THE following DO NOT light on:

The dash lights (speedometer, tach, and other guages), all the front vents, all the climate control buttons, the radio lights, the window switches by the shifter, (the shifter light burned out 2 years ago, so I don't know about that one, but I suspect that would be out too), and the rear window switches, the sunroof switch, and the headlight switch lights..
