having a problem with my passenger side windshield wiper/ driver side as well i guess, seems to only have ONE speed (fast) and it will go up and down 3 or 4 times then get stuck in the middle of the window until i press the wiper button again.... in addition, my passenger side wiper has decided not to move more then 3 inches from the resiting position.... is this just the wiper motor? or is it more, and is it an easy fix?
