How do you change the cabin air filter on a 2003 Ford Expedition?

Answer 1

Locate the cabin air filter container on your Ford Expedition. If you are standing in front of the vehicle, looking at the engine, it will be on the back, left side of the engine, next to the heater fan. You will see a black cover over the top of the container. The air filter is approximately 6" x 9" and about 2" deep. Look for a black casing that will be about 10" across and 8" high. The box sits vertically against the firewall of the vehicle.

Step 2

Remove the cover of the cabin air filter by lightly prying on it with a screwdriver. The cover is secured with plastic tabs that pop off quite often. If this happens, you can buy replacements at your local automotive store.

Step 3

Remove the cabin air filter, and vacuum out the container to remove any dust or debris. Wipe it down with a clean damp cloth and let the inside of the container dry before inserting new filter.

Step 4

Place new cabin air filter in container and secure the cover, replacing tabs if needed. Remove tools from engine compartment and close hood.

Step 5

You are now able to enjoy driving with clean air flowing through the inside of your car.

FYI, you will only have a cabin filter if the dealership has installed an optional add-on. Most of the people I have spoken with do NOT have this filter installed. I went crazy looking for it until I found this out.
