A few months ago one of my wipers was coming loose, and while using the wiper blades it slid off and went straight upwards. I think when it did this it moved the whole arm of the wiper blades up, because now when I turn off the wiperblades, they do not sit under the windshield anymore. Instead they sit about 6-8 inches higher than they should. This means when I turn them on when it's raining, they aren't staying pressed against the glass because their positioning is wrong, and the driver's side one nearly goes off the side of the windshield when it is fully extended.

I'm not the most mechanically inclined person when it comes to these kinds of issues. I've included a photo. Anyone run into this before or have any diea how to fix this? Thanks in advance.
