Very annoying wiper chatter...just replaced with the correct Bosch blades...still driving me crazy...any suggestions??? thank you!

 

As you probably are aware, the wiper blade flip flops when the wiper changes direction.
If it does not do that, the wiper arm needs to be adjusted so it does do that.
All it takes is a little twist in the direction you want it to go. The wiping edge should trail in the direction the blade goes , if it leads, the wiper will chatter and not clean very well.
I hope I understood what you were trying to ask.
