How does the washer motor on Fiat Punto decide to send water front or rear jets?

There is no washer motor on a Fiat Punto that decides to send water to front or rear jets instead. The decision on whether to activate the front or the rear jets is made by the driver via a switch on the dashboard or a stalk on the steering column, depending on the model of Fiat Punto. Once activated, water is sent to the respective nozzles located on the bonnet or tailgate.
