I think your problem is that the 03 system is computer controlled and the cycling is controlled by the 03 engine computer which is gone. A 12 valve system uses a low pressure cycling switch whichs works only by the pressure in the system to turn the compressor on and off. You will need to incorporate a cycling switch used on a 94-97 12valve to make the compressor cycle.
