Welcome to JT Hughes. We're looking at the Santa Fe. And I'm going to show you what to do if your windscreen wipers are smearing and how to check them and clean them. What you need to do is you lift the wiper blade up. Get a cloth with either some warm water or some screen wash on. Run it down the length of the blade, pop them back down. Try them again. If they're still smearing, then you may need new wiper blades. Give us a call, and we'll be able to assist you from there.
