Where's the cabin air filter?
Hi 2000expy. It is generally located in the exterior cold air intake. Here's a link to a rather hefty .pdf that shows how to change the cabin filter on several cars including I believe your Expedition. Hope it helps! Good luck! http://www.boschautoparts.com/NR/rdonlyres/425B1A4D-5155-4064-A5E7-E07F8DB720C7/0/CabinAirFilterInstallation.pdf
