BK-
I see a new fan in your future. If the fan and light are controlled by a single switch, then your fan is dead.
I am not trying to be offensive here. I say that because sometimes I am. But check the switches and stuff on the fan. The rotational control might be in a neutral position. The on-off switch for the fan could be broken.
If you or a friend have a volt-ohm meter, you could quickly figure out what the problem is.
As they say in LA- Watts happenin'
