The temperature gauge on a Mazda3 may malfunction due to various causes. If you observe other components of the display behaving abnormally, it's probably a fuse problem. However, if only the temperature gauge is faulty, it likely indicates a problem with the vehicle's thermostat. Replacing the thermostat typically ranges from $10 to $30. Opting for professional installation can increase the total expense to around $200.
Typically, when the temperature display on your Mazda 3 is not functioning, the issue is often related to a faulty sensor.
