How do you keep your headlights and fog lights on at the same time on a 2000 Buick Regal LSE?

There is a switch especially for the foglights under the dash towards the driver's side door left of the steering wheel. The foglights will come on only if the low beams or the park lights are on. When you change from low beams to high beams the foglights will go off. Also when you turn the car off the fog lights go off too.
