Running lights on trailer don't work

The running lights on the trailer plugs are dead. The brake lights and turn signals work fine. I have checked the trailer wiring on my new trailer and it is ok. I checked the wiring harness on the truck and there is no power there. I also checked the fuse in the inside fuse panel and it is ok. I was wondering how often the relay under the hood might go out. I hooked up an older trailer a few weeks ago and the lights worked when I started out but were out when I got home. Any help would be appreciated.
