It's of the back side of a Cherokee dash, roughly the same year of
your YJ tub, The location should be the same at the end of a harness
below the whiskey chest. And of course the test sequence will be the
same.

Re: Thought it was a bad fan switch.....
 

It is inside the Jeep on mine.

What year is your CJ?

On mine it is dead center above the fresh air vent on the passenger side
and has a 3 pronged plug on it with one brown and two black wires.

The resistors themselves do look like heater elements or light bulb
filaments. They are just a coil of wire of different thickness'.

They heat up when the power is on low or two as they drop the power down
to the fan. That is why they are inside the heater box, they need air
flow or they will burn out.

I looked it up in the 4WD catalogue and they list the same 3-speed fan
switch for 1976 through 1986, dunno what they went to after that. On the
odd chance that AMC didn't change the heater design too much, the CJ
resistor pack (to set the fan speed) is screwed to the heater box just
above the vent outlet, above the passenger's right foot. The pack is a 1"
x 3" piece of particle board with three wires running into it. If the
connector has come loose you won't get lower fan speeds, and if the
nichrome coils (on the other side of the mounting board) are toast you
won't get lower speeds either.

Happy hunting.
