The problem is with the one-swipe function. When it happens they only wipe once or twice, it's not like they come on and stay on for a while. It happens while I'm using the one-swipe, like driving in very light mist. If i tap it for one pass, it will do one or two, then maybe again without me touching it. I grabbed a spare wiper control from salvage a while back, I'll get that one out and investigate.
