Pennyrile, West Ky.
It sounds just like a squealing wiper blade only its constant, as the blades stop temporally to change direction the squall continues. It sounds like it's coming from under the black plastic piece that's under the wiper blade drive shafts. I assumed it was all gear drive but maybe it's not, is there a belt under there somewhere?....TIA, John
