If your saying you jumped the compressor and the compressor came on that means that the system is probably low on freon. It has a cut-out switch that won't let the compressor come on becasue the oil is mixed in with the freon, so no freon means no oil. You most likely have a leak at the evaporator if you haven't had it fixed yet. Do a search, I'm sure it's been covered before. Also, ALL CAPITALS usually designates yelling over the internet, please turn off the caps lock.
Thanks David

The compressor is directly controlled by the base module based on an input from the PBC.
