The computer had to be reset. Had the same problem and thought

it was a sensor but only took the computer being "reset" by the

dealership. Cost $200 in Dallas area.

The problem is not with the computer.

this is a common problem on all 03-06 GM Vehicles

if you wanna get it fixed Just go to They fixed my instruments cluster on

my 2004 Chevrolet Silverado. They charged me $150 to replace all

the gauges in the cluster. here is the address in case you wanna
