Why does my AC motor heat up when there is no load?
if rotor moves freely , then you could check the resistance of the windings , possibly a winding short circuit, that would explain the motor heating heavily with no load. I would put my bet on faulty winding isolation personally , fropm what i have read. Almost certainly an insulation breakdown resulting in a shorted turn.
What happens if the air conditioner does not work?

Any problems with the pump from erosion, leaks or anything else can cause your vehicle to overheat. An overheating vehicle is a sign that needs immediate attention.
How can you tell if your car has a bad air conditioner?
Another way to test the fan is to turn on the air conditioning. The cooling fan is activated in most—but not all—cars when you turn the AC to either a medium or high speed.
