Thanks for the link to the AC tutorial. Tutorial said that as my compressor is not cycling (because the EC light won't turn off), I cannot get accurate pressure readings. If I can get the EC light to turn off, then the compressor should cycle. My research shows a faulty AC sensor could be the culprit, and not allowing the EC switch to work. How do I get the compressor to cycle? Is there a way to by-pass the EC switch? Or??
