windshield wiper

i have a 92 prelude and the drivers side windshield wiper has been going past the window when it wipes to the left, which causes it to get stuck in the up position. i took it off and tried to position it at a position lower than normal when it starts. that worked for a while, but today in the rain it got stuck again, and i almost killed myself. i can grab the wiper and pull it far past vertical and past the window. does anyone have an idea for how to make the wiper stop at the vertical position, so that i can avoid a premature death. thanks for any help.
