Wiperes jammed!!
 

I have an Audi A6 1998 1.8T and have a few issues to resolve if any one can help please?
- The wipers are jammed. They jerk when I switch on theignition to show a sign of life but would not do any thing when I switch them on; just jerk a little bit. It is a point where they have stopped in the middle wind screen.
- The ABS light has come on from no where. I see people talking about the same issue and cleaning sensors. Can any one please tell where these sensors are?
Any help would be greatly appreciated.
thanks
