I got my 05 2500 a couple months ago and noticed there was something wrong with the wipers. When set to on interval it will run at it's set interval then wipe a couple times without stopping then go back to normal again. I also noticed when I turn them on that sometimes they will not work at all unless I turn them on all the way. Anyone have any clue what could be wrong? Any help would be greatly appreciated. They are really starting to annoy me.

 

Bad multi function switch?

 

Mine do the same thing. There was a thread about this a few months ago. I don't remember anybody ever giving a fix though.

 

mine does it too. there isn't a know fix. Some have been fixed with a new motor and some have gotten better with a new switch. If you get yours fixed please post what you did.

 

reminds me of past troubles with my old chevy, turned out to be prone to having a bad ground, set up a new ground to the wiper motor and it worked again.... easy enough to try.
