đź”§ Tucson - Cabin Air Filter Replacement
Your Tucson’s cabin air filter cleans the air going through the A/C and heater. Replacing it helps airflow, reduces musty smells, and keeps dust/pollen out of the cabin.
Difficulty Level: Beginner | Estimated Time: 0.2-0.5 hours
⚠️ Safety & Precautions
- ⚠️ Turn the ignition OFF and remove the key/fob from the vehicle.
- ⚠️ Don’t force plastic tabs—warm cabin plastics break less easily.
- ⚠️ Keep fingers clear of the glovebox hinge area when releasing stops.
đź”§ Required Tools

đź“‹ Before You Begin
- Park your Tucson on level ground and set the parking brake.
- Move the front passenger seat back for working room.
- Empty the glovebox so nothing falls out.
🔨 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.
âś… 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.
