Few days after adding a can of freon to the ac service port, a hum and wine noises started coming from my air compressor. But goes away with higher rpms, and the air works fine nownits even cold, but is it getting ready to quit on me? If so is there anything I can do to prevent it from a total loss? Also, when it goes completely out, will it interfere with the rest of the engine components on the serpentine belt? And other problems with my car, but not sure if its related, the interior dash lights flashing on and off, started about a week before the compressor noises. I checked all my fuses, they r good, although some seem loose. I havent had much time to investigate it, since the latter prob started.

Do you
have the same problem?

You should never just arbitrarily add refrigerant to a system. It is engineered to run on a very specific amount and too little or too much can do serious damage. I would take it to an AC specialist and let him evacuate and recharge it with the proper amount and if the noise is still there he can tell you what it is. AC repairs are not a DIY type job.
