New to the forums, and sort of new to this old wiper setup.. So my wipers used to work, except have some problems stopping. Now they completely don't work, I replaced wiper motor and they still do not work. The piece that the wiper arms connects to (don't know the name of it, it's sort of like a bolt sticking up that move the wiper arms) is stripped, could this be the problem? Should I replace the entire wiper linkage?
