I have an Audi A4 FSi Avant 2003. About a month ago the rear washer stopped working but I automatically assumed it was the water level running low. The wiper continued to work fine until about a week or so ago without the water. Now the wiper has stopped working and is stuck half way which is very distracting. I was going to check the fuse this evening but when I switched on the ignition, the wiper moved to another position (which is better than the last at least). Seeing that it moved briefly this evening, I assume it cannot be the fuse. I filled up the water reservoir to the top and the water is still not coming out. Everything seems to make all the usual noises when I turn the rear washer on, but still no water. I can also here the clicking in the back which I assume is the relay. Any ideas much appreciated. HH
