I have a 2005 ford focus the AC does not work?

I have a 2005 ford focus the AC does not work. Sometimes the light will come on but it is not blowing cold air it just feels like a fan but most of the time the light won't even come on. Does anyone know how to fix this?

Hi you need to get it re-gassed i would have thought by now. So go see a ford dealer to get it done.
