Is their a simple check to see if the blend motors are operating ok. I have, to my knowledge no issue at present. If they do go faulty does it show as a defect on the screen.
Thanks Roger
On a long journey when I get bored I 'exercise' the blend motors by turning the temperature right up then right down and then gradually work along the various vent buttons. I figure that sticking with one standard setting will encourage the motors and the flaps they drive to stick as well.
