on both sides of the glove box (near the top) with your hands to clear the side stops.
• Let the glove box swing downward toward the floor.

Step 4: Remove the cabin filter access door

• Behind the glove box opening, locate the rectangular cabin filter cover.
• Release the cover tabs by hand (or use the trim removal tool (plastic) gently) and remove the cover.

Step 5: Remove the old cabin air filter

• Pull the filter straight out by hand.
• Keep it level to avoid dumping leaves and dust into the blower area.

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 (typically AIR FLOW arrow points down toward the floor on this setup).
• Slide the filter in until it seats fully—no bending or forcing.

Step 7: Reinstall the cover and glove box

• Reinstall the access door by hand until the tabs click into place.
• Lift the glove box back up and press inward on both sides to pass the side stops back into position.
• Reconnect the damper arm by pressing it back onto its peg by hand.

✅ After Repair

• Start the engine and run the fan at all speeds to confirm strong airflow and no rattles.
• Switch between fresh air and recirculate to confirm the glove box area stays quiet.
