I got the compressor off, after disassembling most of the front end, and I can get to the filter drier to change it. So I think what I will do is Pressurize can A/C flush the lines and the condenser. Then try flushing the evaporator through the expansion valve, just on the inside, behind the bulkhead. If that flushes ok, I think I can get away without digging into that valve under the dash....:thumbsup:
