The way the wiper system works is the motor always powered by a hot wire and the wiper switch removes the motor's ground when it is off. There is an internal partial ground in the motor that removes the ground when the wipers approach the parking position. So your motor's partial ground is broken or the wiper switch is not removing the ground when the switch is off that could be your problem. There is another possibility and that is the intermittent control for the wipers is broken. Again this control supplies a intermittent ground to the wiper motor. If is supplies a continuous ground to the motor the wiper will continue to work. Usually this is caused by a stuck intermittent wiper motor relay.
