90 New Yorker Odometer Problem

Feb 15, 2004 4 Replies

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.

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. Steve

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 :)
