If you are to that point, yes, it is toast. If you have had any failures in the system where metal has been present, you will need to replace the condenser. They are not serviceable, or flushable, you will need a new one. The AC on these trucks SUCKS. And check the high pressure sensor up front by the radiator CAC, that goes bad quite often. I had the part number posted on the old site... It is gone.
