Rear Wiper Replacement

This is an idiotic question and I apologize, but how do you get the rear wiper blade off to replace it?! Unlike the front wipers which have the hook-type, the rear is a pin. I cannot get the wiper blade assembly to come off the pin. Any suggestions?

look for a little hole, right were the pin goes through the
blade. use a small driver to push it while pulling the blade off.
