How do you change the windshield wiper motor on a 1998 Ford Windstar?

They guy above is right however I would phone ford and get them to check recalls windstars in that year had a recall for the wiper motor cover and it shorts out I would check first free repair.|||unbolt the wiper arms, take out all the screws and remove the cover over the firewall, unbolt, unplug and remove the wiper motor. installation is in reverse.
