Couple other things to note: while I was in there, I noticed the cabin air filter was a disaster.....so I replaced that too. Also went ahead and replaced the air filter at the cold air intake box. Also replaced the little round plastic caps that go over the windshield wiper hex bolts.
In terms of pulling the wipers off.....well, I got one off with my hands. The center one wouldn't budge though. I pulled, and jiggled, and rocked, and wobbled...until my hands were bleeding. Then I gave up and ordered the tool for prying off windshield wipers and stuck battery terminals. That part sucked, but that tool was make it way easy.
