When I first bought my 2003 7.3 I had no power windows, and no self-activated dome lights (as well as no radio). I checked the 30A circuit breaker, the power window relay, and the main drivers door switch all to no avail.
Then I found a 10A fuse that was popped (located under the relay's, can't recall the number off hand that was on a totally unrelated circuit. When I jumped it with a wire, the wire got super hot, and I heard hissing and smelled burning almost immediately (but in that 1/2 second or so the windows worked.) I checked it again, turned out the burning was coming from behind the fuse box. In my case, it turned out that a short had developed between two pins in my fuse box and it ended up I had to replace the fuse box via ford (or spend hours of my life trying to resolder a pin to the circuit board in the back of the panel that was related to my ignition.
I spent 2 hours looking for a used fuse panel online and via phone but got no joy on finding one for my lovely but rare 03 7.3L standard trans truck within 500 miles. Your symptoms sound similar at a glance so I would check EVERY single fuse first as there are a few related circuits that are NOT noted in the owners manual. Replace any broken ones, hopefully you don't need a fuse panel or gem (not sure what that is) like I did but I'd search all the fuses before looking elsewhere.
