🔨 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 glove box sides and back area.

Step 2: Release the glove box stops

• Press the glove box side walls inward with your hands to clear the “stops” (the little plastic bumps that prevent it from dropping all the way).
• Lower the glove box gently once the stops clear. Go slow so you don’t crack it.

Step 3: Disconnect the glove box damper arm

• On the right side of the glove box, locate the damper arm (a small piece that slows the glove box as it opens).
• Use a plastic trim removal tool to gently pry the damper arm off its pin/clip, then let the glove box hang down.

Step 4: Remove the cabin filter access cover

• Behind the lowered glove box, find the rectangular cabin filter housing.
• Press the tabs on the housing cover by hand (use the flashlight to see them clearly) and pull the cover straight off.

Step 5: Slide out the old cabin filter

• Pull the filter tray/filter straight toward you by hand.
• Wear nitrile gloves—this filter can be dusty.

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

• Look for the airflow arrow on the new filter frame.
• Install it with the airflow arrow pointing down (toward the floor), matching the housing’s airflow direction marking if present.
• Slide the filter/tray fully in until it seats evenly.

Step 7: Reinstall the cover and glove box

• Reinstall the filter housing cover by hand until both tabs click.
• Reconnect the damper arm using the plastic trim removal tool as needed to align it, then snap it back onto the pin/clip.
• Push the glove box sides inward again and raise it past the stops, then release.

✅ After Repair

• Start the engine and run the HVAC fan on medium to confirm strong airflow and no rattles.
• Switch between fresh air and recirculation to verify everything sounds normal behind the glove box.
• If you notice a musty smell, run the fan for a few minutes with A/C off to dry the ducts.
