How to remove rear wiper blade

[emolina]

I need help. I had changed the rear wiper blade to an Anco years ago. Now, I can't get it completely off. I pressed the tab but it is still stuck on part of the pin on the wiper arm. Any ideas? I don't want to break the whole arm. Thanks.

[.]Press the tab firmly enough. If you cannot do that, you might wanna spray it down with WD40 or something. That's all I can think of what you can do. Keep working it. It'll come loose.
