If the headlights stay on one beam, the high beam will not come on, or the lights flicker when you switch beams, the dimmer switch can be one cause. With the engine off, look over the switch and its connector for cracks, melted plastic or loose terminals before replacing it, because a bulb or the wiring can produce these symptoms too.
