A/C problems

     Hi all,
     
     I'm having a problem with my air conditioner.  Its finally cool enough 
     here in South Florida for fresh air, and suddenly my air conditioner 
     won't shut off.  With the a/c switch in the off position (the switch 
     depresses, the light goes out), the a/c stays on.  Also, the blower 
     fan will not shut off (when in the off position, it blows as if it 
     were on the lowest position).
     
     Any suggestions for determining the culprit?
     
     Thanks,
     Heidi
