Headlights flickering - 2006 Charger

    The headlights and dashlights on my daughter's 2006 Charger have started to flicker in the past few days. Not all the time but seems to happening more often in the last day or so. What should I be looking for? The battery is less than 6 months old and the car has about 90,000 miles on it (3.5l). This is Chicago so the temps have fluctuated between 0 and 40 degrees in the past few days. After she first noted it, I drove the car and did not have any issues during a 1-2 mile drive.

    Thanks in advance,

    Gerry G.

    Bad grounds? Even maybe bad/loose filaments in the headlight bulbs?

    Alternator? That would be my first guess.

    Does it seem to be affected by going over bumps or not?
    Does playing with the headlamp or hi-beam switch change anything at all?
    The TIPM/FCM (totally integrated power module/front control module) powers the headlamps and there may not be a fuse or relay.
    The modules can also store fault codes related to lighting, so if one is present it may give you a place to start. You may need an advanced scan tool to read these codes.
    See chapter 8L for lighting and 8W for wiring colors/diagrams here (large 212mb file):

    If there seems to be no pattern, my guess is the headlight switch.

    I had a similar problem on my 2005 300c. It turned out to be the headlight switch. On my 300 I found that if I disconnected the switch all together and started the car, it turned on the headlights by default. They did not flicker while I had the switch disconnected so that pointed towards an issue with the switch. I replaced it with one from Rock Auto and have not had a problem since.

    Or just a loose plug at the switch. If you just unplug and replace the switch and plug in, you might not realize that it could be a loose plug, and end up blaming the switch. In my experience, intermittent connections are more frequent than component failure.

    I'd bet on a loose and/or corroded negative battery cable connector at the battery post.

    I can confirm that if you do unplug the headlight switch on these cars the lights do come on by default. That is a good test to see if it is the switch.

    Many models have problems with the multi-function stalk switches. Take one apart, its very complicated inside with lots of different contacts, etc, to be able to switch a dozen different things from moving levers in multiple directions and switches that are mounted on moving parts, etc. Stuff inside fails and makes intermittent contact, etc. I'm sure RockAuto will tell you, they sell a lot of multi-function stalk switches for many different makes and models.

    The headlight switch on these cars is dash mounted. Only the dimmer is controlled via the stalk.

    Thanks for all of your input.

    I am suspecting the switch itself. I was able to see the issue in action. It is not a flicker, the headlamps go out. Interesting part, I can flip the switch to off and the headlamps come back on, for a while. They will go out in a bit and flipping the switch back to on will turn them back on most of the time. Sometimes the dash lights will go out with the headlamps, other times they will stay on as if in the parking lamp position. Did not look at the parking lights as I was moving at the time. There were times the headlamps did not come on in any of the switch positions. Did not seem to be related at all to speed or road bumps.

    I will keep you posted.

    Thanks again,

    Gerry G.

    Replaced the headlamp switch. That seemed to be the problem. Took a nice long test drive and the headlamps stayed on. When I was removing the switch and popped it out of the dash, the headlamp on ding went off which kind of confirmed the suspicion since I did not move the switch at all.

    Thanks much for all of your suggestions.

    I NEED HELP!!! i have the same issue and replaced the headlight switch and my lights still flicker. When I unplug the switch my lights work perfectly whenever my car is on. Everything points to a bad headlight switch but installing a new one did nothing. I'm baffled

    Where did you buy the new one? I had the same problem with the base 1-year warranty switch at O'Reilly's; when I exchanged it, the replacement was also bad. The next time I exchanged it, they upgraded me to a lifetime one at no extra charge, and it's been working fine since. The base switches were made in China; the lifetime one was made in Taiwan. I'd avoid Chinese-made electric parts.
