🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box and remove any contents by hand.
• Use a flashlight to look along the right side of the glove box for the small “dampener” arm.
• Go slow—most parts are just clips.

Step 2: Disconnect the glove box dampener

• The dampener is a small arm that slows the glove box as it drops (it prevents it from slamming).
• Use a trim removal tool (plastic) to gently pry the dampener arm off its pin on the glove box (or unhook it by hand if it slips off easily).

Step 3: Drop the glove box down

• Push in on both sides of the glove box near the upper corners to clear the side “stops.”
• Once the stops pass the dash opening, let the glove box swing downward.
• If there’s a small side pin/strap still holding it, use the trim removal tool (plastic) to gently release it.

Step 4: Remove the cabin filter access cover

• Behind the glove box, locate the rectangular cabin filter housing.
• Use a flashlight to find the housing cover tabs.
• Release the tabs by hand; if they’re tight, use a trim removal tool (plastic) carefully.
• If your cover uses screws (some do), remove them with a Phillips screwdriver.

Step 5: Remove the old filter

• Pull the old cabin filter straight out by hand.
• Wear nitrile gloves—it can be dusty.
• Use the flashlight to check for leaves/debris inside the housing and remove what you can by hand.

Step 6: Install the new filter (correct direction)

• Look for an airflow arrow on the filter frame.
• Install the filter so the arrow points in the direction of airflow (toward the blower motor/into the HVAC housing).
• Slide it in evenly so it doesn’t bend or snag.

Step 7: Reinstall the cover and glove box

• Reinstall the cabin filter cover until the tabs click in (or tighten screws with a Phillips screwdriver if equipped).
• Lift the glove box back up and push the sides in to get the stops back past the dash opening.
• Reattach the glove box dampener arm by pressing it back onto the pin by hand (use the trim removal tool (plastic) only if needed).

✅ After Repair

• Start the engine and run the fan on medium-high for 30 seconds.
• Confirm airflow is stronger and there are no rattles behind the glove box.
• If you notice a musty smell, run the A/C for a few minutes to help dry the HVAC box.
