Disconnecting all of the electrical connectors that might have gotten wet is a good start. In Reno they should dry with a good wait, but I'd prefer compressed air to help them dry even faster. I'd say its almost impossible to see water inside the connector and when you disconnect them and look down into it the water drops further in. Compressed air will help chase it all out.
I agree you should assume its water before trying anything else.
