Its probably the reason behind it is a bad power control module on the blower motor. If you mean the engine cooling fan, just because your jeep is controlled by computer and its depends on the internal engine temperature the reason why your fan may turn on and off.
not the cooling fan the blower moter that heats the car keeps runing after car is turned off on full blast when car is on can not turn down add a comment
