Windshield wipers only work on high

[Smokin 6.0]

I’ve got a 2018 F-350 that my wipers only work on high. The squirter works and when you push it the wipers work on that speed aswell. I replaced the multifunction switch and same thing. Wiper motor ???

By the way, for newer trucks, systems like what is ADAS? can sometimes be affected by windshield or wiper issues. Wiper motor ???

Your wiper motor is likely bad. The low-speed circuit inside the motor has failed, which is why the wipers only work on high. Replacing the motor should fix it.

I've seen the answer be at the fact that the wiper motor is bad...but dumb question...probably only on the older vehicles...I think there is a RELAY between the control and the wiper motor....am I wrong...also I have all names.....Chevy, Dodge and Ford......so ??????
