How to replace wiper blade rubber insert on 2012 v?

No screws.
I find that if I try to replace the rubber while the metal arm is attached to the car I lose patience. So I detach the arm and sit down comfortably at a table in the house. Then it is clear and easy.

Do keep in mind that you have to reuse the metal strips.

This is what I wrote for myself some years ago. See if it helps:

 

I agree with SageBrush, first remove the wipers from the car ... much easier this way. I just replaced the wiper blade rubber inserts on my v this last weekend--very easy. There is a notch on one end of the insert ... look at the notch on the new insert and you'll see that it obviously has to be inserted into the metal bracket in one direction ... just pull the insert in the opposite direction to remove.
