Probably hotwired because the compressor kept cutting out. There are many root causes behind the dreaded compressor drop out syndrome. Fortunately they are usually not too difficult nor expensive to address once one actually understands how the system works. Sixto's search recommendation is a good one. I might add "compressor clutch gap" and "rpm sensor" in addition.
Strongly suggest you un-hotwire the compressor. In addition to freezing up the evaporator, if the compressor locks up it will take the serpentine belt with it. No belt, no water pump nor alternator. Doesn't seem worth taking the chance.
