Just a follow up spent today fitting a p3 brake controller to my kluger and whilst removing the passengers side dash guess what I found a button that is in the glove box that disables the rear power door. I feel like a goose but a least my rear door works. Have fitted the controller in where the coin drawer. This is the second time I have fitted it there as you don't hit your knee on it. Hope this is helpful for any one else who doesn't no why the door works.
