![]() ![]() Issues of this nature that are caused by foreign objects can have a number of adverse effects on the system and should be handled by experts with proper inspection. Obstructions in the condenser or breakage of the cooling fans are among the two big problems caused by the debris. A broken condenser might malfunction when there is a cut back in power as when the car is idling or running the AC purely on the battery.Ĭontaminant or any kind of debris entering into the system is a common problem for car ACs as they are located at the front of the vehicle. If the condenser has gone bad, it will not be able to process the freon and produce cool air. It works to turn the freon gases back into liquid form. The condenser is primarily responsible for ensuring cool air from the AC vents. If the car is moving, the air conditioning system will not require a secondary cooler. Your car AC relies heavily on the motor fans to circulate the flow of freon when the car is at rest. If your car ac pauses the flow of air when idling but turns back on when you begin to move, the first place you should turn your eyes is the motor fans. This is another reason for a car AC not blowing cold when idling. A standstill engine combined with a low amount of freon will render the compressor unable to circulate enough refrigerant both due to low power and low freon. The compressor circulates freon in the AC system to cool the cabin and it is able to do it best when the vehicle is in motion due to the amount of power it is able to draw from the engine. You may also notice a similar drop in cooling from a leak when idling. A significant drop in the refrigerant levels is usually caused by a leak and it can be actually noticed assessing a sharp decline in the cooling performance. ![]()
