2012 Enclave DRL's

My passenger side driving light is out. I replaced the bulb still don't work. Removed the good bulb from drivers side and installed it in the passenger side still don't work. Any body have a suggestion or a good DLR schematic. Any help will be appreciated.

More info. I see where the GMC acadia has a TSB 14823 on DRL's

Exactly what do you mean by a driving light?
