2000 Cherokee fan motor only works on high?

I have a 2000 Cherokee and over the winter the fan motor stopped
working on settings 1, 2 and 3 but works on 4. The winters are cold up
where I live so this was not a big problem, but I would be curious to
see if anyone has seen this problem.

Thanks,

Greg

Yes, it is a fairly common failure of the resistor pack. The pack is
locate at the bottom of the heater box in the passenger footwell under a
plastic cover. Remove the cover with one or maybe two bolts and you can
change the pack.

If this resistor goes again it means the fan motor is worn out. When
they get old they can draw too many amps and overheat things.

I hear there is a thermal fuse on some of the resistor packs that goes.
If you are handy with electronics and a soldering station, you might
want to just change out the one component part if that is all that has
popped. I would try this but I have lots of time on my hands.

Do not solder a thermal fuse - you will blow it immediately with the
heat. They are always crimped, and usually easy to find and change
(Try Tandy/radio shack type places).
