lb7 cluster

I have an 02 lb7 and a very days ago all the lights in my gauge cluster started flashin and the gauges all went crazy and then stopped working and went to zero some times while driving they will pop back on for a bit the go crazy again ive did a gauge sweep with a scan tool and everything seemed ok any ideas?

Mine does it randomly and generally is for a second then going back to normal, sometimes I lose everything but RPM, Speed, and Oil pressure, the fix for that for me is to either pull the cluster out and put it back in, or just disconnect the battery's. I hope this helps.

If it's happening while driving, I'd lean towards a loose or bad ground. If the IC checks out fine on the scan tool, then that's where I'd start. Grounds then 12v supply.
