A/C Unit

On removal, mark the various control motors and the associated connecting elements between door 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. Refer to => [ Air Distributor Housing ] Air Distributor Housing

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.

Apply a small amount of Grease (G 000 150) to the curved washer guides and the pins on the door levers.
