You can tell if the fuse is blown because the fan will not even attempt to turn or make any noise. If you ‘fling’ the blades with your hand, still nothing (sometimes that starts them when they are sticking). But if the fan makes a noise like it is trying to start then it isnt the fuse.

An electric fan SHOULD NOT run all the time. The fan turning on is normal and a consequence of the hot coolant, not a cause. The coolant may not be moving due to a water pump problem, blockage in the radiator or hoses, or a stuck valve, i.e., the “thermostat” in the coolant line.
Q. Why is my radiator fan running all the time?
