Claim 8:
9. A method for sustaining a washer fluid system for a vehicle, comprising:
providing a washer fluid tank adapted to contain a volume of washer fluid;
delivering condensed liquid water from an HVAC system of the vehicle to the washer fluid tank via a conduit adapted to fluidly couple the HVAC system to the washer fluid tank;
providing a fluid reservoir disposed adjacent and fluidly coupled via a reservoir conduit to the washer fluid tank and adapted to selectively deliver a fluid from the fluid reservoir to the volume of washer fluid contained in the washer fluid tank;
providing a washer fluid pump fluidly coupled to the washer fluid tank and adapted to deliver washer fluid from the washer fluid tank to one or more nozzles disposed in washer fluid spray locations about the vehicle; and
providing a fluid injector disposed between the washer fluid pump and the one or more nozzles, the fluid injector adapted to inject a fluid contained therein into a nozzle conduit to mix the fluid from the fluid injector with the washer fluid outgoing to the one or more nozzles,
wherein the conduit comprises a filter adapted to prevent debris in the condensed liquid water from passing from the HVAC system to the washer fluid tank and an overflow outlet adapted to prevent the condensed liquid water from backing up into the HVAC system; and
wherein the washer fluid tank comprises a washer fluid level sensor operable for determining a level of the volume of washer fluid contained in the washer fluid tank and triggering the HVAC system to perform a water generation cycle.
