Need expert advice to Interpret AC pressures

[Canadmin]

I have a 99 sonoma 4.3. I am not getting cold air from my AC. I replaced the condenser a while back then refilled the system and it worked but the system was still leaking. I've just replaced the O rings in the lines and now there are no leaks. Pressure readings when engine is off = Low side 50 psi. High side 50 psi. With engine running - Low side cycles between 30 and 50 psi. High side stays at about 50 psi. I don't see anything in the sight glass. Compressor clutch is working. I think the compressor needs rebuilding or replacing. Can someone out there verify or clarify this for me. Thanks in advance.

   It sounds as you covered the basics. Have you checked all the connections with dish soap when it is running? Any bubbles would indicate leaks and possible cracks in the lines. If all that is good, the I reccomend you buy new condenser and swap out.
