What is the reason for the Jetta dashboard lights not working?

[DelilahAnn]

The reason for the Jetta dashboard lights not working is either a damaged instrument cluster or a blown fuse. Indicator Lights: The most common indicator lights encountered while driving, such as lighting signal lights, turn signal lights, parking lights, etc., serve to indicate the status of various vehicle functions. Warning Lights: These have an alert function, such as the fuel indicator light, door status indicator light, seat belt indicator light, etc. Generally, warning lights turn off after the driver performs the corresponding action. For example, the seat belt indicator light turns off once the seat belt is fastened. Fault Indicator Lights: These are also the most important indicator lights, such as the generator fault indicator light, transmission fault indicator light, etc. These fault indicator lights rarely illuminate during normal operation, or they may light up briefly when starting the engine and then turn off. If a fault indicator light stays on continuously and is accompanied by a warning sound, it indicates that the vehicle has developed a fault or abnormality.
