Thank You Larry... I was told that the compressor is shot and given a horrific price to replace it. I am a chef and always play with my food and love working on my car, so what the heck I will get the parts and do the work. I do not want to be a penny thrift and a dollar foolish so I am replacing the AC components that commonly fail. I am really uneasy about what are the do"s and don'ts when working on the AC system. I have had the system depressurized, now do I coat the fittings with refrgeration oil ? Should the drier will be the last thing I connect before taking to be flushed and recharged with R134 ?
