Wiper motor won’t shut off?
Mark clocking position of the cover to wiper motor body to put back in the same spot. Take cover off and see whats broken inside. You can find the wiper parking switch new on evilbay all the time, or you can buy a refurbished/restored 3 speed motor typically for several hundred dollars, or you can take the time to figure out and refurb/repair yours. Irestored mine in the pic myself. Was still into it for over $150 in part because i wanted to re cad plate the motor cylinder. The clocking position on the motor determines when the switch opens and kills power to the motor to park the wiper arms.
