TOM......I bought and installed a new compressor from Prevost. After 8 cans of 12oz freeon, I had a leak on the back side of the compressor from the overflow pressure release port. I has a restriction in the evaporator located on the driver side under the power steering resevoir. Replaced the evaporator , converted from R-12 to 134a. It has cooled very well for the past year.
