If the odometer is not working but the speedometer is still indicating speed, the most likely fault is a set of small plastic gears inside the speedometer instrument itself. I have seen these gears available for sale at various BMW parts specialists. Removing the dash cluster for access to the speedometer is not difficult in a 1987 E30 car. With the cluster on the bench, you can repair the speedometer gears or replace the whole thing. Used speedometers are plentiful at on-line auction sites such as eBay.
The odometer has failed
my odometer on 2002 volvo s-80 does not work
If the speedometer and odometer are both not working, I would blame the speed sensor. If only the speedometer does not work and the odometer does work, the cluster is bad.
probably need to replace the speedometer cable. if turbo check the big one that goes along the firewall possibly got burnt up on the down pipe
If the speedometer works but the odometer does not, the odometer has failed.
Sounds like a loose electrical connection, possibly a loose ground.
why would a speedometer and odometer not work on a suzuki motorcycle?
The odometer is broken and needs replaced.
My speedometer works and the odometer does not because there is a plastic gear in the odometer that is broken.
there are no light in odometer to see milege and clock
The gears in the speedometer are stripped. If the odometer is working then you have input.
odometer won't work w/o speedometer working
