🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Empty and open the glovebox

• Remove everything from the glovebox by hand so nothing falls out.
• Open the glovebox fully and use a flashlight to look at the right side.

Step 2: Disconnect the glovebox damper

• On the right side of the glovebox, locate the small “damper” arm (it slows the glovebox when it opens).
• Use a plastic trim removal tool set to gently pop the damper arm off its pin.
• Gentle pry only—no twisting hard.

Step 3: Release the glovebox stops and lower it

• Use both hands to squeeze the glovebox sides inward to clear the side “stops” (tabs that prevent it from dropping).
• If a stop is tight, use a plastic trim removal tool set to help guide the tab past the dash opening.
• Let the glovebox swing down carefully.

Step 4: Remove the cabin filter access cover

• Behind the lowered glovebox, find the rectangular cabin filter cover.
• Use a plastic trim removal tool set to press the locking tabs and pull the cover off.
• If your cover uses screws on your A/C case, remove them with a Phillips #2 screwdriver.

Step 5: Pull out the old cabin filter

• Wear nitrile gloves and slide the old filter straight out.
• Use a flashlight to check for leaves/debris inside the housing.
• If needed, wipe the opening with a dry shop towel (use the nitrile gloves).

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

• Check the airflow arrow on the new filter frame.
• Install it in the same direction as the old one (the arrow must match airflow direction shown on the housing/cover).
• Slide it in evenly—don’t crush or fold the filter.

Step 7: Reinstall the cover and glovebox

• Reinstall the access cover until the tabs click in place, using a plastic trim removal tool set to help align if needed.
• If screws were removed, reinstall with a Phillips #2 screwdriver (snug only; do not overtighten).
• Lift the glovebox back up and push the sides inward by hand to re-seat the stops.
• Reconnect the damper arm using the plastic trim removal tool set to guide it onto the pin.

✅ After Repair

• Start the engine and run the blower fan on high for 30 seconds.
• Switch between fresh air and recirculate to confirm airflow feels normal.
• Listen for rattles behind the glovebox; if you hear one, recheck that the filter cover tabs are fully latched.
