A/C Pipes are Hot!

Ok. The A/C blows cold at first then blows hot; not warm but hot. The length of "cold time" depends on the temperature outside. If it's around 75 degrees it will blow cold for a good 30 minutes. The A/C pipes will be frigid cold and have condensation. If it's 95 degrees out, I get 5-10 minutes of cold at best then it goes hot. At this point the pipes leading from the evaporator to the compressor are HOT as well. The A/C will continue to blow hot until I shut the car off for a few hours. Anybody know whats going on? By the way the system was checked for leaks; no leaks. The pressure on the low side port is right where it should be, 40-45 psi. I've heard this could be a blend door or venting problem. Any thoughts?

sounds like you have a plugged orifice tube it is located in the condenser and yo have to replace the condenser to fix it. i would first hook up both the high side and low side gauges and let it run. then when it starts to blow hot let me know what you readings are and i can help you out from there.
