Odometer/tripometer stopped
 

OK, a while back, my tripometer quit working, but everything else was fine. Now my odometer has stopped working as well, but all other gauges including speedometer are fine. I was told my a friend to get a whole new cluster and have it replaced. Another says it might be a computer chip problem. I asked Ford over the phone, and they confused me, especially with the price. Any suggestions?
Thanks.
