... after a couple hours of leaving open and drying everything out, turns and emergency flashers are working again.

However it did that once before without such intervention. Stop and start working I mean.

The only thing I can think of is that the first time it did this, the running of it with AC on, then the sitting in the Sunshine, got it dried out enough to work until the next time a situation occurred that put more water in, and sat through some heat a cool cycles to cause it to evaporate and then condense out.

I guess time will tell. All I can do is wait now.

I still have not located where the flasher is so would be welcome to some more specifics on the location
