I just went through the wiring schematics and if you have power to the left DRL, the right should have it as well. They receive power from the same point.
Take a look at the attached pic. There should be a dark blue wire that powers both. Note that they split from the fuse box, but both have the same power source. There must be a break in that wire at some point. I would start tracing it back until you find where the break is located.
Let me know if that helps or if you have other questions.
