🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and release the glove box

• Open the glove box fully.
• If your glove box has a small “damper” arm (a little shock/strap on the right side that slows the door), use a trim removal tool (plastic) to gently pop it off its pin. A damper is a small arm that prevents the glove box from dropping quickly.
• Press the glove box side walls inward by hand to clear the built-in stops, then let the glove box swing down.

Step 2: Remove the cabin filter cover

• Look behind the glove box for a rectangular access door (the filter cover).
• Use your fingers or the trim removal tool (plastic) to press the locking tabs and pull the cover straight off.
• Use a flashlight if needed to see the tabs clearly.

Step 3: Remove the old cabin air filter

• Pull the filter tray or filter straight out (some come out as one piece).
• Wear nitrile gloves and safety glasses since dust and debris can fall out.
• Tip: Keep it level to avoid spills.

Step 4: Install the new cabin air filter

• Check the airflow arrow on the filter frame.
• Install it in the same direction as the old one came out (match the arrow direction shown on the housing/filter).
• Slide the filter fully in until it seats evenly with no gaps.

Step 5: Reinstall the filter cover and glove box

• Snap the filter cover back on until both tabs click.
• Lift the glove box back up, press the sides inward again, and guide the stops back into place.
• If removed, reattach the glove box damper arm by pressing it back onto the pin.

✅ After Repair

• Start the engine and run the blower fan at different speeds to confirm normal airflow and no rattles.
• If you notice a musty smell, run the A/C for a few minutes; the new filter may help quickly, but heavy odor can indicate the evaporator case needs cleaning.
