Dash lights flicker from high to low brighness

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,

That problem is very common and is affectionately referred to on the
various LH car forums as "the light show". General fix or workaround is
to move the dimmer wheel to a different position. Sometimes moving the
wheel back and forth over its range a few times will fix it too (cleans
the wiper). Last resort: Replace the headlight/dimmer switch.

As Bill said possibly the headlamp switch, a common problem. But make sure
the battery terminals aren't corroded and rusted up, as this will cause the
same problem.

I replaced the dimmer wheel and I haven't seen the problem since.
Thanks!

 

You're welcome!
