1. You really may have a light out somewhere on the car.
2. With all the little flakey sounding things, your battery may be the whole problem, maybe not.... this car does wierd stuff if the voltage or current are not right.... change the battery and then see what you have.
Oh.... check ALL of the lights on the car..headlights, tail lights, side markers, map light, glove box, license plate and any that I missed....
