Any idea where the fuse is that works the roof skylight?
What is engine litre size? My info just shows expedition, doesn't say eddie bauer. In the diagram, at the top, note the fuse and circuit breaker, they are located in underhood fuse box. Hopefully the fuse box lid has a legend on it, that will tell you which fuse or circuit breaker does what? If not your owners manual should show this info. Use a test light to check for voltage at fuse and circuit breaker. Can you check applicable trouble codes? Some of the national brand autostores will check codes for free, if there are any. There could be many different issues causing this problem?
