2004 Envoy Tac And Speedometer

[ruup4it]

HELP!!!

My speedometer and Tac was not working good (off and on) and when i accelerated the speedometer would tick up like a clock insted of a smooth operation...I had the cluster changed it worked fine for about 3 weeks and now the hole thing is acting up again but this time both the tac and the speedo.... the tac somtimes spins completly around and i have to start and stop the truck to get it back to the original spot and the speedo somtimes just quits all together but i notices in the morning it is fine works good but if i drive for a long time it messes up ....cool the truck down and works good????

HMMM, Did everyone get their new replacement instrument cluster from their dealer? You guys know that all you have to do is tell the dealer you are having instrument panel issues and the dealer will replace the cluster free of charge, no mileage or time limit (at least for 03-04 gm pickups, denalis, yukon etc.) you may have to be firm with the dealer, but they will replace the cluster. this would be a good place to start, IMHO
