John, I had the same problem on my 2002tii, except my odometers worked on 
and off. They would usually freeze after trip odometer reset. 
Speedometer worked OK all the time. As for the tach, it is a purely 
electrical device - totally independent from the drivetrain driven 
speedo-odo.

The bottom line is the problem is in the speedohead (I take it odometers 
are mechanical - not digital). The head receives torque via a tranny 
driven cable. The fact that your speedo is working suggests that this part 
is functioning OK.  

I had a worm gear that "ate" away a piece of the plastic gear it was 
supposed to turn! My guess is you have broken or disattached gears. A 
self-repair may, or may not be possible in case you need replacemnt parts. 

Tp make it short, I replaced my speedo head with one from a wreckyard - 
make sure the final drive ratio is the same like on your car.


cheers!
