FYI....had the issue of the top not going down last year. After spending $400 for my "master mechanic" to change one of the sensors in the front of the top, it still didn't work. They wanted another 270 to change another one. Well...knowing there is a sensor in the back, when you pull up your divider, I thought maybe, it wasn't having enough contact when I snap the arm into the latch where the sensor is. I put a small piece of duct tape around the left arm of the divider so that when you snap it in, it's really tight. Not an issue since then. Always goes up...always goes down. So happy I wasted $400 on nothing...
