I have an old shape Berlingo and the wipers go click at the top of their travel. On long journeys it does my head in. I thought at first that they were hitting the bodywork at the side of the windscreen but this appears to not be the case. Could it be a gearing/spline problem. It makes no difference with new wipers or the speed at which they are run.
Any idea's as it's driving me mad
Click....Click....Click aaaaaaarrrrrgh
