My guess is that it's either too tight entrance conductors (wind vibration similar to guitar strings being plucked) or the conductor bracket has loosened over time.

In either case, YOU MUST CALL a professional to correct the problem. Theses conductors are not protected by any over current protection and are being fed at nearly 300 volts, ac, p-p. (240 volts RMS but your body will feel the full 295 volts). Any contact will result in *****.

Try talking to your local utility to start.

If your compressor is "locked up" there is no way to mechanically free it. The compressor will have to be replaced, a vacuum pulled on the system and new refrigerant put in the system. This is beyond the scope of the average do-it-yourselfer. I recommend taking it to a shop that does AC repair work.

Well, with limited information about what AC you are trying to charge its hard to say. However,If you are working on a vehicle most car manufacturers have the information available under the hood. In most cases there is a lable on the radiator core support stating how much 134a and PAG oil type you need for the application.

It will look something like this.

Check your vacuum system where it feeds into your AC control system. Likelyhood is you have a crack in some component or a loose hose. Laurin
