    Windscreen demister motor

    Hey guys
    been looking at buying a a4 2.0 tfsi 2005 off a friend of mine. Trouble is none of the motors that control the airflow to upper ,middle and footwell vents appear to work. The green lever one( windscreen demister moves a little but not much) Have tried all combos on the controls. A mechanic friend of mine has said the problem may be the body control module. Does this sound about right and how much would it be to fix approx.

    Many thanks

    Take the motor out. Take them apart grease the worm drive gears. Put back together. Put them back in and reset with badic settings with VCDS.
    Then see if they work.

    Ta for the quick reply. Have already taken green levered one apart and done that. Only get small movement on it . Almost like motor I sent strong enough to move it thru its full range. Nothing from other two motors. In fact selecting footwell vents caused a little movement in the demister( green) lever!!!!!. This was why friend suggested body control module.
    Also what is badic and VCDS

    Cheers
