One common problem with electrical gremlins is that the aluminum fuses have a dissimilar-metal corrosion problem with the brass fuse holder. A temporary fix is to 'spin' the fuses in their holders, breaking loose the corrosion.
Before you do this job, go to the auto parts store and get a packet or two of clectrical contact grease. These should be very inexpensive.
The cure for this is to remove each fuse, one at a time, and buff the ends with a heavy cloth (canvas or denim). Before you put each fuse back in, put a tiny dab of the contact grease on each end. This prevents air and moisture from getting to the contact points, eliminating future corrosion.
There are fuse kits available with brass tipped fuses, rather than aluminum, but some people have reported difficulty finding them.
