It sounds like there is a short somewhere that you will need to track down and correct. A short would cause constant power draw and could explain why the lights come on and stay on. Make sure the vehicle and trailer side connectors are clean and free of corrosion. Inspect the wiring from the front to the back and look for any frayed, pinched, or damaged wire and repair as needed.

I have included a couple of helpful links on testing and troubleshooting wiring for you.
