🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glovebox

• Open the glovebox fully by hand.
• Remove all items so you can safely lower the glovebox later.
• Use a small flashlight to see the right-side damper and filter cover.

Step 2: Release the glovebox damper (right side)

• On the right side of the glovebox, find the small “damper” arm (a soft-close link that slows the glovebox).
• Carefully pop the damper arm off its pin by hand. Go slow—don’t pry hard.

Step 3: Lower the glovebox by releasing the side stops

• Push inward on the left and right sides of the glovebox to clear the rubber/plastic stops.
• Let the glovebox swing downward gently.
• Wear nitrile gloves if you’re sensitive to dust.

Step 4: Remove the cabin filter access cover

• Behind the glovebox, locate the rectangular cabin filter cover.
• Press the cover’s locking tabs (usually one on each side) and pull the cover straight off by hand.
• Use a small flashlight to confirm the tabs are fully released before pulling.

Step 5: Remove the old cabin air filter

• Slide the old filter straight out toward you.
• Keep it level to avoid dumping leaves/dust into the blower housing.
• Use safety glasses to protect your eyes from falling debris.

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

• Check the airflow arrow printed on the filter frame.
• Install the new filter with the airflow arrow pointing down (toward the floor), which matches the typical airflow direction on your Tucson.
• Slide it in until it seats fully—do not crush or fold the filter.

Step 7: Reinstall the cover and glovebox

• Reinstall the cabin filter cover by hand until both tabs click into place.
• Lift the glovebox back up and push the sides inward again to pass the stops back into position.
• Reconnect the right-side damper arm onto its pin by hand.
• Open/close the glovebox a few times to confirm it moves smoothly.

✅ After Repair

• Start your Tucson and run the blower at medium/high for 30 seconds.
• Confirm airflow is stronger and there are no rattles behind the glovebox.
• If you still smell musty odor, consider an A/C evaporator cleaner service next.
