You're welcome.  Now if you want the new switch to last, run another 16-amp
fused circuit from the 15-circuit (i.e. ignition-switched circuit) at the
panel to a relay (30/88 terminal) and use that to drive the high-speed
position of the fan.  Cut the wire from the switch -- use the switch end to
drive the relay (pin 85 or 86 -- ground the other one) and the load end to
take power from pin 87/88a.

By this method the low fan speeds are handled by the original circuit which
can easily handle them, but the high speed is supplied separately with the
switch providing only the activation current for the relay.  Should last
forever.
