2L8IWIN,
The instrument panel intensity control may have been turned down by accident. It is common to brush it getting in or out of the vehicle.
You can brighten or dim the instrument panel lights by turning the interior lamps thumbwheel.
Turn the thumbwheel to the right to increase the brightness of the instrument panel lights and to the left to decrease the brightness. Turn the thumbwheel completely to the left to turn them off.
Please refer to page 2-54 of the owner’s manual. For your convenience, a digital copy of the manual is available at: http://www.extendedgmwarranty.com/ow...-GrandPrix.pdf
If you have additional questions or concerns, please feel free to contact me privately.
