A method comprises detecting an object 170a exterior to a vehicle 100 and actuating a fluid dispenser device 240 based on an opacity of a window 215 and a location of the detected object (a more specific embodiment is shown in figures 4A and 4B). The detected object may be a pedestrian and the actuation may occur upon determining the opacity exceeds a first threshold and if the location of the object is outside a splash zone of the fluid dispenser. The splash zone may be adjusted based upon wind intensity and direction and the actuation of the fluid dispenser may operate according to the adjusted splash zone. The method may incorporate a delay time based upon the object location, vehicle speed and vehicle movement direction and actuating the dispenser after the delay has ended. Alternatively, the fluid dispenser may actuate without waiting for the determined delay time to end if the opacity exceeds a second threshold greater than the first threshold.
