there is a separate circuit for trailer lights. need to get out your owners manual and find all the fuse box locations. you are looking for "trailer taillights" or something similar.

Have the same problem 2010 ram 1500. There is a circuit blown in the power module. If you have the money the dealer can reset this and bump the amperage up on that circuit i have read. Problem is they will probably tell you they havve to replace the module($800). I don't believe this is true but the starscan tool to reset it yourself is about $2000.
