It is placed on the dashboard and it shows the "engine spins", that is to say, the rotation speed of the engine. It varies depending on how much the driver is pressing on the accelerator, no matter whether the car is moving or not. Through the transmission, the acceleration will be linked to the wheels, and this will allow the car to advance.
The same issue happened to me, I didnt have a jump or anything. It was working the night before and the next morning the display was completely blacked out the only thing that works is the transmission sign when you turn the ignition. The radio works fine, any suggestions on how to fix it????
Please help
