The front windshield wipers on my '94 XJ have not been spraying. I recently replaced the reservoir and the pumps. The wiper blades run, but I cannot get the sprayer to work, so I am assuming its not the motor. Or is the motor specifically for the spray function? When I hooked up the front sprayer to the back electrical, it worked, so I am assuming it is something electrical. Any leads on what to check next? Appreciate any help!
