Check fuses in the diagram. Not only check fuses, check voltage on fuse circuits. The park lamp relay has to be energized for second fuse to go hot. The bcm grounds the coil side of park lamp relay. The bcm needs input from the headlamp switch. I didn't think to check for lighting trouble codes. Are there any applicable codes?
