Blocked or Broken Condenser If the condenser has gone bad, it will not be able to process the freon and produce cool air. 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.
Why does AC only work when car is moving?
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. Other possibilities are that the compressor clutch is not cycling as intended or that the condenser might be blocked or dirty.
Why does my AC stop blowing cold when idle?
Most likely problem is with fan system not operating properly to move air through condenser while stopped or moving slow. Dirty cooling fins, faulty fan clutch or malfunctioning sensor could cause this. Another possibility is charge in system is low affecting its efficiency.
Why does my AC get warm at idle?
Your AC system is low on refrigerant. 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.
Why does my AC only get cold when Im driving?
Most systems ensure that the radiator fans are set to run at low speed all the time if the air cooling system is engaged. This draws air across the condenser coil and helps it to lose heat. If you only get air cooling when in motion, then those fans are perhaps not working as they should.

Most likely the cooling fan for the condenser is not turning on allowing the high side of the A/C system to get to hot. This reduces the cooling capacity of your system. The cause can be the fan motor, a cycling switch, or a temperature switch depending on the design of the system in your car.
