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.
