Sounds like the speedometer assembly in the dash cluster is fried. You will need to get a rebuilt unit, available from various places online (search google for "Suburban dash cluster rebuild" or similar) or get a factory unit from a GM dealer. You may want to go for the rebuilt because, while the problem is most likely the speedometer portion of the cluster, the printed circuit or one of the resistors on the printed circuit may be fried, in which case putting a new speedometer assembly on will not solve the problem.

Is it on zero when it is turned off?
