Yeaaaap. Mine is cycling about 3 times a minute.It is completely normal for the system to cycle at idle. By frequently I mean if the A/C clutch cycles on and off several times a minute. At idle and about 80-90 degrees outside with less than 20% relative humidity, a properly charged A/C system should have the clutch engaged for about 1.5 minutes and then off for 5-15 seconds, just for reference. The functioning of the system changes with temperature and humidity.
