wiper arm removal?

If you look at the base of the arm, you will see a little lock sticking up at the top of the base. You lift the arm off the windshield, use a small screwdriver to pull that lock out, towards the windshield, while pulling the blade away from the windshield. This will lock the blade away from the glass, then gently pull the base of the arm off the wiper trannsmission.
 
uhh can someone explain this a little better, maybe even pics , tell me like i'm retarded lol.

When i look at mine it looks like it has two little screws on the bottom that i have no way of getting to. I don't see any type of "lock".

It ""kind of"" makes since what fett said but i've been trying to figure this one out for quite some time.
 
Don't sweat it - I strugged with the first one I tried when removing it for the first time. It was seized to the hub, as A.S. noted can happen.

Good luck.
