The window washers on my golf gti mk 7.5 have stopped working. I can't hear the motor turning, there is no individual fuse and I have already taken the outlets off to clear them. Still nout. There is no warning message on my dash, does anyone have any advice on what the problem may be? The liquid is not frozen, they have been faulty for a few weeks before the colder weather came to Scotland. Any advice is appreciated.
