I just got a 2010 with built in brake controler, when I plug up to a trailor a no trailor brake light comes on. Brakes worked fine on old dodge . Anyone had this problem yet? Dealer had no idea told me to watch the CD about truck and then if I didn't figure it out just drop it off with them!

The DVD has a ph. # to call for full paper manual. Much better IMO.

Don't know about your brake problem. Mine works fine.

Must be the way you have the brakes wires up on the trailer.

Are you using a 7 pin or a 6 pin with a converter to go to your trailer?

Working fine now, pulled it down the road and is working great, maybe a bad ground.
