Air conditioners make it cold inside the unit at a condensation surface, collecting the water from the humid air there.
But that’s not how you defog a window, you heat the window until the air in contact with it can hold more water and so the water evaporates faster due to both water and air temperature. THEN this air can be pulled back into the AC to deposit it there with condensation.
Window / mirror defog doesn’t work like regular dehumidification that way. Especially not in cars / bathrooms where you might be having a too high stream of humid air coming in, then you focus on one surface (and since the windshield don’t tend to have heating wires, it uses the AC hot air)
