I'm having what seems to be a not-so-uncommon problem in my 90 Accord,
where it overheats if not moving enough. After having cooling work
done, with the accompanying pressure test coming out ok (and most of
the system now replaced in the past year and a half), I checked the
cooling fan fuse. Blown. Replaced it, turned on the car, that fuse blew
immediately. What's the likely culprit? How much should the fix cost me?

=======================


The fan motor bushings are dry (worn out probably) Try spinning the fan
by hand. Brushes might be worn to nothing and shorting too.

If you turn on the car and the fuse blows immediately, then this could
mean a bad switch and/or relay (which can wear out your motor's
slip ring prematurely and create a short, as Curley mentioned.)
You might want to unplug the relay. If the fuse still blows then the
short is before the relay.
