If you have the Calsonic Kansei compressor than you have the variable displacement compressor. Most likely the solenoid that control the the variable diplacement of the compressor is not working properly so the compressor never get to the point that it is actually pumping refrigerant through the system at the very beginning. Once the engine had turned the compressor after awhile the compressor kicks in and enough refrigernt is flowing that the system is working. Never had any trouble with my fix displacement Denso compressor all the years that I own my X.
