wiper arms are loose at rhe shaft on 2003 Honda CR-V

this happened during the snowing

Asked by for the 2003 Honda CR-V
The shaft is what is known as a wiper transmission. It is likely knurled with little teeth and has threads at the top that a nut tightens on to. Reposition the arm to correct position and tighten down the nut but not too tight. Do not want to brake off the threaded stud. Should be a cap that flips over the nut that you will have to flip to gain access.
