non functioning odometer

I have a '91 Acclaim ( 2.5L ). The speedometer works fine, but the odometer quit working a couple weeks ago. I replaced the speed sensor and that made no difference. Anybody out there have any Ideas?:banghead:

If the speedometer works and the odometer does not , yoy will have to replace the speedo head .

Thanks sneakybert. I got another speedo head and that fixed it.:thumbsup:
