Stuck Odometer

[corey.sherman@rcn.com]

So driving along, minding my own business, when I noticed that the 
Odometer is stuck on 999...

I reset the Trip Odometer, with no results - still stuck.
Also, coincidently, my dash light when out.
This all happened when I decided to replace the firewall gasket since it 
worn torn ;-(
The Speedometer is fine (albeit, jump at times), but what happened. 
Next steps.

Thanks in Advance.
