Is there an option to add a sprayer to the rear wiper arm? When I activate the rear sprayer I can hear it (pump) but noticed that the tube is terminated on the arm. Took off the "plug" but still didn't pump any fluid. Why have everything there just to terminate it where you need it? Live on a dusty road and would be nice to wash it once in a while
