Hello everyone, if anyone can help me with this it'd be greatly appreciated. Our new-to-us 2010 330 E90 is exhibiting strange problems with the wipers. Once activated, whether by sprinkling water or just wiping normally, they wont stop normally. They'd just keep wiping, not responding to any stalk movements, and they'd abruptly stop anywhere but their end position, they may stop vertically or in the middle of the windshield. But never correctly.

Anybody have an ideas?!
