inside the ceiling panel for my AC there's a schematic that shows what all the connections are. Just pull the ones for the compressor and condenser fan off the thermostat and jumper them appropriately with stiff pieces of wire.
as I recall, it was three wires. common power in, fan high and compressor. jumper those three and she'll run till she burns out!
be wary of ice-up on the cooling fins, as the temp drops, humidity is going to increase as it's hard to extract water from cold air without freezing it.
