A washer fluid level indication system of a vehicle determines a present volume of washer fluid present within a washer fluid reservoir. A flowrate module is configured to determine a volume of washer fluid dispensed based on a measured voltage applied to a washer fluid pump and a predetermined volumetric flowrate of dispensing washer fluid calibrated based on a predetermined voltage. The flowrate module is configured to subtract the volume of washer fluid dispensed from the present volume. A level module is configured to determine a present level of washer fluid within the washer fluid reservoir based on the present volume and a predetermined maximum volume of the washer fluid reservoir. A display control module is configured to display the present level of washer fluid within the washer fluid reservoir using a washer level indicator.

Washer fluid level display control systems and methods

A spray nozzle system includes a housing having an upper cap, a neck portion for helping to support the housing adjacent a component, and at least one fluid flow line for supplying a fluid to an interior area of the housing. A plurality of spray nozzles may be included which are housed in the housing and in communication with the at least one fluid line for distributing the fluid over a circumferential surface of the component.
