Adjust windshield wiper arms so that the blades return to the normal off position?

Wipers on my 2006 cobalt bounce across the windshield, if misting or pouring rain. Not as bad when sitting still as when moving. Dealer first put Rain-X on windshield, then new blades, then new arms & blades, then another new arm & blade on the drivers side. Still bouncing, sometimes so bad, it's like not having any wipers.

I have a 2006 Cobalt and the windshield wipers stopped working midway through a cycle. I can hear the motor, but mechanically something disconnected. I read somewhere that there is a clip that connects the wipers to the motor. I am thinking that this is my issue. I would like to fix this issue on my own, but don't know where to start once I pop the hood. The person who described the clip issue said a mechanic showed them how to fix the problem and that it looked fairly straight forward. Unfortunately, that person did not elaborate on steps to do this. Can you offer some insight/details on how to go about this?
