Eric,I just talked to my son-in -law he was a Diesel mechanic in the USMC,he thinks he knows what it might be,but the relay is a good starting point.Can't go camping until I figure this out.:nod:

i had a dodge 2500 that did the same thing and it ended up being the daytime running light module unplugged it and no problem except no daytime running lights (no big loss)
. Is their something like that on a superduty because you can check by just unplugging the module
