find the fan relay.

Do you have a good Chilton or Haynes Manual for your Jeep?

If not get one.

Welcome to the Z. What year jeep?


Could be a bad fan relay, you can test by swapping in a different relay or using a jumper wire to activate the fan manually.

turn on the AC if you have it, this turns the fan on instantly if the fan runs its probably your temp. sensor located on the thermostat housing if not its most likely the fuse or the fan relay located in the fuse box under the hood behind the battery there's a relay and fuse directory under the cover
