If you jump the system so that the compressor comes on, does the AC work then? I know you said that you had it recharged but it is impossible to charge the system if the compressor is not coming on. I know on my Volvo there is a pressure switch that keeps the compressor from coming on if there is not enough freon. You should try to find the wiring diagram for your car and see if there is a pressure switch in the system and then jump that to see if the compressor comes on. If it does, then you need more freon or a new pressure switch.
