I'd try to trace the wires from the panel and check the connections at each step along the circuit. Be aware of the dangers of working with electricity. Sometimes you will uncover important things that need attention or were done poorly that you can fix. Other times understanding that was done can be more complicated to unravel (particularly if there are inaccessible ★★★★★★★★ boxes), but you can at least be aware of the possible consequences. Switches that don't work properly, or wires that are not the correct polarity, are an indication that something needs to be addressed.
