My 2007 yukon has no dash instrument lights during daylight. The only gauge illumination is when the headlights are turned on. During daylight, the gauges are impossible to see with sunglasses. And almost impossible to see without sunglasses. This is very dangerous because you have to take your eyes off the road for a considerable time to view the gauges. I have taken to the dealer and GMC; they have no answers.
