I have a 2013 Sportscoach 405fk, freightliner chassis XCR. There are two switches for the wipers, low and high speed continuous and intermittent/wash. The low/high works fine, but the intermittent does not, but the wash function does. The intermittent switch has been replaced, still does not work. Should there be a relay for it. Looked at the fuse block. It has a spot for relay on the wipers, but none there. All marked opt. Thanks for any input on this.
