The wiper motor will not stop running regardless of the switch setting. Everything was working just fine. The switch new and is OK. The motor is new and OK. I took the motor out and put in back in the park position and reinstalled the motor. Some of my wiring diagrams show a diode on the connector and some don’t. I don’t have a diode on mine. Anybody have an idea of why the wiper motor will not shut off?

Thanks Joel, it makes sense the problem might be a ground issue. I have the intermittent wiper switch and it did not work well but the wiper motor did start and stop properly with the switch. One day it just stopped working. I suspected the switch since the intermittent function had issues. I was lucky enough to find a parts dealer in Canada that had some. I replaced the switch and it didn’t fix the problem. After doing some more troubleshooting I suspected the wiper motor just would not go into the part position. I have seen this problem with other cars so I replaced the wiper motor and it did not fix the problem. I’ll have some garage time tomorrow to start looking at a ground issue.
