The problem with mine was a small (blue) gear driven by a motor in the speedo cluster. the gear had a few stripped teeth which caused the odo to stop working.
The problem I have is that to get repaired I have to take to a instrument repairer who won't sell me the part (and will charge me $125 Aussie dollars to fix.
The gear is plastic and worth about 20 cents.

you have to get anew speedometer,speedy bo peep.
Sorry, it can't be done. You have to change the whole unit because the odometer is tamperproof. Check with your Nissan dealer to see what your options are.
In a 1990 the speedometer is electronic, but the odometer is gear driven. These gears fail frequently. I would suggest visiting the IPD website. They have the gear along with an instructional DVD to help the process.

Nine times out of ten the easiest and cheapest way to fix this is replace it with a working one from the wreckers. Are you sure it doesn't have child lock on?
