I thought about fuses but there seemed to be too many different fuses involved. And I believe that the headlights aren't fused. The mix of items which don't work all seen to be controlled by the ignition switch so I'm currently leaning that way

I'm having intermittent electrical problems. Not working are Radio, Low beam headlights, parking lights, fan, power windows, wipers, seat heater light and possibly others. Working are speedometer, clock, gauges, turn signals, brake lights and Hi beam

Any ideas?
