Windshield wipers won't turn off on 2005 Mitsubishi Galant

Windshield wiper blades will turn on but will not turn off, or will turn off at random times. How do I fix this?

You probably have a bad set of contact points in the wiper motor or the parking paw is sticking. I would suggest that you replace the wiper motor to correct the problem.
