Hi folks
My wipers are playing up. The internal transmission is working great and the arms turn fine - to begin with. But after half a dozen wipes one of the blades sort of swivels out of position, and then the whole arm comes of the circular track and flops down loose (i.e falls off the external part at the root of the wiper, where it links to the driver mechanism). I'm guessing this is all to do with having non-original blades, but it could be a deeper problem. Any suggestions?
Thanks.
