Turned on the truck....I have no gauges. The DIC works but all the gauges are "0". Truck is at about 66K now. I know this has been a problem for some. My buddy had this happen some time ago when he was under warranty. My questions are.... What basic things can I check before taking it to the Dealer or shop? Fuses? (If so, where would these related to the instrument cluster be located?) Anything other than fuses? Is there a TSB on it? Given GM's money problems my guess is they won't do anything for me. thanks in advance for any suggestions

Check the batteries. You probably have one thats worn out, and the cluster has to "see" a certain voltage to "wake up".

I just put in two Duralast Golds 4 months ago. But I will check them anyway, you never know. Thanks

I think there was something about a reflash for the Instrument Cluster too, maybe in the TSB's.

And you have a 03 seems most of the cluster problems have been 03's

they currently have 2 concerns... 1 is for all gauges inop, which is a reflash and another which needs the cluster sent out for repair. if you want to try the fuses, the ones you need to pull are under the hood. IPC/DIC, SEO B1 are the battery fuses. IGN E and SEO IGN are the keyed power fuses

Oh, ok. Better to check the simplest things first.

Its interesting, because the IPC came back on when I started it for the fourth time, then it went out again, and then the next time started up again and has been working for 2 days now. Makes me think that maybe the reflash would do the trick. The reflash is supposed to reset the IPC's operating voltage to a lower value.
