When the car is idling, the ac stops altogether. When the car is in motion, it sometimes works and sometimes does not. When it does work, it does run at full capacity and will sometimes even blow hot air even though the ac is turned on. It is hit or miss when turning the vent settings as it doesn't always redirect the air flow. Also, it is hit or miss for the ac to turn off when switched to the off position (hot or cold air may continue to blow).
