I have a 2012 CRV. I live in a warm climate so I know that this is not due to any freezing. There is wiper fluid in the car. Are the front and rear wiper fluid systems connected and what might cause this to happen?
I have seen it where the hose has come loose and disconnected and not spray on a 4Runner. Exactly what your describing. Trace the line from the reservoir under the hood and look for a connection in the line that has come disconnected.
