MG5 LR rear screen heater not demisting completely

[Marma]

My current vans don't have rear windows so I don't think it will worry me.
Don't get me started on people that moan about the centre headrest in the way. Do you ask passengers to put there heads in there laps

I put all of my rear headrests in a box in the boot as usually there's only the 2 of us in the car.
Much better for rear view observation.
