1998 Chevy Cavalier No lights

I would go out on a limb and say it is more than likely going to be your headlight switch, I had the same problem. My marker lights would come on and the only headlights I would have are my daytime running lamps. On occasion the head lights would come on but if you used your turn signal or hit a hard bump they would shut off back to the daytime running lamps. So I would give it a shot and replace the switch.
