One very easy way: turn on your A/C; it should kick the fan on regardless of the temperature. Found this out in the shop manual; it works on my '93 and is the only time I have EVER seen the electric fan turn on.

Bring a good battery or a portable jumpstarter and run your + and - wires from it to the fan. If the fan spins, it's good to go. It's how I did mine. You can also get em on ebay for about $60 new.

The fan should spin freely by hands with no noises. To properly test it you will need to hook the positive and negative wires to a battery, though.

mine may not have worked since i bought it and i just realized it.

lazy owners..

Studmifin-

Does your Jeep have two electric fans or one electric and one run by the belt?

If one is electric, turn on the A/C and see if both are spinning.
