Air Conditioning problem

This year my a/c did not seem to be cooling very well. It would cycle on and off too frequently. I figured it was low of freon so I purchased a gauge and can of R134. When I installed the freon the gauge was reading 0 when the clutch was not engaged. When the clutch engaged it jumped to 20. The instructions told me to charge it to 45-65. The whole can was installed and the pressure read was 45. The air was cold and the compressor did not seem to cycle much. This last for about 2 days. It then began to blow warm air again and started to cycle too often again. I thought maybe it was a leak so I bought a can of dye and hooked up the guages. This time, with the guages hooked up and the clutch engaged the pressure shot up to about 100 and then about 75 when the clutch was not engaged. I began to think I overcharged it so I let some freon out and then the air began to blow cold again. This lasted about a day and now the air is hot again. Is this typical of a malfunctioning a/c compressor? Thanks, Tommy

no thats not typical of a malfunctioning a/c compressor. I do believe there is a leak in your system but i also believe your pressure switch may be malfuncioning though
