rain

I know there are threads on this subject but none that I have found directly answer the question, how do you know if you have rain sensors on the CT? Is there some icons on the control for the normal windshield wipers? I know, stupid question.

I have the feeling that both light and rain sensors are buggy. I got out of my garage 9 o'clock in the morning on a fully sunny day and lights didn't went off even 10 minutes later. I switch them off and put them back to auto and they stayed off... This is not the only incident of course, but...
