Mine is doing the same thing. At first I thought that it did not display at all, but today when I started the car it showed -36F until the buzzer turned off. Obviously this is not the correct temperature, but it means that the LCD is good. How can I find the temperature sensor? I don't understand how you people can trace these things - I look under the hood and there are so many wires and tubes going everywhere I can't figure out what is coming from where.
