KWT660HDT Posted May 14, 2016 Report Share Posted May 14, 2016 So today my wipers decided to start working on their own. They still respond to the switch if i set intermittent or continuous they work as expected but I can't shut them off. If I move the wiper switch to off, they work randomly anywhere from once every 10-20 seconds to non-stop Bad motor? Bad relay? How can I tell which is the culprit I tried pulling and putting the relay back in that did not help nor did did cycling the ignition Any suggestions would be appreciated Thanks 2013 KW T660 485HP, 18 speed & locking tandems 2015 XLR 45' Toy-hauler Link to comment Share on other sites More sharing options...
Scrap Posted May 14, 2016 Report Share Posted May 14, 2016 Go to the ground stud on the LH frame under the hood. Then go to the inside side of it all and make sure they are all clean, tight, and terminals in good shape - especially the little one that comes down from the firewall. Loose/missing one there can cause a ghost wipe. Most importantly, check with your dealer to be sure the wiper motor recall was completed. Get that done if your truck needs it. The stud is the one on the bottom right of the wheel sticker in the pic, but on the inside of the rail. Link to comment Share on other sites More sharing options...
