Sometimes, there isn’t quite enough rain to keep the wipers on, but too much to turn them off. Enter the intermittent setting. It has the wipers perform one wipe cycle, then pause for a short time before the next wipe cycle, thus allowing enough moisture to build up before the blades wipe across the glass. The intermittent setting results in cleaner glass and less wear on the wiper blades during light rain, snow and mist conditions. On some vehicles, the wipers automatically switch into the intermittent mode when the vehicle stops.
