🔨 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 contents from the glove box.
• Use a flashlight to look at both inner sides of the glove box.
• Keep small items in a cup.

Step 2: Release the Glove Box Damper

• Use your hands to locate the small damper arm on the right side of the glove box.
• The damper is a small plastic arm that slows the glove box as it opens.
• Gently slide or unclip the damper arm from the glove box pin.
• Do not pull hard; the plastic clip can crack.

Step 3: Remove the Glove Box Side Stops

• Use your hands to squeeze both sides of the glove box inward.
• The side stops are molded tabs that prevent the glove box from opening too far.
• While squeezing inward, lower the glove box carefully toward the floor.
• No bolts are removed for this step, so no torque spec applies.

Step 4: Open the Cabin Filter Cover

• Use your flashlight to find the rectangular cabin filter cover behind the glove box opening.
• Use your fingers to press the cover tabs inward.
• Pull the cover straight out and set it aside.
• Tabs release easier with gentle pressure.

Step 5: Remove the Old Cabin Air Filter

• Use your hands to slide the old cabin air filter straight out.
• Keep the dirty side facing up or level so debris does not fall into the HVAC box.
• The HVAC box is the plastic air duct housing behind the dash.
• Use nitrile gloves and a dust mask if the filter is dusty or moldy.

Step 6: Install the New Cabin Air Filter

• Use your hands to position the new cabin air filter with the airflow arrow pointing downward.
• Slide the new filter into the slot evenly.
• Do not crush or fold the filter pleats.
• Make sure the filter sits flat inside the housing.

Step 7: Reinstall the Cabin Filter Cover

• Use your hands to align the cabin filter cover with the housing.
• Push the cover into place until both tabs click securely.
• Lightly tug the cover with your fingers to confirm it is locked.

Step 8: Raise and Reconnect the Glove Box

• Use your hands to lift the glove box back into position.
• Squeeze the glove box sides inward again so the side stops pass the dash opening.
• Reconnect the right-side damper arm by sliding or snapping it back onto its pin.
• Open and close the glove box once to confirm smooth movement.

Step 9: Test the HVAC System

• Start your Tucson or turn the ignition to accessory mode.
• Use the climate control buttons to turn the fan on low, then medium, then high.
• Listen for rattles or whistling that could mean the filter cover is not fully latched.
• No scan tool or reset is required after cabin air filter replacement.
