Although I haven't looked at my 08 Caravan, in the past the spray nozzle was mounted in the rectangular plastic housing that sits on the hood. The actual nozzle was a small metal ball sitting in the plastic housing. The nozzle ball swivels in the plastic housing. Find a large safety pin, open it, and stick the sharp end into the ball end and swivel it up. Do so carefully so the end of the pin does not break off in the nozzle. If there is no swivel ball, perhaps it adjusts by moving the plastic hose under the hood.
