It sounded like the AC panel is having an issue. I had this happened to me before. Back and forth with the dealership several times, they couldn't reproduce the problem. Finally, one of the master technicians was able to figure it out. Every time, he pressed his finger on the AC panel around the knob, the whole system went crazy. A new AC panel costs around $850. This job takes about 2-3 hours. It was fixed on mine under manufacturer warranty -- free.
