Remove the connector from the pressure switch, which is usually located on the receiver-dryer unit which should be near your low pressure charging nipple. Pull the connector, jump the terminals and see if your a c compressor clutch locks up, if it does then you can attempt to recharge it, if your system is too low, the pressure switch will not allow the a c to start up, thus spareing the compressor damage. Possibly your system may have a leak.
