Hi there, thanks for writing in. I’d be happy to help. This may be related to the instrument cluster itself or potentially related to the connection behind the dash.

If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make any repairs as needed.
