I have no power on the 4 button panel under the gauges That operate the Lights, Wipers, Washer and Buzzer Silent functions. It seems as though there just is no power to the panel. I'm not sure where power is supplied from. I've got the panel somewhat torn apart but came up empty on getting voltages. I haven't give up on it and will keep poking around and trying to sort it, just figured I'd ask here as well. On the diagram it is labeled "Panel Switch 1"
I traced it down to a corroded wire that had broken inside a harness connector under the switch panels. I jumped a wire passed the connector and it all came to life. Now I just need to wire up my lights.
