🔨 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 locate the right-side glove box damper (a small arm/strap that slows the glove box).

Step 2: Disconnect the glove box damper

• On the right side, gently pop the damper arm off its peg.
• If it’s tight, use a plastic trim removal tool (non-marring) to carefully pry it free.
• Go slow—plastic bends before it breaks.

Step 3: Drop the glove box down

• Push in on both sides of the glove box to clear the side stops.
• If needed, use a small flathead screwdriver to gently help the stops past the dash opening (don’t gouge the plastic).
• Let the glove box swing downward toward the floor.

Step 4: Remove the cabin filter cover

• Behind the glove box you’ll see the cabin filter housing cover.
• Use your fingers (or a plastic trim removal tool (non-marring)) to release the tabs and remove the cover.

Step 5: Remove the old cabin air filter

• Pull the filter straight out by hand.
• Use a flashlight to check the housing for leaves or debris.
• If you see debris, wipe it out carefully by hand (with nitrile gloves) so it doesn’t fall deeper into the blower.

Step 6: Install the new cabin air filter

• Check the airflow direction marking on the filter (often an “AIR FLOW” arrow).
• Install it the same direction as the old one came out.
• Slide it in evenly—don’t force it or bend it.

Step 7: Reinstall the cover and glove box

• Reinstall the cabin filter cover by hand until the tabs click into place.
• Lift the glove box back up and push the sides inward so the stops go back into position.
• Reconnect the right-side damper arm by hand until it snaps back on.

✅ After Repair

• Switch between fresh air and recirculation to confirm the HVAC operates normally.
• If you notice a musty smell at first, it may clear after a few minutes of running the fan.
