Ours is a 93. Odometer display is cut in half unless you push on the screen. I took the unit out of the dash but can't see how to remove the odometer from the board. Was hoping for just a broken solder joint but can't see much with the yellow plastic shroud in place.
1. How'd you get the plastic shroud from around the odometer off the board?
2. Does the odometer unplug from your board?
I just don't want to mess things up beyond what they are since it sort of works now.
Thanks!

Not going to support a company that built this thing with guaranteed failure built in.
So i started making my own odometer with an arduino and as I was removing the old ODO and shield etc to
make room for the new stuff I saw the pin out hidden under the plastic mount see attached pic.
GND --- ODO
IGN --- Hours
Prog --- Pwr/Fail
VEE --- Sel/Res
-------- VEE
these are the same on the two connectors at the bottom center of the cluster.
So I figured this thing is dead anyway lets play.
I touched a jumper from prog to vee it put the ODO into programming mode.
The sel/res button cycled through the values just like setting an old clock the digit to be changed flashed.
I touched a jumper from odo to vee to advance the number.
On the last screen it came up with a number 1 if I left that I only had total miles displayed
I changed it to 2 and get total miles and one trip meter 3 gives total and hours.
Once I advanced past that screen it exits program mode and functions as normal.
I did this all on a bench with 12v and IGN powered from the back connectors.
I take no responsibility for any damage by someone trying this. I have no special knowledge of the internals other than what worked for me.
The Speedometer face does not need to be removed.
Hopefully this can save someone a headache.
