Blend Motor Check

Hi to all

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

If the temp changes and the distribution changes they work....

Usually if they feck up, you will get the Testbook symbol on the HEVAC display

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.
