Compressor is toast-- the wobble plate is trashed- can't wobble internally-- the V-5s do that when constantly run on low refrigerant charge.

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
