🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Empty and Open the Glove Box

• Use your hands to open the glove box fully.
• Remove all papers, manuals, and loose items from inside.
• Use a flashlight to look along the sides of the glove box opening.
• Put small items in a cup.

Step 2: Release the Glove Box Stops

• Use your hands to gently push inward on both side walls of the glove box.
• While squeezing the sides inward, lower the glove box past the built-in stops.
• If the plastic feels stiff, use a trim removal tool gently at the side stop area to help guide it inward.
• Do not yank on the glove box; it should lower smoothly once the stops clear the dash opening.

Step 3: Lower the Glove Box

• Use your hands to let the glove box hang downward carefully.
• Use the flashlight to look behind the glove box area.
• The cabin filter access door is a narrow rectangular cover on the HVAC housing behind the glove box.
• The HVAC housing is the plastic air box that directs air through the heater, A/C, and vents.

Step 4: Remove the Cabin Filter Cover

• Use your fingers to release the tabs on the cabin filter cover.
• If a tab is tight, use the trim removal tool gently to press the locking tab while pulling the cover outward.
• Set the cover aside where it will not be stepped on.
• No torque spec applies because this cover uses plastic clips, not bolts.

Step 5: Remove the Old Cabin Air Filter

• Use your fingers to slide the old cabin air filter straight out of the housing.
• Use safety glasses because dust or leaves may fall as the filter comes out.
• Look at the airflow arrow printed on the old filter before removing it completely.
• On your Fusion, install the new filter with the airflow arrow pointing the same direction as the original filter.
• Take a quick photo first.

Step 6: Clean the Filter Slot

• Use a flashlight to inspect the empty filter slot.
• Use gloved fingers to remove any large leaves or debris you can easily reach.
• Do not push debris deeper into the HVAC housing.
• Do not spray cleaner into the filter slot during this basic filter replacement.

Step 7: Install the New Cabin Air Filter

• Use your hands to slide the new cabin air filter into the housing.
• Keep the filter straight so the pleats do not fold over.
• Make sure the airflow arrow matches the direction of the original filter.
• The filter should sit fully inside the housing without sticking out.

Step 8: Reinstall the Cabin Filter Cover

• Use your hands to place the filter cover back onto the HVAC housing.
• Press until the tabs click into place.
• Use the flashlight to confirm the cover is fully seated on both sides.
• No torque spec applies because the cover is retained by clips.

Step 9: Raise and Lock the Glove Box

• Use your hands to raise the glove box back toward the dash opening.
• Push inward slightly on the glove box sides so the stops pass back into position.
• Open and close the glove box once to make sure it moves normally.
• Reload your glove box items after confirming it latches correctly.
