Hello Hello, after driving to work this morning in the rain, my passenger side wiper decided to stop working, having inspected it, i noticed that the bolt holding the wiper on was loose, so i tightened it, which then sent the other wiper crazy, and was going off the edge of the windscreen. Have got it back to how it was now, checked the wiper arms under the bonnet and they all look ok,

And ideas? maybe need new spindle bits?

Are you sure that the wiper motor or its drive spindle are still where they are supposed to be?
