Maybe try moving the offending arm one spline on the hub. I noticed when I got my vehicle the passenger side wiper arm was sitting too low almost allowing the blade to touch the scuttle, driver side was fine. Standing in front of the vehicle you could tell the wiper arms didn’t match or sit even when in the parked position. I moved the passenger arm up one spline to make them both even and haven’t had any issues besides the poor rubber quality of the blades themselves. Perhaps the wiper install person on the production line was in a hurry to use the restroom or something on my build?
