Why does my AC only work when the 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 not work at idle?
When the car is a idle it is most likely not moving. The only air moving through the condenser coil is being moved by the engine fan. That is much less air flow than when the car is moving at say 40 MPH. Less air flow means less cooling for the hot refrigerant gas which means, you guessed it, less capacity.

Why does my AC only work when I Am driving?
Your AC only working while you are driving might have to do with a low refrigerant level, or it may be an indication that your electric fans are not turning on. Try checking the fuse and relays for your fans to make sure they are turning on when you turn the AC on. My AC was working fine til today I just started my car an the AC just shut off.
