Since both sides aren't working, we have to look at what they both have in common. That includes the 25-amp circuit breaker, and ground G304.
Start by checking for 12 volts on the orange wire at either switch assembly. If it's there, the best suspect is a corroded ground wire or terminal at G304. If the 12volts is missing, swap in a different circuit breaker as a first step. Let me know what you find.
