Check this thread.

“This failure is going to be the smart junction box. The multifunction switch is telling the body control module you want high beams and the BCM is telling the instrument cluster via the bright indicator. That leaves the SJB that powers the high beams to blame. There is not a headlight fuse to check.”

“The SJB is the fuse box under the left side of the dash that has an integraed computer in it. It requires diagnostic tool programming to replace it.”
