Before I had problem with the a/c compressor. My car a/c system automatically on and off whether the fan blower setting is at #4 or #3 and thermostat setting whether from 70% to 100% at engine idle speed. And from those settings, when driving and accelerates the engine, it auto cuts off the a/c compressor. That is why I am wondering if they charge enough freon or not.
