start with the switch in the column and check it out.  it is about the
only thing i can think of that doesnt have everything else common to
blow the fuse.  the intermittant routes through a relay first and then
trips one of the windings (either the slow or the fast depending on
type).  but you state that it does it with either slow or fast so that
seems to leave the switch itself may have something a little loose or
something in against the contacts.
