It's the daytime running light module located on the side panel in front of
the passenger side door. You can try to solder the hairline crack on the
circuit board in the module or just disconnect the plug. Then you will have
manual operation of your headlights only. Or, just replace the module.

There used to be a web site that had instructions on how to repair this. I
can no longer find it. This message might prompt someone else to forward
the instructions.
