I turned the lights on the other night, and the two headlights and one passenger side tailight came on. Neither the driver side tailight nor the instrument cluster nor the switches lit up. Backseat reading light comes on, door lights work, trunk light works, license plate lights work. I checked the fuse 3 which controls this and it is fine. Im lost here. Does anyone know what this can be?

thanks
