The back windshield wiper on my 99 Ford Explorer doesn't make contact wtih about 85% of the window. The wiper cradles properly and all of the parts seem to be working and in good condition. Has anyone else epxerienced this problem and how to fix it?

 

Yes, i have the same problem with my 2000 ford explorer's back windshield. If any one knows how to fix this, please advise...
