I believe the fuses for the lights are inside down at the floor near the steering column. If the fuse is good I would check the ground wire connection back to the frame. My headlights and fog lights would not work one morning and after tracing it out I found the ground wire connected to the frame with a trim screw through a washer and a terminal round connector. The screw had coroded and the paint on the frame was never removed to allow a good contact, so the threads of the screw provided the connection. I drilled the hole out and wire wheeled the paint off and made the connection with a bolt. I then sprayed battery terminal protector on the connection. If you look behind the mass of wire by the firewall on the driver's side the ground attaches to the frame behind the wires. I cut a couple of the wireties so I could move the wires out of the way. Afterwards I rebundled the wire with a little heavier duty cable ties. Good luck and let us know what you find.
