Headlights, Tail lights, Side Markers, Help needed.

Thanks so much for all of the advice. It was indeed the A4 fuse. Lights are now working great.

Why is there only one Rear Fog light on the drivers side and not one on the left rear? This is not very symmetrical. I saw on a wiring diagram that there was no fog light for the rear passenger side and also saw in this thread a post to that effect. There is a bulb spot for one though.
