94 grand marquis odometer not working

I have 141000 miles on my GM. I just noticed that the odometer is no longer working. The trip works, speedometer works along with everything else. How do I fix this problem? Is it an expensive fix? Thanks in advance for any help!!

Sounds like the plastic gear sets gave out in the Instrument Panel. I would get a GOOD repair manual and remove the IP to replace BOTH the Odometer AND the Trip Odometer sets, since you are already in there. Here is a link to a company that sells them. They are supposed to be of high quality.. http://www.instrumentclusters.com/odometer-gear.html Let us know how you make out.....MB
