Heating And A/C Unit, Disassembling And Assembling

NOTE:
- On removal, mark the various control motors and the associated connecting elements between flap and motor to prevent mix-ups with connecting elements of other control motors.
- When removing, mark various connectors to actuators and actuators themselves (risk of interchange with identical connectors and actuators).
- If connecting elements are interchanged, actuators with incorrect connecting elements do not reach their specified end position, and fault "upper or lower limit exceeded" may be displayed in DTC memory after basic setting.
- Levers and cam disks are provided with code numbers. In case of doubt about assignment of one of these components, observe assignment
- At present, actuators are identical, the shaft of each motor however is positioned differently because of different connecting elements and attachment of connecting element may not be possible if interchanged.
- Lightly coat guides of cam disks as well as lugs on levers of flap with grease G 000 150.
