Sorry for the delayed response, but haven't had much time to work on the Expedition since moving into a new house. No, I have not checked the GEM module. I did notice when I went under to check the shifter motor that my connector has 11 wires pinned into it instead of 7 that are on the one a local parts dealer gave me to try in it's place. I am assuming the difference is the AWD vs standard 4WD.
