your a/c compressor may be bad, or there is no flow in the system 2ry to a blocked condensor, or reciever-dryer.
try to start the car, attach gauge, short the low pressure switch and put a/c on -your compressor should go on. Now pull accelerator cable to speed the motor - if compressor is working, the pressure should drop. If the pressure does not go down -possibly bad compressor. if you get "frrrr" noise w/ discharge from the compressor - it's a safety valve future that prevents system from overcharge - you got too much freon.
