Our recent stretch of several days with precipitation ended and I was able to drive the car with the top down today.
I locked the car with the top down and the horn didn't sound. When I put the top up and locked the car the horn sounded twice. This suggests that I should focus on the top microswitch and associated wiring as the first area of exploration.
