Air Conditioning problem

Low side shrader valve for low side port was replaced after 2 week AC is blowing hot air again yet no leaks found.

If there is a leak, and there is dye in the system, look for something in the evaporator or expansion valve to be leaky. I am assuming the exposed parts of the system are leak free, so that leaves the parts that are not exposed, that makes sense doesn't it?
