You definitely do not have an operating compressor.
Whether it is the thermostat, the compressor, a relay, a bad connection or bad wiring has to be determined.
If you are handy, short the THERM connection at the A/C unit. That'll divide the problem in half.
If you are not handy, a trip to the dealer is in order.
