my rear window sometimes takes a little longer to start clearing, it only does this when i also have the heated front window & all the lights on etc but i am only talking about a minute extra and so far i have always switched off the rear screen before it has ever timed out on its own ( even when iced up on the outside & not just a foggy interior )
it might be worth unplugging the wires on the wingmirrors as this may help if there is a lack of power getting to the rear screen.
might also be worth unplugging the wires from the screen itself and making sure they are making a nice clean contact :L
