Silly question, but did you make sure the DRL bulbs are not burnt out? (At night, the DRL's won't come on. The optical sensor on top of your dash will instruct the BCM to illuminate the Headlamps only. If the DRL bulbs both burn out, and it is daylight, you won't have running lights while in gear). If you have already confirmed the bulbs status, disregard.
