Welcome to JustAnswer, my name is XXXXX XXXXX I'm here to help get your problem resolved. The body control module actiavtes the low beam relay, so this most likely means body control module has failed. You unplug body control module and ground whtie wire at pin A11 o connector 2, here is a picture of body control module to help you access. Let me know if you have questions or if there is anything else I can do to help, thanks.
I want to say thanks for all information, but it ended up needing a headlight bulb blow.
