Try a new bulb or the bulb from the right headlamp. Is this vehicle HID and auto leveling ? If so I have a good used assembly for sale , if that’s what’s needed.

Check rear lamps. We got spun around once by a front control module high RH headlamp circuit code that turned out to be a broken rear brake filament that came to rest on the intact tail filament and caused a short-to-power that bled upstream to the headlamp circuit.

Glenn check that headlight ground. Also Check the headlight positive with harness unplugged and key on and light switch off check and see if there is 5 volts. With a good bulb and good ground that will get pull down when plugged in to the bulb.
