Windshield wipers

[Mr. Nosidda]

My windshield wipers seem to be over powered as they will sometimes hit the very edge of the window, creating a loud thunking noise. This happens intermittently in winter and normal mode. Does any one know the cause of this?

Maybe out of adjustment, wrong size, or switched at birth
