90 New Yorker Odometer Problem

Dear Group,

I have a 90 New Yorker 3.3L where the odometer has stopped counting
miles. The speedometer works just fine, however. I was wondering where I
should start looking to diagnose the problem. I am assuming that since the
speedo works (albeit it's 5 mph off.. always has been) and the odometer
doesn't, that the problem is internal to the Unit and not electrical. This
happened after resetting the trip odometer, which also tells me that there
is a mechanical problem in the unit, but I would like the opinion of the
group before I go pulling my dash apart. Also, if I need to replace the
unit, what do you think the probability of finding a used unit would be?

Thanks all for reading this...your input is greatly appreciated..

replace the AT with @ and DOT with . and remove all {{ }}and (( ))for my
email address. Thanks!

 

Actually, the odometer is driven by a small electric motor mounted on the
speedometer circuit board.

Maybe and maybe not -- the trip odometer is driven by a geartrain off the
main odometer. Same motor runs 'em both. Pushing the trip reset button
disengages the trip odo from the geartrain and allows its spring loading
to carry the drums back to 000.0.

How good are the yards in your area? If they suck, hit www.car-part.com
(searchable used auto parts nationwide). Pick up a spare IP and you'll
have plenty of spare parts to make it work again.

Is this a mechanical or electronic unit ?

If electronic I would suspect the last switches you pushed is failing like the one that
switches the odometer to trip mileage.

Thank you for the information. Now I am wondering if there is any way to
test the odometer motor, or should I just scrap it..

Thanks, Daniel!

It's a mechanical (analog) unit.. not digital.

Thanks for your input
