Why does the AC blow cold air when the car is moving?
My car has an automatic transmission. When the car is moving, versus stopped, there is more air flow over the condenser (the heat exchanger in front of the radiator) and that airflow is essential to system operation. To maintain airflow when the car is in stop and go traffic, or is completely stopped, condenser fans will come on automatically.
Why does the AC blow warm at idle?
Since the AC compressor is driven by the engine, it doesn’t pump as much refrigerant when you’re at a stop or driving slowly. If the system is low on refrigerant, it will show up as AC blows warm at idle and blows colder when the engine is running at higher RPMs. Get your system refrigerant level checked.
