🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and Empty the Glove Box

• Use your hands to open the glove box fully.
• Remove all papers, manuals, and loose items from the glove box.
• Use a flashlight to look along both inside edges of the glove box.
• Keep loose items away from the dash opening.

Step 2: Release the Glove Box Side Stops

• Use your hands to locate the round glove box stop knobs on the left and right inner sides.
• Turn each stop knob counterclockwise about a quarter turn, then pull it inward to remove it.
• A glove box stop is a small plastic limiter that keeps the glove box from dropping too far.
• Set both stops in a safe place so they do not roll away.

Step 3: Disconnect the Glove Box Damper

• Use your hand to find the small damper arm on the right side of the glove box.
• A damper is a small slow-drop arm that keeps the glove box from falling open quickly.
• Gently slide or unclip the damper arm from the glove box peg.
• Let the glove box swing down slowly.

Step 4: Remove the Cabin Filter Cover

• Use the flashlight to find the rectangular cabin filter cover behind the glove box opening.
• Use your fingers to squeeze the locking tabs on the cover.
• Pull the cover straight off and set it aside.
• No torque spec applies because there are no bolts or screws.

Step 5: Remove the Old Cabin Air Filter

• Use your fingers to slide the old cabin air filter straight out of the housing.
• Pay attention to the airflow arrow printed on the old filter before removing it fully.
• The airflow arrow should point in the same direction when the new filter goes in.
• Use a shop vacuum with crevice nozzle to gently remove leaves or dust from the opening.
• Do not push debris deeper into the housing.

Step 6: Install the New Cabin Air Filter

• Use your hands to slide the new cabin air filter into the slot.
• Match the airflow arrow direction to the original filter orientation.
• Keep the filter flat as it slides in so it does not fold or buckle.
• Make sure the filter is fully seated inside the housing.

Step 7: Reinstall the Filter Cover

• Use your hands to position the cabin filter cover over the opening.
• Press the cover until the locking tabs click into place.
• Lightly tug the cover by hand to confirm it is secured.

Step 8: Reattach the Glove Box

• Use your hand to reconnect the damper arm to the peg on the right side of the glove box.
• Lift the glove box back into position.
• Use your hands to reinstall both side stop knobs.
• Turn the stop knobs clockwise until they lock in place.
• Close the glove box and confirm it opens and closes smoothly.

✅ After Repair

• ✅ Start your Tucson and turn the blower fan on low, then medium, then high.
• ✅ Listen for rattles or fluttering sounds, which may mean the filter is not seated flat.
• ✅ Check that airflow from the vents feels normal.
• ✅ If the air still smells musty, the evaporator case may need HVAC deodorizing service.
• ✅ Replace the cabin air filter about every 12,000-15,000 miles, or sooner in dusty areas.
