Not had problems with fan but electrical issues generally - seems to be a problem with the blade fuses and making good contact - try cycling fuse in and out a few times to clean contact area.
I had serious problem with LH Headlamp - did this - came back went away - used contact cleaner - good for a few weeks ended up buying new fuses and twisting blade slightly to increase contact pressure (very slightly a couple of degrees) been ok now for 6 weeks
