First off, the correct terminology is tachometer, not RPM gage. And second, we do not have enough information on your problem to give you a proper diagnosis, thus we can not tell you how to fix it. My suggestion would be to see a mechanic.
The RPM gauge is connected to the same wiring on as all the lights on the dashboard. A faulty RPM gauge can be replaced but requires removing the whole dash from the vehicle.
your rpm gauge works off your engin your speed gauge works off the transmission where the cable slides into the transmission tha plastic geer is probably stripped
Chack the fuse. If it's not the fuse, it's a sensor.

To fix the RPM gauge on a 2004 Kia Optima, first check the vehicle's fuse for the instrument cluster, as a blown fuse can cause the gauge to malfunction. If the fuse is intact, inspect the wiring and connections to the gauge for any damage or corrosion. If these steps don't resolve the issue, the problem may lie with the gauge itself or the vehicle's Engine Control Unit (ECU), requiring replacement of the gauge or professional diagnosis. Always consult the vehicle's service manual for specific troubleshooting steps.
When the radio in a Hyundai XG300 becomes all static, it is possible that the antenna is damaged. It could also be possible that the antenna is loose on the back of the radio.
could be a bad instrument cluster panel, they had a recall on the instrument cluster panel. I had my speedometer stop working and was given a price to fix it and blew it off. Then the recall came and I got a new instrument cluster and that fixed the problem which they knew they had.
The sensor (or the computer) is shot. Must be replaced to fix it.
To fix a non-functioning RPM gauge and speedometer, first check the vehicle's fuses related to the instrument cluster. If the fuses are intact, inspect the speed sensor and RPM sensor, as either could be faulty; replacing them may resolve the issue. Additionally, examine the wiring and connections for any damage or corrosion. If the problem persists, consider consulting a professional mechanic for further diagnosis.
A jumpy RPM gauge on a 1995 GMC Sonoma could be due to a faulty RPM sensor or a loose electrical connection. It can also indicate a problem with the engine such as misfiring or issues with the ignition system. It is recommended to have the vehicle inspected by a mechanic to diagnose and fix the issue.
Usually the cluster has failed. You will need a new one, or a used one that has the same mileage showing.
