I know i'm a dumbass, but how do you change the wiper blades on a yukon? I have an 05. The wiper arm only comes off of the windshield about 4-5 inches. It's not enough to flip it. I've done this on every other car i've owned, but I can get this one. The hinge that let's it come up is hitting the bottom near the cowl. Any help is appreciated.
