well, i dont run the wipers on high, so i wouldnt know.

when the truck is idling or driving at low speeds, the passenger wiper swings out to a "normal" position (about 12 o'clock or so) and then returns to the bottom of the window.

when i'm driving above 35 mph or so, it seems the passenger wiper arm swings out further--eventually swinging out so wide that it crosses the edge of the window and gets stuck.
