Old question, new answer... It's most likely the "Headlight Driver Module". GM has a new recall on it May 2017, something like 12 years/150,000 miles. If you have to pay for one, they're available anywhere, maybe $40. It's in the underhood fuse box, one of those relays in there. It's a 3-minute job to replace.
running lights not working. how do I replace the bulbs? or could it be a fuse blown?
