Yeah it is a new compressor, I am only getting 9.5 volts from the switch, therefore their is not enough volts to keep the clutch engaged, it will engage then kick out...

I would suspect a low charge or a bad cycling switch. The dash switch is just part of a circuit that tells the PCM you'd like some A/C, please. The clutch is run through a relay on the fender.

It is mounted near the h-block, there are 3 wires, if you connect the 2 outer wires on the plug it will bypass the cycling switch and the compressor will run constant.
