Odometer not working but speedometer does

[Lybmeanit]

I replaced the entire cluster and the odometer still doesn't work any suggestions?

Welcome to TRS

Electronic speedometer/odometer setup is the same as older cable driven, both share the same signal, spinning cable or electronic pulse.

So problem was/is in the cluster itself if speedometer works and odometer doesn't, or visa versa.

The plastic worm gear that drives the odometer was a know issue with that vintage instrument cluster.

Thanks it was the worm gear

The worm gear was broken on the one and the little motor looking thing was bad on the other . I used good gear and motor and it's working.
