I have a 2002 Chrysler Concorde Lxi 3.5L V6. During the day, the lights on the dash will flicker to dim brightness occasionally. At night, when this is far more annoying, the lights will occasionally flicker to high brightness. It's just a quick flicker lasting only about a second or so, they don't stay stuck at the wrong brightness.
The car is equipped with an automatic sensor somewhere that determines when to turn on the headlights and dim the dash lights.
The only electrical modification I've had done to this car was to have a remote starter installed. I want to say I've had this problem since about that time, but I can't say for absolute certain.
If anybody has a good idea what may be causing this problem, let me know.
Thanks, PaulH
