The point is, that if the resistor blows then something is probably wrong
with your fan. Even if the Jeeps whole resistor pack magically
disintigrated, its a cheap easy part to replace. What caused the failure is
the issue here.

FWIW my old Ford Escort ('91) was the same way.
On that one, though, I had the connector contacts corrode instead of
the fuse blow. The replacement I left hanging so it couldn't collect
water again, but during the summer my dad forgot and left the blower
on too long and blew the fuse (he was borrowing the car then). He
wrapped a bare piece of wire around the fuse to bypass it, but that
gives no protection against overheating and starting a fire.

Not necessarily. In the case of the Saab design, the resistors are
cooled by air movement through the blower assembly and in slower
settings there is insufficient airflow in the short space of time it
takes the thermal fuse to overheat. Starting the fan on full and then
turning it down to the desired setting allows positive airflow to be
established before the resistors are used.

i replace them on a regular basis with the fans not being a issue
