For any others out of warranty, Ebay is a viable option. I remember USPEEDO as one vendor.

The small stepper motors that drive the individual gauges cost about $10 each. The rest of the cost is in labor and they must soldered out and then in again. A dealer will NOT play with the cluster. They will want to swap it out for the big dollar fix.

 

i have a 2004 ESV and my cluster was all out wack. now considering that it was over 70k GM will not fix it...however i went on ebay and found a repair company where you take out ur cluster and send it to them and they repair it...now i didn't know how to take it out and i didn't want to wait to get it back..so i called the one nearest me and the guy toldme how to take it out and i did and instead of mailing it to them i drove it to them and they had it fixed in 45 mins and it only cost me $60 AND THEY REPLACED ALL PARTS INSIDE WITH A "LIFETIME WARRANTY"...CAN'T BEAT THAT...

 

does this mean there where cars that the odometer was faulty too when this went bad and the car you bought thinking it had 30k actually could of had 130k miles
