odometer not working on 1993 Mercury Grand Marquis

odometer is not moving is this a rather simple problem to correct and what is the cost of repair or replacement?

Asked by for the 1993 Mercury Grand Marquis
There was two different style instrument clusters for this model: digital and analog. With either of the two styles, the odometer is not serviced separately. The whole instrument cluster needs to be replaced. The replacement cluster needs to be pre-programmed with your current milage.
