How to fix rear windsheild wiper - ML320 2001
 

Greetings,

I need help on my ML truck. Saw the next day after it rain and using my wipers the rear window wiper has dropped down near the tag area not upward on the rear windshield -- see picture to better describe what I am seeing. What should I do? Where do I go to get something like that fix? Could it be something I can fix? I have yet went to turn on the wipers yet. I wasn't sure that would mess it up more.

Any help will be greatly appreciated

As you can see the rear wiper is laying down too low and near the tag area. This seemed to happen a day or so after using the wipers due to slight rain in the area. What could be the issue? How can I fix it?
