The spec sheet for my 2010 sts, states that I have the rain sense, but if I do have it, it doesnt work. My car has the 1sc, y41. I have the lane departure warning, and the auto dimming headlights. So with all the electronics I have up around the mirror, and cant tell if I really have the rainsense or not. I want to take it to the dealer next week, but id like to make sure my car is really equipped with it. Can anyone describe the control module with all the other components around in that area. Ive tried every possible way to activate the rainsense but nothing works. Im assuming that its activated by having the wiper lever in the off position, and the intermittent switch up one notch. Thanks for any help.
