Both headlights unexpectedly turn off while driving. Flicker on and off and then go off. Used to be able to let the car sit a few hours and they would work again. Now 2 nights ago they went off while driving at night. . . . Won't come back on at all. Parking lights stay on, turn signals, and 4 way flashers still work, pull switch lever back for bright lights and both headlights work in bright mode as long as you keep holding back on the lever. This was an intermittent problem that no one has been able to figure out. Have had it looked at several times and problem still exists. Replaced hazard flashers swithc, replaced mutlifunction switch, replaced headlights switch. Problem still exists. Now lights are off and won't come back on no matter what we try. . . . . Looking on the internet this is huge problem for Impala's covering alot of years, this is a very dangerous issue when you loose your headlights totally at night while driving. . . . . . . Once they go out/off it doesn't matter if you stop, park, move, bang on them, wiggle wires and connectors, they may or may not come back on. So far, this time, ours are not coming back on. . . . . . Can't keep throwing money away to a dealer when they can't fix the problem either. They just want to start throwing parts at it and hopefully they finally fix it. . . . That hasn't worked so far either. . . . .
2001 chevy Impala headlights went out on our way home from the fire works on July 4th. Lucky the cop stopped us at the corner while directing traffic. The multiswitch has gone out.
Headlight dimmer switch caught on fire and burned wiring.
