2009 Pontiac Vibe Headlights

The headlights and taillights do not work.
The are automatic and should turn on when
it gets dark but they don't. The switch is a 3 position switch that has off-parking lights and headlights.
In the off position the lights are supposed to come on in the dark automaticlly. The lights do work when you push the red emergency button on the key
and the horn beeps so I know they work. Other then that I can not get the lights to work any time.
