After a recent rainstorm, I lost power to my lights, including brake lights, the gauges and tachometer don't work, the rear interior light doesn't work nor do several dash warning lights.

I checked the fuses and found that several fuses are not being supplied with power. The lights work only if I use the switch.

Also there is a relay in the box behind the fuse box that is buzzing with the engine running.

I removed the under dash panel and carpeting on the drivers side to try to trace power from the ignition switch to the fuse panel but haven't found anything yet.

I found a post about a similar problem but no solutions.

This seems very strange, such a major power interruption should not be too hard to find but I'm not sure if I'm on the right track.

Any help is very much appreciated.
