Neither rear door can be opened from the inside. I'm not sure when this occurred since we do not use the back for passengers very often. IIRC in normal use the button makes a 'click' sound. Nothing now. If it is a a setting, I could not find it. I have used the window lock setting before and I thought the door might be included but I changed the window lock setting to off and now the rear window controls work but the door button still does not. The door handles from the outside operate normally. I rebooted the screen with no effect. As an aside, I learned today that the rear doors do not have a manual open mechanism. Is there something simple I am missing here ?
