I searched and found another CEGer with the same problem. The solution is his case was to replace the alternator. For a while my lights were dimming at low idle while the speedo jumped up and down. That is not happening anymore. I do notice sometimes that my horn is weak and my power windows are slow to roll up. The car runs great otherwise for being 7 years old. I got 26.5 MPG on the highway today at 80MPH with the AC on! 200 miles on a half tank of gas! I do not get a charging lamp, but sometimes I can hear the engine whine/howl through the speakers with the radio on. I'm going under the hood this weekend to check things out. I'm hoping all this is due to a worn out battery (three years on it). I pray I don't have to replace the alternator! Gulp!
