What should the pressure be on my a / C compressor?

Why is my air conditioner compressor cycling on and off?

The air conditioner compressor was rapidly cycling on and off. I turned the A/C off and stopped putting R-134a into it becuase the compressor cycling was almost causing the car to die from the load it was putting on the engine. Onto Google I went.

Why does my car AC blow cold air then blow warm air?

But that cold air turns warm fairly soon after because the high side pressures build to the point that the high pressure switch shuts off the compressor clutch. Once pressures equalize, the high pressure switch allows the compressor to start up again. The cycle repeats over and over, providing a short period of cold air, followed by warm air.
