Myh intermittent has dissappeared. When I mist the wipers, they don't return to the normal spot, they stop when I let off of mist instead of returning automatically. When I put the wipers into int., they go to a low setting. If I put it back to off, they don't turn off. I have to click mist or go back into int. and back to off and, again, they shut off where they were. My high speed works fine. What the hell is going on?????
