The first thing you will want to do is test the running light pin on your trailer side trailer connector. If you don't have power here then you know you have a bad fuse most likely. If you do have power on the running light pin for the trailer side trailer connector then you can move onto the trailer. The first thing I would check is the ground for each taillight but if this still does not resolve your issue then you will need to trace the running light wire from each light up to the trailer side trailer connector to check for shorts.

I have attached a help article on the above for you as well.
