Turned the wiper on the other day during a light rain. Worked fine although the intermittent function wasn't there. Arrived at my destination and the wiper would not turn off unless I shut the ignition off. When I got home I checked the four fuses and reseated them. Wiper still wouldn't turn off when I turned the ignition on. Checked the relay and switched it with another like relay. Still wouldn't turn off. Considering replacing the switch on the steering column. Any suggestions would be deeply appreciated. Thank you in advance!
