My 2000 Ram AC stopped blowing cold overnight it seems. One day ice cold the next hotter then well you know. I checked the low side and it's about 45 with the compressor running. The high side I haven't checked (don't have the gauge) however the line is cold. I was told that the evaporator, accumlator and orfice was all bad, somehow I fine that not to be true. maybe one or the other but all of them.

Anyway I was wondering how to Evac the system at home?
Has anyone changed the Evaporator and any tips?
Could it be clugged and just need to be blown out? if so how to do that??

Thanks,
