Somebody might have some insight about the condition but it's not me. I would have to get out a wiring diagram and trace the circuit on the fuse you mention. Check the easiest and most suspect things along the circuit and then move to others if necessary. It sounds like a break or corrosion along parallel lines involving a short and cross current. I also suggest you subscribe to alldatadiy.com. There you can get on-line diagnostics for you car... including wiring diagrams.
