How are gauges, power windows, and turn signals related electrically?

This morning, I started the car and noticed the fuel and temp gauges intermittently flicking between showing a reading and zero. When they were at zero, the power windows also didn't work, neither did the turn signals. The HVAC blower and headlights worked fine the whole time. I re-seated all of the fuses, and that seemed to fix the problem. Since all of those accessories are on different fuses, and it's unlikely that multiple fuses would lose contact at once, which single fuse being loose would cause those symptoms? Does one of the fuses control a relay that in turn controls other things?

Car is an '83 240D.
