Oldsmobile/Buick Repair: Odometer not working?, salvage yard, buick century

Question
I have a 1991 Buick Century Custom with auto trans I believe is M9. It has a 3.3L engine. My speedometer works fine but my Odometer and the trip odometer do not work. Could that be the speed sensor or is it something else?

Answer
Hi
It is the cluster itself. The Odometer works off the speedo head, so if the speedo is working then the cluster is at fault.
You MAY want to try getting one from a salvage yard in your area, finding one with the approxomite mileage.
Other choice is to remove cluster and take it to a dealership for them to send off and have repaired.
Or call your local dealership...there may be a repair facility in your area (there is not in mine).
I Hope this helps.
Good Luck
