I believe you are talking about the PHOTO sensor!
GM calls it the ambient light sensor. The interior light intensity is controlled by the sensor input and the headlamp switch dimmer rheostat setting.

In short it controls the interior lighting and dashboard display intensity.

mucho gras. To interpret correctly, the photo sensor adjusts the dash lighting automatically while the rheostat control overrides it manually.

Appreciate your knowledge.
