Help Removing Wiper Arms

Does anyone know how to remove the wiper arms?



I took my car to the dealership and they removed my wiper arms during maintenance but didn't put them back in the original position. I can see my wiper blades when it's in the off position which is bugging me. I'm a bit OCD when it comes to my car.



I removed the nut at the bottom of the wiper arm but can't get the wiper arm off. Any ideas?



Thank,

CM
