Mine is a 2006 also and just did it for the first time. The only thing is I have done new was plugged in to the OBD2 port for gauges on my Dashboss. I think Snuggyworm might be on to something. How many of you guys - girls have it happen when something is plugged in to the OBD2 port?

Same here.... mine has done it with nothing plugged into OBD port and I also have steering wheel controls. I also find if I cycle my remote car starter/alarm it will bring the cluster back to life.

this is my own personal research, and I will be the first to admit I am under qualified to make this assessment. But What I have come up with This only happens to 04-06 Excursions, 250,350, Lariats and King Ranchers all have climate controls in the steering wheel. A few years back me, a buddy and a bottle of Ky finest tore into my dash while my ac unit WAS NOT working. I did not shut off the truck, nor did I cycle head lights. When we reached the back of the ac/heater unit there was no power to the hot wire according to the test light, I reached over and turned on the head lights, and power was restored to the hot wire and unit kicked on. I have learned since then that some Excursion,250 and 350 have a different wiring system. (Bismics spread sheets back this up) I dont know the difference I wander if it is the ones with the controls in the steering wheel. I also read that there is a relay that gets lazy and need the extra current draw(from cycling head lights or remote starter) to trip. Just my opinion.
