I have a question about my wipers. I've noticed when I have them on intermittent they change all the time. Is there some kind of water or rain sensor somewhere on the car? Because I noticed if I have it on the slowest intermittent setting, if it starts raining harder it speeds up. Is that normal? I've also noticed that sometimes it'll go from intermittent to like anywhere from 5:00 to 9 times and then go back to intermittent. Does that even sound correct?
