🔨 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 items from the glove box and set them aside.
• Use a clean shop towel to wipe away loose dust around the glove box opening.
• Keep small items in a cup.

Step 2: Release the Glove Box Stops

• Use your hands to gently press inward on both sides of the glove box.
• The glove box stops are small molded plastic tabs that prevent the glove box from dropping too far.
• While pressing both sides inward, lower the glove box down toward the floor.
• Do not yank it. Let it drop slowly once the stops clear the dash opening.

Step 3: Locate the Cabin Filter Access Door

• Use the flashlight to look behind the lowered glove box.
• Find the long, narrow rectangular plastic cover on the HVAC housing.
• The HVAC housing is the black plastic air box that routes air for heat and air conditioning.

Step 4: Remove the Filter Access Door

• Use your fingers to press the retaining tab on the cabin filter access door.
• Pull the door straight outward and remove it.
• Place the door somewhere safe so it does not get stepped on.
• No torque spec applies because this cover clips on and has no bolts.

Step 5: Remove the Old Cabin Air Filter

• Use your fingers to slide the old cabin air filter straight out of the slot.
• Hold it level so leaves, dust, and dirt do not spill into the blower area.
• Use a clean shop towel to catch loose debris near the opening.
• Do not use compressed air inside the HVAC case; it can push debris deeper into the system.

Step 6: Check Airflow Direction

• Look at the side of the old cabin air filter for an airflow arrow.
• Check the new cabin air filter for the same arrow marking.
• Install the new filter with the airflow arrow pointing in the same direction as the old filter.
• On your Ranger, the filter slides into the HVAC case behind the glove box.
• Match the arrow before sliding it in.

Step 7: Install the New Cabin Air Filter

• Use your hands to carefully slide the new cabin air filter into the filter slot.
• Keep the filter flat and straight so the pleats do not fold over.
• If it feels stuck, pull it back out and realign it. Do not force it.

Step 8: Reinstall the Filter Access Door

• Use your hands to position the plastic access door over the filter opening.
• Press it into place until the retaining tab clicks.
• Gently tug on the cover with your fingers to confirm it is locked in place.
• No torque spec applies because this cover clips on and has no bolts.

Step 9: Raise the Glove Box

• Use your hands to lift the glove box back upward.
• Press the sides inward slightly so the glove box stops pass back through the dash opening.
• Release the sides and make sure the glove box opens and closes normally.

Step 10: Refill the Glove Box

• Use your hands to place your items back into the glove box.
• Close the glove box and check that it latches securely.
