You didn't say what year it was so it could be any thing from old school speedo driven gear, speedo drive gear, speedometer cable, speedometer head, to newer VSS, speedometer servo motor, speedometer head or computer issues.
How do you expect to get a good answer without a good question. It's like asking how much to fix a blue thing.
Not sure why speedometer not working ,is the repairs expensive?
