I'm a first time Expedition owner of 2004 Eddie Bauer Expedition w 5.4L 2wd. I bought this 3 weeks ago from an individual on Facebook for $2800. My problem is that the third row seats, door locks,hatch glass and maybe other systems not yet found don't work. I checked the fuses for the seats. Checked the relays in the rear pillars d they all good. .please help
