Ok then check your actuators in your hvac unit, they may sticking, losing vacuum or electical if they are that. I'll send a generic pic along. Also your pressure switch on teh evaporator may be bad, but you should still have the pressure checked, it could be a blockage in the hi pressure line where the filter is. When you jumped the low pressure switch did it kick the clutch on? If not it may be another problem like the high pressure switch on the compressor is kocking it off. It really needs a set of gauges on it to see what 's happening.
