Entire Instrument cluster flashing

[midnight runner]

I took my 06 to get detailed today. On the way home, I noticed that the entire instrument cluster was flashing(Whatever gear I'm in, ride height, speedo, tach). The RSCA, and foglight indicator stay solid though. This all stops when I turn the headlights or parking lights on.

I can't find anything in the manual or online anywhere.
Does anyone have any idea what can be causing this?

BTW, this isn't a slow normal warning flash. This is the fast twitching kind of flashing. It also changes pace. none of the other warning lights come on like the abs, vsc, etc. Those all stay off.

wow! I don't know what could cause that problem. Try and pull the codes and see what they have to say. After you do that, disconnect the battery for about 15 mins. and see if it clears up.
Does it affect anything? Good luck! Let us know what you find.

It's weird. I was playing with the dash dimmer, and now all is back to normal. Maybe the dimmer knob got thrown down too hard, and went to a level that was barely sending current to where the dash was flickering like a florescent that is about to go out. Anyway. It's all good now!
