Thanks Peter. I'm trying to add r134 with UV dye so that I can find any leak present. I hope no water is in the system. Compressor seems to be fine.

You have a frozen evaporator from low freon, that's why the pressure is so low on the low side (expansion valve is completely closed). You may also have water freezing out at the expansion valve, blocking it. More to the point, you need to find and fix the leak -- if the freon is slowly leaking out, air and water are leaking in. Heat, water, oxygen, and R134a make hydrofluoric acid, which will very rapidly eat the compressor.
