lights flicker on concorde

My sisters concorde I think it is an 2000, she says all the lights flicker, dash dome, head, tail all. Been going since she got it new. It is intermitten and the dealer said they could not find a problem but she does not know what they did. I dont know how long they flicker either.

I just wanted to know if anyone else has/has this problem and if I could get some Ideas from people who know this car on where to look. It is odd all lights flicker, I would like to know if anything else happens at the same time, but being all of them should make tracing it easier, maybe, I hope.

I have a 1999, and occassionally the dash light , radio display will flicker,,, have not noticed the headlights or tail lights doing it,,, i just write it off and go on

I have a 99 Concorde and had the same problem with the lights flickering. That, I believe, was the start of some major electrical problems that we have been dealing with for over 2 years. First I had the occasional light flickering, then the interior lights would come on and stay on even with the ignition turned off and the key taken out (had to remove the fuse to get them to go off). After several trips to the dealer, they eventually replaced the body control module and wiring for the interior lights. That was last year. Two days ago, the same symptoms cropped up and the car died while we were driving down the interstate. The car is again in the shop and so far, they have no diagnosis.

I just had a similar experience. My 99 concorde died while driving down the highway. Cruise kicked off and we could not accelerate, so we pulled over. The car would not start Lights turned on by themselves and the power windows did not work properly. While waiting for AAA I tried to start the car and it worked. I took off and after about 5 miles the same thing happened again, this time cruise kicked on. I was wondering if you found out anything from your dealer. Do you have any other advice on something I could try? Thanks for any help!
