96 Ford Taurus AC fan won't turn on

I have a 96 ford taurus V6 with around 90k miles on it. When I shut off the engine the AC fan did not turn off (it kept running). I turned the engine on and then off again and the fans turned off. When I started the car up again I had no fans. I can tell that the AC is still working, but there is just no air in the car. I have checked fuses, but the manual the car came with doesn't really go over this problem. Any ideas?
