Look online . There are different companies that sell the parts to replace the gears.

    We looked online and only found 2 places and these were both way too high to buy those gears from. We will look in junk yards instead of buying them from these sites.

The odometer stopped working.The speedometer works but not the odometer or the trip meter.

inside the cluster is a min-computer that controls both of these

therefore, assuming you do not have a wire loose then it appears you will need a new cluster assembly

Speedometer works but odometer doesn't on 1992 Grand Marquis. what could it be

There are two plastic gears that drive the odometers from two small electric motors (one for resettable and one for total) and they wear out. I found them on the web for approx. $70 (for $0.50 worth of parts !), but they did fix the problem. You will need to remove the instrument panel and disassemble the odometers, but it's not too difficult.

Odometer stuck speedometer works ok 1992 mercury grand marquis

The only fix is to replace the speedo head. I had a 92 crown vic (same as marquis) and the speeometer shop could not repair it. So, i had to replace it. They give you a sticker to write the present mileage down for reference,and afix it to the drivers door jam.

1992 Mercury Grand Marquis - The odometer stopped working. The problem was traced to the instrument panel. The dealer will only replace the whole instrument panel except they can't get one for that car....

Go to a auto recycler or ..... you have to remove the woodgrain trim panels and the radio ... then the bezel ... a string that attaches to the steering column to the gearshift selector in the gauges then the guages ...

The trip odometer does not work.

Your problem is within the odometer its self. I would check with a local parts house to see if they deal with a speedometer repair business. Then the unit can be removed and sent out for repair, saving you the cost of buying a new one.

Odometer gears

it isnt easy!,the whole unit is peened,and factory assembled,it's built to be non-servicable,get another unit from a junk yard,I have fixed many,and it's a LOT of work!!. in your case it may be simple as replacing the "drive shaft"(it has a worm gear on it).
good luck!!
