Did you check for voltage at the bulb circuit? The headlamp switch sends signal to bcm, bcm sends data signal to front control module, front control module controls headlamp driver. In the diagram, the top wires are voltage for high and low beam at the headlamp. Bottom wire is ground. Check applicable fuse/s for front control module. Check for applicable trouble codes.
