I had the switch break on an '87 Civic once and it wasn't all that hard
to replace. However, when the lower fan speeds stop working and the
higher speeds still work, the problem is usually burned out resistors
rather than the switch. There is a set of 3 resistors in series that
drop the voltage to the fan at the lower speeds. Usually the resistor
pack is mounted close to the blower in such a way that the resistor are
in the air stream. If you find them, ohm them out and see if any of them
are broken. My bet is that the middle one is open.
