Stupid truck....

I'm not going to read all the reply's, but I had a similar problem with my 05 dually. The little saddle bag jumper right below the steering column had just worn out and didn't make good contact. I took the back up one from the owners manual baggie and inserted it and it's worked fine every since. I took it to the dealer and they also said they saw no errors.
But that's what it was....
