Why does my AC only blow cold air when the car is moving?
Another reason why the air conditioner works only when your car is moving may be low freon levels. If your air conditioning system freon levels are below what is needed, your car ac will not cool properly. As a result, it only cools when your car is moving as the car is then capable of pumping the freon with ease.
