My rear wiper motor went kaput. I’ve gotten almost everything undone, but there is what looks like a smooth round black retainer nut holing the shaft in place. But that retainer nut doesn’t have any flats that I can put a wrench or socket onto. Instead it has a small groove on either side that I tried to use with a flat tip screw driver and hammer to loosen, but no luck. Is there a special tool for this wiper shaft retainer?
