I would first recommend vacuuming the system down then try charging it, check the plug that plugs into the front of the clutch pull it out and use a test light on it to make sure you are getting power to the clutch, then proceed to re-charge the system and check your results, you can try replacing and jumping relays which are located on the firewall of the engine but that is a last resort, see what you come up with the test light at the compressor clutch
