Help! On the road with no turn signals

On vacation right now traveling. Have a test light along. No turn signals, but the flashers work.

'68 Dart. Friday I was in the Twin Cities while they received over an inch of rain an hour. Drove through alot of standing water. Turn signals still worked after that for about 3 hours and then nothing. I stopped at a parts store and bought a new flasher. No change.

There are the 2 terminals on the flasher. When the flasher is plugged in I have power at both terminals. When I probe the plug I have power at the 2 pink wires (same terminal) and nothing at the single red wire.

There was alot of moisture in the car on Friday. A few drips from under the dash when it was really pouring so something may have gotten wet.

Fuse? I don't see any markings that said turn signal on the fuse block. If the flashers work I am not thinking that it could possibly be a fuse. Am I wrong?

Any help would be great! Thanks for any ideas you can give me. I will be going through towns with parts stores today and can check in with my "smart" phone operated by a "dummy". :???:
