4x4

[jbrunsvig]

Have a question for anybody that can help me... I have a 2000 Yukon Denali and I have started to notice that the lights for the 4x4 will turn off when it is in 4hi or in 4x2 mode. Does anyone know why this might be happening?

Thank you, I will give that a shot, dose anyone else have an idea?

Most likely it's just the switch that has gone bad, a fairly common problem. They are pretty cheap and easy to replace. You can find them on eBay for less than you'd get them from a dealer.
