Attempting DIY repairs is extremely risky and will likely result in further damage or a completely non-functional instrument cluster. Tampering with the odometer is also illegal in most places as it's considered odometer fraud.
If your Sebring's odometer is malfunctioning:
1. Check the fuses: Start with the simplest solution. Check your owner's manual to locate and inspect the fuses related to the instrument cluster. A blown fuse could be the cause.
2. Professional repair: Take your vehicle to a qualified mechanic or a specialist in automotive electrical systems. They have the tools and expertise to diagnose the problem and potentially repair the instrument cluster or replace it. A reputable shop might be able to repair the cluster, but replacing the entire unit is often more cost-effective.
3. Used replacement: You could find a used instrument cluster from a salvage yard or online parts supplier. Make sure the mileage is reasonably close to yours, or you'll face legal repercussions if you use it to alter your odometer reading. Note that even used parts will need to be professionally installed and potentially programmed to match your vehicle.
In short: Don't attempt to repair the digital odometer yourself. Professional help is your best option.
