    May be the insturment cluster

    I don't know about 2500 series, but I just replaced the cluster in my 03 suburban. Had the same problem or it wouldn't work at all. This was done at no cost to me because it is a common problem, but it may be different for a 2500 series (I'm assuming truck) and being a different model year.

    thanks for yalls help, i found that the stepper motor was bad in the cluster. dealer ship said had to replace cluster. but i bought stepper motor online and repaired myself for cost of 12.50 instead of 600 for new cluster
