This has never happened to me but i see that in the 3rd gen fAQ thread:
https://www.rx7club.com/3rd-generation-specific-1993-2002-16/faq-3rd-gen-other-useful-links-68640/

There is a thread for odometer repair under the O section:
https://www.rx7club.com/showthread.p...light=odometer

If that doesn't help, go to Search and click Advanced Search and search the 3rd gen section on 'odometer'

Good luck

 

Replace your dimmer switch! its about $150 brand new. I spent days going through the diagram trying to troubleshoot it.
