To fix the problem you need to replace the fan switch (or repair it -- but
if you could repair it you wouldn't be asking the question).  If you get a
used one, I recommend getting one from a *rear* blower (same switch) b/c
most of the front ones have or are about to have your same problem.  The
heater-control faceplate has to come off to remove the switch.  Plastic
lugs at bottom-left and top-right that stick into spring-loaded holes in
the dash.  Control handles pull off the levers first -- probably should
warm them up; and be careful not to catch the handle on the faceplate as it
comes out.

To keep it from happening again, add a separate circuit to power the
high-speed position on the fan, and use the high-speed wire from the switch
to drive the relay.  That way the switch has almost no load at high speed,
and can easily handle the draw at lower speeds.
