Windshield Wiper Issue?

For some reason, my passenger side windshield wiper has stopped, but the drivers side one works perfectly fine. When I try to google this question, I get no responses really. Im thinking its the wiper motor, but why would only one of the wipers stop if thats the case? Any help would be great, thanks
Update: The car is a 2003 Hyundai Elantra. Thanks for all the help everyone
