Removing and installing fresh air/recirculated air, air flow flap control motor -V425-, RHD vehicles

Installation is carried out in the reverse order. When installing, note the following:
  Note
Check operation of flaps and hinge mechanism before fitting.
Make sure levers and shafts are properly fitted in the mounts.
–  Fresh air flap must be set to “open” position, in order to allow fresh air to flow into the vehicle.
The operating shaft -2- must be on the stop -1--arrow- as shown.
  Note
If the control motor operating shaft is not on the “fresh air mode” stop, rotate the receptacle in the control motor.
–  Switch on ignition, connect respective control motor to vehicle wiring harness and select a setting on operating and display unit to set control motor to desired position (e.g. mid-position). Wait until control motor has moved to desired position and switch off ignition.
–  Position the control motor on the air intake box. The operating shaft must engage in the receptacle.
There must not be any play in the connection between the operating shaft and receptacle.
  Note
If the bolts cannot be fitted, the control motor is not completely seated on the housing.
–  Route wiring harness so that it cannot come into contact with any moving parts (e.g. actuating arm on control motor).
–  Read event memory, and clear any entries displayed. Then, perform “basic setting”vehicle diagnostic tester in “Guided fault finding” mode.
–  As a final step, check operation of heater and air conditioning system.
