The headlights run through a relay (#46) through the BCM. If the relay were bad (very common and has a recall) both lights would not work. Sooo, I'm thinking check the wiring and pigtail that goes to the bulb. People that use Silverstar halogeon bulbs will burn that wire and or the connector. Make sure these are sound, check for power at the connector too.

SOURCE: passanger headlight bulb inop
disconnected the HID ignighter. used a T20 to remove bulb cover. pulled out bulb and installed new bulb. DO NOT TOUCH THE BULB WITH BARE HANDS!!!
SOURCE: headlights wont come on, but parking lights work...i dont get it
Was sent in by another poster, just posting his results which fixed mine. Problem was relay $50.00 at GM only.
Check the relay module. 45 or 46. on the engine relay block. you can
swap the two they are the same part number, then you will know. Dont
start the engine, just check the lights. If it works replace the relay
module. You may have to order the part from the parts store. Or go to
the dealer to get it.
SOURCE: Headlights ok, but instrument panel,fog,&parking lights don't
Maybe a relay but maybe and more probably a broken wire Get a diagram Chilton or Haynes manual
SOURCE: Within the past month, both
Have you replaced the multi-function switch? It is common for it to stop hedlight funtion and allow other funtions to keep working.
