Wiper problems of the 2001 Mercedes Benz SLK230

Vehicle type is 2001 Mercedes Benz Slk230 (r170 model). The inside rear view mirror is an electrochromic self dimming mirror that has no manual backup. The mirrors fail losing their ability to provide dimming against rear approaching headlights causing the driver to either be blinded or to have to turn the mirror up and have no rear view capability. I know of many documented cases of these mirrors failing including my own. Some fail by just quitting working while others leak the internal fluid.
