🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box fully and remove all contents by hand.
• Use a flashlight so you can clearly see the right-side arm and the filter cover area.

Step 2: Unhook the glove box damper (right side)

• On the right side of the glove box, locate the small “damper” arm (a little shock/strap that slows the glove box). Damper = the small arm that controls drop speed.
• Use a trim panel tool (plastic pry tool) to gently pop the damper arm off its pin (it should release with light pressure).

Step 3: Drop the glove box down

• With the damper detached, push the glove box sides inward by hand to clear the built-in stops.
• Let the glove box rotate downward carefully until you can see the rectangular cabin filter housing behind it.

Step 4: Remove the cabin filter cover

• Locate the rectangular cover on the HVAC box behind the glove box.
• Release the cover tabs by hand; if it’s tight, use the trim panel tool (plastic pry tool) gently at the tab area.

Step 5: Remove the old cabin filter

• Pull the old filter straight out using your hands (wear nitrile gloves; it can be dusty).
• Keep the filter level as you remove it to avoid dumping debris.

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

• Check the airflow arrow on the filter frame.
• Install the new filter with the airflow arrow pointing in the same direction as the old one (usually “DOWN” toward the floor on this setup).
• Slide it in until it seats evenly—don’t crush or fold it.

Step 7: Reinstall cover and glove box

• Reinstall the housing cover by hand until the tabs click into place.
• Lift the glove box back up and push the sides inward again to pass the stops.
• Reattach the damper arm on the right side by pressing it back onto its pin by hand.
• If any small screws were removed on your setup, reinstall using a Phillips #2 screwdriver (snug only; do not overtighten into plastic).

✅ After Repair

• Start the engine and run the fan on medium speed; confirm airflow feels normal and there are no rattles.
• If you notice a whistling noise, the filter may not be fully seated—recheck the cover and filter alignment.
• Write the date/mileage on the filter edge.
