Mines packed up as well. I thought the pipe came off too but there was no water ingress anywhere in the boot or anywhere else. I took the washer jet out and it was simpley blocked with crap. I cleaned it out and it now works like new.
i poured some hot water with washing up liquid into the washer resevoir, took about a minute for it to cleap the whole thing through, never worked before in the 3 months i owned the car, fresh out of the kettle.
mine packed in too but it was the pipe that was off it. But now I have a different problem the wiper will go constantly when switched on and will stop in what ever position its stopped in. It will now return to the position it started in, how dow I fix this or is it normal
