Cockpit Lighting will not come on

[crazy diver]

2001 380 AC, cockpit lighting will not turn on (5 lights). There are 3 switches in the cockpit and 1 in the salon for the cockpit lighting. I changed the switch in the salon hoping that was problem, but it did not help. I cannot find a dedicated breaker for this circuit. Does anyone know of a another switch that might have got turned off. Any suggestions on getting these to work again would be appreciated.
