My suburban’s speedometer stopped working, the odometer continues to count the miles, but the speedometer does not work, it is stuck at a number or at the bottom “0” Do I need a new dashboard console or is there another part or need of repair???

There is a TSB for when " gagues become inoperative" I don’t know if this also means speedo. The fix is a PCM ref-flash. A tech with a Tech 2 could do a gague sweep and help narrow this down. 03-08-49-020
