    The auto headlight, the inside light when I open the door not working and the radio will stay on after turning off the car and opening the door. My car is 2003 ed. Everything was working normal a night before that what I noticed so far. I checked the fues and all of them are good. I am thinking it might be the Gem contral. Any ideas?

    your 03 expedition DOES NOT have a gem module
    Sounds like the problem may be the door switch.
    Can you read and understand electrical diagrams?
    Do you have any electrical test equipment ie: DVM, Test Light?
    Does this happen with all the doors or just one door?

    I am not that good with the diagrams but maybe you can walk me through it. I have a test light and I can get a DMV but also I am not that good with it.

    I checked all doors and lift gate NO ajar warning light.

    bare with me on this

    Make sure all doors are closed.
    Start the expy then shut it down and remove the key
    DO NOT open the doors but see if your windows operate after you shut if off and remove key

    you say you checked the fuses.
