Well, I talked to the local GM parts department and they said I can change out the relay, so I did and that didn’t work. I changed out the switch and that didn’t work. Really don’t know what else to do. None of the area dealers have a fuse box as they are all on back order. It’s past the 36,000 mile bumper to bumper warranty.

Thanks, I’ll check it out this afternoon

I just bought a 2018 Sierra 1500 slt a few weeks ago, yesterday I went to shut the wiper off and they don’t stop. They work on high and normal speed but no intermittent. I can’t find a relay for it in the manual, do I need to replace the switch?
