97 Wrangler top down in rain 2 months later turn signal flasher ticks non-stop replaced no help. How do I stop the ticking?

I had the same problem and it is a very common one in most jeep owners. Simply crawl under the dash and disconnect the relay for the turn signals. It is a black box, about 2"x2" mounted under the steering column just to the left. Of course you will need a new one which is not an expensive replacement, and well worth it if you ever want to get rid of that annoying rapid clicking. Also check the wiring in the rest of the instrument panel with a volt meter as other problems can arise when they get wet.
