This also happened recently on my '87 after running the fan on high for an
extended period.  I pulled the dash switch and found that the contacts had
melted and were stuck in the high speed position.  I cleaned the terminals
and replaced the switch.  All if fine now but I wonder if I might have
dirty terminals somewhere else in the circuit as well.
