One morning I found the CD changer constantly searching for a disk and the battery was nearly flat? The car was locked with the keys out. It has done it a few times. Also the rear window at times has been opening on its own when you start the car. When you shut it, it just clicks open again? If you turn the car off it will reset its self?
Has anyone had this before?
There are several fault codes relating to electronics and the rear window.
Thanks in advance?
