Hi. Yes I have a suggestion. The most common problem for the windows not to work on an Explorer is a broken wire in the drivers door harness. The harness that connects the door to the body. Look inside there for a broken wire and let me know what you find.
Ok. The other end is definitely there. You will need to give yourself enough room to strip back the wires and reconnect them. Usually they break in the middle of the harness. Its not the easiest to access but now that you know whats wrong with it you can repair it. On my 04 Explorer I had to take off the drivers door panel and disconnect some of the wiring and pull the harness out a little bit to get better access. Feel free to ask any further questions.
I found the other end. It is a blue and black wire. Is the door panel held on by clips, screws or both?
Hold on. I'll give you the procedure from the manual.

Could I access by just taking off the speaker cover then removing the speaker. It looks like he wires run behind the speaker
