Depends.
Older cars used mechanical odos, which do rely on gears. Modern cars, it's all electronic
I have pulled apart Four (4) differect Speedometers in which the odometers did not work. ALL of them had the inside RED gear basically disintegrated. Just remove the odometer 2 screws. Then remove the stepper motor, 2 screws. There you will see it (inside a white gear) disintegrated. I will probably be manufacturing the gear & rebuilding the odometer. Yes you quessed it, making a new gear ! YUK !
There is not any fuse on any car that will disABLE THE ODOMETER. I
excessive gear lash.
To fix the non-working odometer in your 1992 Dodge Dynasty, first check the speedometer cable for any damage or disconnection, as a faulty cable can prevent the odometer from functioning. If the cable is intact, inspect the speedometer itself for any internal issues or wear. Additionally, you may need to remove the instrument cluster to access and repair or replace the odometer gear, which can wear out over time. If you're not comfortable with these repairs, it's advisable to consult a mechanic for assistance.
It is against the law to tamper with any odometer.
First of all make sure the cable is connected to the transmission housing. If that doesn't do it, check to make sure you have the right gear inside the cable housing that connects to the transmission. Make sure your cable isn't defected. If you have any questions email me at victor1gray@yahoo.com.
I have a 95 Lumina 3.1 and it would cut out of gear when I would stop, it turned out to be the sprag gear in the transmission. $$$$
To fix a non-working odometer on a 1994 Honda Accord, first check the speedometer cable for any damage or disconnection, as a faulty cable can prevent the odometer from functioning. If the cable is intact, inspect the instrument cluster for any signs of damage or malfunction, and consider removing it to examine the gears and connections inside. Additionally, the issue might stem from a faulty odometer gear, which may need to be replaced. If you're not comfortable with these repairs, it's advisable to consult a professional mechanic.
Bad transmission? Bad Clutch?
could be the clutch is worn or needs adjusting
The gear in the odometer head gets dry rotten and teeth break. To my knowledge, no one has any parts to fix it. That is actually why I am answering this question. Even salvage yards have broken odometers. Dealer says discontinued. I need help fixing mine.
It is illegal to disconnect the odometer on any vehicle. So you will get no help here.
