The parking function of the wiper motor is defective.  I would replace the motor if an adjustment does not correct the problem.  You see, when the wipers get to the park position and the switch is in the off position the contacts are supposed to stop the motor from running the wipers.  Also, when the wipers start this park function is supposed to allow the wipers to start.  If you have to pull on the wiper arm to get them going the contacts are defective for the electrical connection.
