Removing and installing right temperature flap control motorV159
Removing and installing right temperature flap control motor -V159-
  Note
t  The right temperature flap control motor -V159- is only fitted on vehicles with an air conditioner of the „Deluxe“ type.
t  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
–  Switch on the ignition.
–  Set the air outflow direction for the driver and front passenger side to the dash panel vents on the air conditioner operating and display unit, Climatronic control unit -J255-.
  Note
   
In the „air to dash panel vents“ setting, the right centre vent control motor -V111--B- moves the cam plate -A- to a position in which the bolt -C- is accessible. If the right centre vent control motor -V111--B- does not move the cam plate -A- to the required position, it may be necessary to remove the control motor → Chapter and move the cam plate by hand.
–  Move the front passenger's seat to the rearmost position.
–  Switch off the ignition.
–  Remove the air intake box → Chapter.
–  Mark the connector -D- (to prevent interchange with other connectors).
–  Unplug the connector -D-.
–  Remove the bolts -C- and -E-.

–  Release the pin -A- (at the holder of the control motor -C-) from the toothed segment -B- (of the temperature flap shaft) and remove the holder -C- (with the control motor) in arrow direction.
  A87-10468
–  Remove the bolts -A- and separate the control motor -B- from the holder -D-.
–  Detach the gear wheel -C- from the shaft -D- of the control motor.
Installing
Install in reverse order; paying attention to the following:
–  Attach the gear wheel -C- to the shaft -E- of the control motor -B-.
  Note
The control motor has no stop. The gear wheel -C- can thus be attached in any position to the shaft of the control motor.
  A87-10469
–  By turning in arrow direction, turn the toothed segment -B- (of the temperature flap shaft) as far as it will go into the position shown.
–  Insert the guide -D- (at the holder -C- with the control motor) in the mount -E- (at the air conditioning unit).
–  Slide the holder -C- in the direction opposite to the arrow towards the toothed segment -B- and insert the pin -A- (at the holder of the control motor) in the toothed segment -B- (of the temperature flap shaft).
  Note
The control motor and the gear wheel -C- have no stop. The gear wheel -C- and the toothed segment -B- (of the temperature flap shaft) can thus be assembled in any position.
  A87-10468
–  Fit the bolts -C- and -E-.
–  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.
