I have a 2004 Suburban that has ongoing issues with the 4X4 system. Sometimes the 4X4 system works and more often than not it doesn’t. The issue is that the LEDs on the 4 button 4X4 selector switch are not illuminated when the vehicle is on. They illuminate initially when I cycle the ignition but then go out. Pushing the buttons do nothing. Also, the “service four wheel drive” is showing on the information display. I have done the following: Replaced TCCM, cleaned grounds on frame near drivers door, replaced 4 button selector. Any advice would be helpful, Thanks.
