Sure, the DRL's are controlled by the BCM which signals the DRL relay to turn on the DRL circuit. Also, there are two fuses I need you to double check, IGNE and DRL in the fuse panel under the hood, here are two guides to help, if you don't want to test the relay you can just swap it out for a new one.

Here are the fuse and relay locations and I have included the DRL wiring diagram as well so you can see how the system works.
