2003 Impala Headlights turn off without warning
About 3 weeks ago, one night the headlights went out while driving down the road. In a state of panic, turned on, pushed in all *****/switches and somehow the headlights came back on. Tonight as I was taking my son to karate, the same thing happened. This time pulled the headlight switch out and they came on, pushed the headlight switch back in and they stayed on like they were suppose to. 10 seconds later, they went off again. Could not get them to come back on this time. The fog lights and parking lights work. Does anyone have any suggestions as to what might be causing this?
