It is a two speed system that utilizes two relays.

Just to add to it myself, CJ MEDEVAC's link should be the cooling fan module, but they call it a relay also and is behind the right side headlight. The bumper skin would need to come off to replace it. Attached image of what it looks like. Here is a link to do it without removing the bumper skin.

Hope this helps. Is that behind the passenger side light

This one is not in the relay box. This truck uses a solid state relay and it's hidden very well.
The Pulse Width Modulated (PWM) cooling fan relay is located below the right headlamp behind the bumper fascia.

How do you locate and remove the radiator fan control relay circuit and do you have a diagram/photo of this process? Have
just purchased a Haynes Repair Manual today, but it doesn't show or tell me anything about this circuit except code #P1491, which is this relay. What a waste of time and money today, HA-HA, but will be helpful in the future, I hope. Have also purchased the relay circuit and I'm ready for home repair. Would greatly appreciate any info. Please HELP Thanks

Hello and thanks for using 2CarPros!

Please refrain from flooding our forum, we see your first post fine it just takes time for us to get to everyone.

Your vehicle's cooling fan relay is located behind the front bumper fascia, below the passenger headlamp. I have posted a diagram below.

Find the power distribution center under the hood and your owners manual will have a diagram for it
if you don't have owner's manual let me know. Failure can also be a temp sensor problem.

The relay is not in the box. According to Haynes (page 3-6) the relay is under the car but I can not see it from the bottom or from the top.I would like to know just where it is and how to get to it.
Thanks,
Frank

Which type do you have? Some models have a plug-in relay in the under-hood fuse box. You just yank the old one out and stuff the new one in. Those don't fail very often.

Some models use an electronic relay. It looks like the one in the photo below from www. Rockauto. Com I don't know where they live on Jeeps but on other similar vehicles they are halfway down on the driver's side of the radiator, bolted to the sheet metal beside the radiator.
