🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box fully and remove any contents by hand.
• Use a flashlight to look at the right side of the glove box for a small “dampener” arm (a small strap that slows the glove box as it opens).

Step 2: Disconnect the glove box dampener arm

• Carefully unhook the dampener arm from the glove box using your fingers.
• Tip: Support the glove box as you unhook it.

Step 3: Drop the glove box down

• With the glove box open, push inward on both sides of the glove box walls with your hands.
• This lets the side “stops” clear the dash opening so the glove box can swing down.
• Let the glove box hang down gently (don’t force it).

Step 4: Remove the cabin filter door

• Behind the glove box you’ll see a rectangular filter housing cover.
• Use your fingers to press the tabs and remove the cover.
• Use a flashlight to confirm the cover is fully disengaged before pulling.

Step 5: Remove the old cabin air filter

• Slide the old filter straight out by hand.
• Keep it level as you pull it out so leaves/dust don’t spill.
• Note the airflow direction marking on the filter (it’s usually an arrow). This arrow must point the correct way when you install the new one.

Step 6: Install the new cabin air filter

• Slide the new filter into the housing.
• Match the airflow arrow to the same direction as the old filter (and any arrow printed on the housing if present).
• Tip: If it won’t slide in, don’t crush it—recheck alignment.

Step 7: Reinstall the filter door and glove box

• Reinstall the housing cover by hand until the tabs click into place.
• Lift the glove box back up and push the sides inward again so the stops go back into position.
• Reconnect the dampener arm by hand on the right side.

✅ After Repair

• Start your Tucson and turn the fan to medium/high to confirm strong airflow and no rattles.
• Switch between fresh air and recirculation modes to make sure everything sounds normal.
• If you still smell musty odors, consider cleaning the intake area at the base of the windshield and checking for dampness in the passenger footwell.
