I don't have any experience of Jeep resistor packs, but others (like
Saab) have three large resistors (that rarely go) and a thermal fuse
(that often goes). The thermal fuse is an inexpensive item and a
replacement can be crimped on. Available from Tandy/Radio Shack.
The Saab had the problem since the resistor pack was located in the
airstream for cooling, but in position one there wasn't positive
airflow before the pack got too hot. After changing a thermal fuse in
one I found that by switching the fan to max and then to the desired
speed the thermal fuse didn't blow again.
I don't know how or if this applies to the Jeep.

In the Saab design, since each speed has it's own resistor (apart from
full speed) it's unusual for the resistors to all go. There is
usually a thermal link that blows and can be replaced. Note: crimp,
not soldered.

Re: 98 XJ Heater Fan Control Operates on "4" (High) Only
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.
