Haywire,
Your instrument cluster may need to be rebuilt/replaced. I had my replaced through a company that does this for GM. However, the cluster is no longer available to be ordered through GM. Only this place: http://www.instrumentsales.com/remanufacturing/ Call them up, they will tell you what you need to do even though you are not a GM dealer. It will cost about $250 roughly. It took about a week for turn around time. My cluster works great! Bluethunder 1998 Tahoe 4WD 277,000 miles |
