Removing and installing defroster flap control motorV107
Removing and installing defroster flap control motor -V107-
  Note
At present all the control motors on this vehicle are identical. During basic setting, control motor assignment and adaption are implemented on the basis of the arrangement in the series connection of the wiring. If the sequence is not as specified, the matching of the control motors and thus flap control will not be correct → Chapter „Block diagram of air conditioner control motors“.
Removing
–  Move the driver's seat to the rearmost position.
–  Switch off the ignition.
–  Remove the storage compartment beneath the dash panel on the driver side → General body repairs, interior; Rep. gr.70.
–  Remove the left (driver side) footwell vent → Chapter.
–  Remove the accelerator pedal module → Brake system; Rep. gr.46.
   
–  Mark the connector -D- (to prevent interchange if several connectors are simultaneously unplugged).
–  Unplug the connector -D-.
–  Remove the bolts -C-.
  Note
The bolts -C- can also be removed using the ratchet ring spanner -T40083-.
–  Unfasten the shaft -A- (at the control motor -B-) from the actuating arm -E- and remove the control motor.
Installing
Install in reverse order; paying attention to the following:
–  Check the position of the actuating arm -E- in the guide at the air conditioning unit -F- (pay attention to both stops -G-).
–  Insert the shaft -A- (at the control motor -B-) in the actuating arm -E-.
  Note
The control motor has no stop. The shaft -A- can thus be inserted in any position in the actuating arm -E-.
–  Fit the bolts -C-.
–  Plug in the connector -D-.
–  Lay the wiring harness such that it cannot come into contact with moving components (e.g. lever).
–  Re-install all the other parts removed in reverse order.
–  Switch on the ignition.
–  Perform air conditioner basic setting and final control diagnosis → "Guided fault-finding" function of vehicle diagnostic, testing and information system VAS 5051.
  Note
t  The control motors on this vehicle are equipped with electronics. A new control motor only learns its position at the air conditioning unit in the course of basic setting and can then be actuated by the air conditioner operating and display unit, Climatronic control unit -J255- (all control motors are identical at present) → "Guided fault-finding" function of vehicle diagnostic, testing and information system VAS 5051.
t  During basic setting, control motor assignment and adaption are implemented on the basis of the arrangement in the series connection of the wiring. If the sequence is not as specified, the matching of the control motors and thus flap control will not be correct → Chapter (block diagram of air conditioner control motors).
–  Interrogate the event recorder of the air conditioner operating and display unit, Climatronic control unit -J255- and erase any faults displayed → "Guided fault-finding" function of vehicle diagnostic, testing and information system VAS 5051.
