No it should not run constantly. One of the switches used to turn the fan on is broken, or stuck in the open/closed position. First thing, I would unplug the high side sensor on your AC system. That sensor goes the most because it comes into contact with refrigerant. It doesn't matter if you are using the AC (say if its winter), but if the switch is broken, it may think the pressure in the AC system is to high, there fore it will turn the cooling fan on to drop the temperature.
I wouldn't worry about wiring problems like opens in the circuit (broken wires), because then the fan wouldn't run at all.
If unplugging (maybe even jumping) the AC high side pressure switch, try other sensors that control fan operation such as, coolant temperature.
Good luck! __________________________________________________________________ I 100% agree with everything the first poster wrote. But if your on A budget. You can make A decision on what you want to do. That is not the design of the car, but, it will not hurt it at all. I definitely would not spend the money to get if stopped. ,,,,,,,,,,,,,,,,,,,,, If it stops running get it fixed. The fan motor will not burn up because it is running. but, It could already be worn and go out, Just make sure it keeps running and if it stops get the car fixed.
