This is an odd ball question, just something I was wondering about. At idle, when my car is at normal operating temp, my A/C compressorkicks on fora few seconds then goes off. Is this because the thermostat opened and the engine needed to be cooled slighty. I am asking because I have never heard or seen my fan ever run. I know at highway speeds, the air flow through the radiator will help cool the enigne, but at idle, the compressor kicks in. Just wondering if this is normal on all stangs or not. Noting is wrong with my car and it has done it for as long as I can remember.
