I have a 2019 Grandland X. The front and rear windscreen washers have stopped working. Both fuses are OK and when I've removed the pump and tested it with 12v it works OK in both directions. I also have 12v present at the pump connector when the stalk is pressed for front and back. I've also tried a new pump. When it's all reassembled it doesn't work. Has anyone had the same issue or an idea what it could be ?
