Driver side power visor fuse location

2007 Winnebago 38J.

The Drivor Sunvisor has ceased working.

Can anyone tell me how many fuses may be involved, their location, and how to identify them.

I have power to the switch, I think the next step is to check at the fuses.

Hopefully it is not a motor issue.

Maybe loose connnections at the visor - but I hope not.
