I have replaced my wipers because they were worn and bouncing over the windschield, with Bosch wipers. Now there is a loud clicking noise at the drivers side wiper, at the top of the stroke, when the wiper changes direction. I checked the angle of the blade on the windshield, this is in rest 90 degrees, so I gues this is ok. I tried anothe brand of wipers as weel, same problem. See the video for an impression. Anybody any ideas? Or have the same problem?
