Please help with ac so I need some opinion on my cars r134a ac. So I had a schrader valve leak so I swapped them out. I pulled a 500micron vacuum on it then when I went to go recharge it it barely sucked anything in. 4oz to be exact. So I used another can to squirt some in and I charged it up to 21oz(cars specs) But my pressures are all crazy. 45/19. 45 suction side 19 high side. I have the field piece sman gauges. Why would my pressures be like that. It’s blowing cold but I don’t under stand that. If mycompressor wasn’t working it wouldn’tbe cold. Can anybody chime in?

If it's cold I would say gauges are off. A static charge is about 100psi. Is it possible that gauges are calibrated for different scale other than psi? High side will be over 100psi working
