What controls the auto intensity of dashboard lights on a 2002 Corvette Z06?

The auto-intensity of the dashboard lights on a 2002 Corvette Z06 is controlled by a light sensor located inside the instrument cluster, usually behind the gauge cluster itself. This sensor detects the ambient light level and adjusts the brightness of the instrument panel illumination accordingly. The system is entirely automatic; there's no manual adjustment for the auto-dimming feature itself, though the overall brightness might have a range adjustable via the dimmer switch.
