what is the last 7 digits of the vin?
this vehicle has only one fluid reservoir that feeds all outlets for both the windscreen and headlamps so this system is fully connected.
if you cannot get any fluid to spray for the windshield or add much, then you may have a blockage or air pocket in the system, or a failed wash pump for the windscreen (the windscreen and head lamp washers share a reservoir but have their own pumps). you could try checking fuses but that isn't a likely cause - more likely the wash pump is bad or there is some other blockage/restriction/air.
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
