I was driving my 2004 Spectra EX when I noticed that the clock on the dash was dim. Shortly (about 2 minutes) after the speedometer started fluctuating wildly and the radio died, then the speedometer just stopped working. Next the rest of the instrument cluster stopped working lights and all. Then the engine died at a stop light. When ever we try to start it, it just makes a fast paced clicking sound. The head lights, windows, and locks seem to work okay, but the instrument cluster is sporadic and there is a constant buzzing noise coming from the dash even when the key isn't in the ignition. Any ideas??
