Hi all, I own a 2017 mustang ecoboost premium 19700 mileage on it. I noticed some scratchy sounds (Krrrrrrrrr Krrrrrr Krrrrrrrr...) coming from the right door when I drive at 50 mph or up and the sound goes off when the speed is lower than 50mph. The sound is like the atm machine sounds when it process the cash withdrawal (Krrrrrrrrr Krrrrrr Krrrrrrrr... and it goes on). Don't know what to do. Please need your help and advices. Thank you.
