Why would the temperature Gauge not work in a 2000 Daewoo Lanos?

The temperature gauge in a 2000 Daewoo Lanos may not work due to a faulty temperature sensor, which provides readings to the gauge. Additionally, there could be issues with the wiring or connections between the sensor and the gauge, leading to a lack of signal. A blown fuse or a malfunctioning gauge itself could also be potential causes. Checking these components systematically can help identify the issue.
