Neither hi or low seem to be halogen flavor not hid from fuses.
All went at once no difference auto or manual switch no blown fuses.
Fog lights work (different fuse).
Running lights all work.

Good morning

Did you check for power to the headlight connectors for power with the lights on? Use a voltmeter or test light.

I attached a diagram of the headlight system for you.

You need to check the fuses I circled for power on both times. There are relays controlled by the body control module for the lights.
