I changed my battery and everything was finally restored in the car. Ex. windows, steering light. I have noticed that the led diodes on a few displays don't completely light up. For instance the outside temp display shows only parts of the first no. or the mileage readout is missing parts of other numbers. It's not always the same ones every time you start the car and sometimes they all work except for the the final digit on the mileage readout. Any help?
