How does the cooling system work on a Jeep Cherokee?
When coolant temperature is below 190*F (88*C) the switch is open preventing the relay from being grounded and the cooling fan from being energized. When the air-conditioning is used the engine ECU grounds the A/C relay coil allowing current to flow through it.
How does the cooling fan work on a Jeep Grand Cherokee?
The cooling fan in a Jeep Grand Cherokee keeps engine temperatures at the correct level by kicking on during times when the engine reaches higher-than-average temperatures. Without it, the engine can reach dangerous temperatures and damage engine components.
Why is my Jeep radiator not turning on?
The fan will turn on after the temperature reaches about half. Usually comes on when the car is standing still due to the small amount of air circulating through the radiator. Too many mods to list… No the AC will turn the radiator fan on to pull air across the condensor.

Can a hydraulic radiator fan overheat after standing still?
But first check the hydraulic cooling fan control fuse # 16 in the PDC. When that one is blown, the fan just keeps at the 500 rpm speed and you will indeed overheat after standing still for a while. If your cooling fan is taking off then thats not your problem…
