The heat is generated by resistance at the contacts.
Heat is proportional to
the current squared times the resistance, so for high
current circuits like
a fan, its key to avoid resistance. Clean out the old
plastic and emery
cloth (lightly sand) the contacts.
If the contacts are loose (are they floppy loose, or
just bent away from the
correct position?), that needs to be fixed. The
contacts need to press
against the fuse contacts. You can make a temporary
fix using a rubber band,
but that will fail over time as the rubber gets old.
You can probably remove
the fuse box cover - after disconnecting ground at the
battery, and see if
the contacts for the fuse just warped from the heat or
need to be replaced.
Ypu may be able to bend themback without removing the
cover, it'll depend on
your tools, access and skill level. Be careful bending
them too much as the
bending causes the metal to "work harden" i.e. get
brittle, and after a
couple cycles, it'll break.
