Hey there man. Just a routine question with things like this but have you checked the wiring? Made sure everything is plugged in and has a good connection? Next thing I would check is if you're getting power to/from the controller.
Cajun Dodge thanks for stopping by. I do have a question one my oem break controller. I can manually lite the controller if I use the slide. If I hook up camper it will not see it on the controller aka say I have a trailer hooked up. Break light work on camper. Is the controller bad? Thanks
