Instrument Cluster DIC Display Dims

The Driver Information Center (DIC) display in the instrument cluster of some 2014 Silverado 1500, Sierra 1500; 2015-2016 Silverado, Tahoe, Suburban, and Sierra models, equipped with the base instrument cluster (RPO UDC), may dim or fade when the interior is very warm — due to sun load or extended heater operation — or after extended vehicle use.

The DIC display is designed to dim with high temperature exposure in order to protect the display from damage.


If the DIC display is dimming due to high temperature exposure, it is operating as designed. No repairs are necessary.
