I need help with the AC. I rinsed condenser changed hi pressure hose with filter and receiver dryer rinsed compressor and added oil. Vaccum pumped to 35 hg and held for 30 mins. I went to charge and it seemed to go high like 55 per the gauge on the can right away I’d bleed out some pressure for the high side but it was warm to ambient temp. Same deal on low side and neither the line and can ever got cold. At one point compressor would cycle on and off but at pretty high pressure. Adjusting screw at the receiver pressure switch didn’t seem to help. Switched out another used switch. No help. Jumped switch with wire and got Compressor to cycle. Now show 45 hrs but air off the valve is warm. ???? What am I missing. Something blocked? New receiver pressure switch??
