The compressor is trashed and locked up. Was gonna pull the system down (have access to a A/C machine) and remove the compressor replace it, along with a new dryer and oriface tube. Question is what do I use to flush the system out? Or do I even need to worry about it with replacing the basic's. I'm guessing theres gonna be metal flakes thruout the system. BTW 95 Chevy wagon 100k miles dont look like anything has been messed with. I had it recharged earlier this year was less than a lb low been working great till today.
