When the system is in the defrost position the a/c compressor comes on and the air is drawn in and sent through the a/c evaporator to remove moisture from the air before it is sent through the heater core.

Why do my car windows frost inside?
A Frost accumulates on the inside of the windows when water vapor inside the car condenses and freezes. When a car is parked overnight or for an extended time when it’s cold, the water vapor condenses on the glass, which cools very quickly. Then, as the car cools further, the condensation freezes.
Should AC be on for defrost in car?
The warm air from the defroster helps evaporate the moisture near the windshield, but it’s only a temporary fix. If you want to stop the fog from forming, experts recommend using cool air to lower the temperature on the inside of the glass.
Does AC compressor affect heat in car?
The compressor constricts the refrigerant, and it begins to lose heat as it passes through the condenser. All the while, the refrigerant is becoming depressurized and getting cooler. Finally, refrigerant makes its way to your evaporator, which removes any remaining moisture and cools the temperature even further.
