Did you check for voltage anywhere? Did you check for voltage at the fuse circuit? Neither high or low beam will work? Our database info says bcm controls ground side of headlamp relays, so check for applicable trouble codes. There are headlamp control codes. I believe those are B type codes. Some of the national brand autostores will check codes for free. Let us know.
