🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and support the glove box

• Use the LED inspection flashlight to look along both inner sides of the open glove box.
• Support the bottom of the glove box with one hand.
• Locate the small damper arm on the right side. The damper slows the glove box as it opens.

Step 2: Disconnect the glove-box damper

• Use your fingers to slide the loop on the damper arm off the glove-box pin.
• Do not pull the arm sharply or pry it with a tool.
• Keep one hand under the glove box.

Step 3: Release the glove-box stops

• Use both hands to press the left and right sides of the glove box inward.
• Continue pressing until the molded stops clear the dashboard opening.
• Carefully rotate the glove box downward. Leave it attached at its lower hinges.

Step 4: Remove the filter-access cover

• Use the LED inspection flashlight to locate the rectangular cabin-filter cover behind the glove box.
• Use your fingers to squeeze the locking tabs on the cover.
• Pull the cover straight outward and set it aside.
• No fasteners are removed, so there is no torque specification for this repair.

Step 5: Remove the old cabin air filter

• Wear safety glasses and nitrile work gloves.
• Use your fingers to pull the old filter straight out without shaking it.
• Notice the direction of the airflow arrow printed on the old filter.
• Use the HEPA shop vacuum with crevice attachment to remove loose debris from the housing opening. Do not push the attachment deeply into the HVAC case.

Step 6: Install the new filter

• Use your hands to slide the new cabin air filter into the housing.
• Install it with the AIR FLOW arrow pointing downward.
• Keep the filter straight and avoid crushing or folding its pleats.
• Never force the filter into the housing.

Step 7: Reinstall the access cover

• Use your fingers to align the filter-access cover with the housing.
• Press the cover into place until both locking tabs click securely.
• Gently pull on the cover to confirm it is latched.

Step 8: Reinstall the glove box

• Use both hands to raise the glove box toward its normal position.
• Press both sides inward until the molded stops pass into the dashboard opening.
• Use your fingers to reconnect the damper-arm loop to the pin on the right side.
• Slowly open and close the glove box to confirm that it moves smoothly.

✅ After Repair

• Start your Sonata and run the blower through each fan speed.
• Confirm that air flows normally and no rattling or fluttering noise comes from behind the glove box.
• If airflow is restricted or noisy, switch the blower off and verify that the filter is seated flat with its airflow arrow pointing downward.
• Check the filter about every 12 months or 12,000-15,000 miles. Inspect it more often in dusty conditions.
