Rasm616 Posted May 25, 2022 Share Posted May 25, 2022 2017 F350 6.7 powerstroke. My wipers usually only work on high and the washer only works when all settings for wiper speeds work. Occasionally everything works normal for a few miles and then goes back to working only on High. Checked fuse. Any input would be appreciated.

SpartanFan23 Posted May 25, 2022 Share Posted May 25, 2022 Sounds like a visit to the dealer is in order. Are you still under warranty? Quote Link to comment Share on other sites More sharing options...
boarslayer Posted May 26, 2022 Share Posted May 26, 2022 Mine only worked manually. I noticed auto wipe would work if I squeezed the box above the mirror. I could make them work on demand. Maybe not the same problem as yours but the dealer had to replace the sensor module and now my wipers work perfectly. Quote Link to comment Share on other sites More sharing options...
4thTimer Posted May 27, 2022 Share Posted May 27, 2022 Do you hear the motor trying to work at lower speed? Quote Link to comment Share on other sites More sharing options...
