Do you guys have any idea how to troubleshoot this, if it was only one side I'd start by replacing the bulb but since it's both I suppose they would not both go out at the same time?
If the the car detects a problem with one of the daytime running lights, it will discontinue use of both of them. Replace the left bulb and see if they work. I had this a few years ago. If I remember right, the computer might need to be reset by dealer.
