Sporadic Electrical Problems with dash board and fog lights

The dash board lights occasionally flicker, but have also gone out altogether. Sometimes it is the instrument cluster, once it was the heater control panel. As soon as I pressed the rear defroster light the heater control panel light came on instantly. This was at night. When dimming the instrument panel lights they flicker more times than when they are set to fully on.
The fog light issue may be different. I have to play quite a bit with the stick to get the fog lights to come on. The switch is at the end of the blinker switch, you pull it out to get the fog lights to turn on when on dims.
