Auxilary/electric fan problems 4.0L

2001 Cherokee with 4.0L. It has a belt driven fan and a secondary electric fan.
Does this electric fan only come on with AC on? Someone has unplugged the fan and hooked it up to the AC clutch power and a ground so the fan now by passes the relay and whatever else and switches on when the AC cycles the clutch. I hooked the fan up right and now I cant get it to work.

The fan motor is good. The relay and fuse is good.

Does fan come on with AC as soon as you turn AC on? And does fan come on with AC off if coolant temp reaches a certain degree?

Anyone now why this fan is not being switched on?

There was a code that came up for the fan after I hooked it up right. It was a Aux fan Ckt problem code (open or short)

I know you Jeep guys know your Jeeps so I am hoping for some good input. I had a 98 Cherokee that I wish I would have never sold. I just got my parents to buy a 2001. And truthfully I am a Chevy guy.



Also when AC is on should the AC compressor clutch run in short cycles or should it stay on continously? Or does it depend on outside temp?
