Owners of other Ford or Lincoln vehicles such as the Explorer, F-150, Escape, EcoSport, Transit, F-350, F-250, Edge, Flex, Ranger, Fiesta, Focus, Fusion, Mustang, Bronco, Super Duty, Navigator, Continental, MKZ, MKX, MKC, MKT, Aviator, Corsair and Nautilus may also find these DIY instructions to be helpful.

A few compatible replacement cabin air filters with their part numbers include the following: Spearhead BE-150, Fram CF12150, Premium Guard PC8214X, EcoGard XC10491, K&N VF2049 and TYC 800198P.

The tools needed to access and replace the filter include a 7mm socket and a 1/4" drive ratchet.

The first two steps are to open the glove box and empty out the contents.

Locate the damper arm on the right outer side wall of the glove box.

Then pull the damper arm's mounting button out of the right side wall of the glove box.

Push the chrome silver button to open the top storage compartment.

Empty out any contents of the storage drawer.

Firmly pull the top storage compartment out of the dashboard.

It is held in place by a few metal friction fastener clips.

Set the top storage compartment aside in a safe place.

Pull the lower storage compartment out of the glove box.

You may need to wiggle the compartment and use some force to remove it from the dashboard.

Locate the electrical connector for the glove box light bulb.

Set the lower storage compartment aside in a safe place.

Once the glove box, upper storage compartment and lower storage drawer have all been removed, you'll be able to see the HVAC blower motor housing and the filter access cover.

Then release the retaining clip on the right side of the filter cover.

Try to avoid bending the retaining clips out too far to prevent from breaking them.

Swing open the top of the filter cover and then lift out the two tabs on the bottom edge.

Slide the old filter straight out of the slot in the HVAC blower motor housing.

If the old filter is dark grey or black and clogged with dirt, dust, sand, hair, pollen, insects, leaves, twigs, soot and other debris, it should be replaced with a new element.

I recommend buying the Spearhead BE-150 cabin air filter since it has excellent reviews on Amazon.

If you would like to have a more environmentally friendly washable and re-usable filter, choose the K&N VF2049 filter.

Check the filter slot in the HVAC blower motor housing for any large debris.

Clean out any debris in the slot with a crevice attachment on your vacuum cleaner.

Make sure the new filter is fully seated in the slot.

First, re-insert the two tabs on the bottom edge into their corresponding slots.

Then push on the top edge to secure the two retaining clips.

You should feel and/or hear the clips "click" securely into place.

If any of the friction fasteners from the two storage compartments remained attached to the dashboard, pull them out and re-attach them to the back of the storage compartments.

Push the electrical connector for the glove box light bulb back into its socket.

You should feel or hear the connector "click" securely into place.

Carefully push the lower storage drawer back into the dashboard to secure the friction fasteners.

Try to avoid over tightening the screws to prevent from cracking the plastic storage compartment assembly.

Push on the compartment to secure the friction fasteners.

Re-insert the rubber trim pieces on each side of the storage drawer back into place.

Firmly push in the two side walls until the rubber side stops can be re-inserted behind the dashboard.

Re-insert the mounting button on the damper arm into the larger hole on the right side of the glove box.

Then push the arm forward (towards the front of the car) to pop the button into the smaller hole.

Double check that the damper arm is securely attached to the glove box.

Replace the contents of the glove box and close it to complete the procedure.

Enjoy the fresh clean air from your A/C system!

The service interval specification in the owner's manual for the cabin air filter is to replace it at least every 20,000 miles. I also recommending checking and cleaning the filter at every oil change (every 10,000 miles or 1 year).

Be sure to write down the filter change in your vehicle's service records.
