In my case the bearing went bad and "froze" making a loud noise and making the fan belt smoke. If it does not make a noise, check the voltmeter on your dash - failure to charge could indicate the alternator is not working, but I think others things are more likely . It should be easy for a mechanic to test to see if the alternator is charging.
