My windshield wipers arnt touching the window all the way throughout the wipe process. They wipe some but towards the outer sides of the window they come off the window by about an inch. Apporx 4 inches of the blade comes off on each wiper. Any ideas on how to fix it? Thanks ahead of time!

 

Get new wiper ams and springs.

 

Damn...Where can I get these? Please dont tell me directly from GM.
