And always the driver's side. Happened on my SAAB 9000 which uses a different part but the spindles driving the wiper arms are always made from soft metal. I suspect this is both sacrificial in case the arm gets jammed and practical in that the spindle mounting metal has a high friction characteristic.This happened to me the first time it rained after I bought my car. .....
Unfortunately the serrated arms appear to be made of the same crappy pot metal as the door handles ....
I was surprised after posting about this that I got so many replies of "Oh yea, happened to me too" Seems that nearly every seasoned veteran 164 owner has experienced at least one wiper failure and of course it only happens when it rains.![]()
