did you have it verified that it is the cluster??
a shop with a scanner can check the cluster and manipulate all the guages and lights to verify they are working correctly.
i would check this first before replacing the cluster.
the cluster can either be sent out to be repaired, which means your car would be disabled for a period of time or get a new one for a lot more money.
the repaired unit would run about 350 plus 1 hour in labor.
the new unit is up around 600 or more depending on options with the same 1 hour in labor.
