So I've been trying to replace my rear wiper blade for awhile now, but I can't get it off.

I watched the on how to remove it, but mine is completely stuck. I can remove the cover and the bolt, but when trying to remove the actual wiper arm, I feel if I pull it any harder than I did I would shatter the glass. I've been spraying the area with PB blaster every day for the past week, in the hopes that that would help, but no luck at all. The rubber lining thing that goes around it is also bent and pulled out, not sure what caused that as it was already like that when I bought the car last year.

I can get some pictures up tomorrow morning.
