The right side view mirror is supposed to dip when backing, it offers better view of curbs and objects close behind you. You may be able to turn it off if you prefer, mine is programmable, read the owners manual. The seat switch can be easily repaired if you are so inclined. Get a can of electriconics cleaner from Radio Shack. It is better if you remove the switch and open the face, then just spray on the cleaner, wipe it off and you will be good to go. The AC uses partial heat/cooled air to maintain temperature, I don't know what would cause it to malfunction after 2 hours.

Best,
