could be a number of simple problems. one is your temperature sensor...if it fails it wont turn on your coolant fans. 2nd is your coolant level might be low...if its low then the hot coolant wont be able to "come in contact" with the coolant temp sensor thus result in over heating...i doubt its fan failure as it is highly unlikely that BOTH fans would fail at the same time. however it is possible. lastly is electrical to both fans has failed...put a tester into the connector (not into the fan) and start the car....let it warm up...as it get too hot the voltage should suddenly be there...if not...then the fans are not getting power and you have electrical issues. may have to trace the wires and find out if they got damaged by a belt...the fan or other moving part... i hope this helps you out

As long as the fan eventually shuts off this isn't a problem,the fan will continue to run for a bit after the car is turned off,once it reaches a set temprature it will turn off.

There is no machine for this,however a VERY skilled auto electric shop might be able to help.They really have to have a Gift with car wiring to fix your problem,it can be FIXED,find the right shop in your area.I will try and think this through to help you,this is what I used to do,It's not a book problem it is experience that will fix your car. I do have a question? How does your car run without the AC on?

That is nothing to worry about the fan remains running after the vehicle shuts off in order for the engine to cool down. Once the motor cools down sensors trigger the fan to shut it off.

SOURCE: Radiator Fan Stays On
A simple test would involve disconnecting the fan switch while the fan is on. If the fan then stops the switch has failed. If the fan continues to run remove the relay , if the fan then stops the relay has failed.
Various inputs/outputs at the relay should be confirmed to be 100% certain something strange isn't going on.
Above all be careful of the fan itself , if it's running obviously but if it's not it could start during repair
