dash lights on and speedometer not working
The instrument panel lamp of the car is on, which means it is powered on. The pointer does not rotate, indicating that the tachometer has not fully sensed. If the water temperature gauge and oil gauge are not displayed, the instrument panel is broken. If the speed cannot be raised, the speed sensor is broken. It is recommended to replace an instrument panel and check the tachometer at the same time to find the cause and then deal with it. The pointer of the instrument panel of the car does not move because the gear signal is lost. It will appear even after the battery is dead. You can go out of the 4S store to find after-sales personnel for maintenance.
