🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box and remove anything inside so it doesn’t fall out.
• Use nitrile gloves if you’re sensitive to dust.

Step 2: Release the glove box dampener (the slow-down strap)

• On the right side of the glove box, locate the small dampener arm (it controls how the glove box lowers).
• Use a plastic trim removal tool (specialty) to gently pry it off its pin if it’s tight.
• Go slow—plastic tabs can snap.

Step 3: Let the glove box swing fully down

• Press in on both sides of the glove box to clear the side stops.
• Lower the glove box until it hangs down, giving access behind it.
• Use a flashlight to clearly see the filter access door.

Step 4: Remove the cabin filter access door

• Find the rectangular cover directly behind the glove box.
• Pinch the tabs on the sides of the cover and pull it straight off by hand.
• If your cover uses screws on your Tucson, remove them with a Phillips screwdriver #2 first.

Step 5: Remove the old cabin air filter

• Slide the filter straight out of the housing.
• Keep it level to avoid dumping leaves/dust.
• Use safety glasses if debris is falling.

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

• Look for the airflow arrow on the filter frame.
• Install it with the arrow pointing down (toward the floor), which is the normal airflow direction on your Tucson.
• Slide it in smoothly—don’t crush or bend it.

Step 7: Reinstall the cover and glove box

• Reinstall the filter access door until both side tabs click.
• Lift the glove box back up and press the sides in to pass the stops again.
• Reattach the dampener arm on the right side by pushing it back onto its pin by hand (use the plastic trim removal tool (specialty) only if needed).

✅ After Repair
