Cooling fan
 

Got a 2010 Hyundai Tucson I have a issue with my cooling fan it started when it didn’t come on at all I changed out the hi pressure temperature sensor and fan came on and stayed on until I turned car off so I changed out the relays that didn’t do anything so today I changed the water temperature sensor and same thing is it a chance it’s the fan control module or just replace the whole unit? Any suggestions

Many times the way the system is designed to work is misunderstood.
Many vehicles today are designed to have the fan run anytime there is loss of control circuit function. That means, if it goes south for any reason an overheat condition will be prevented, but the fan runs all the time.
The circuit needs to be checked out to determine where the function that holds the fan off is lost.
