Volkswagen Golf / Golf GTI / Golf Variant. Manual — part 552
– The actuator mount -1- can only be installed in one position
on the actuating arm -2-.
• The actuator mount must be opposite the actuating arm as
shown in the illustration.
Note
If the mount and the actuating arm are not opposite each other,
turn the mount in the actuator.
– Switch on the ignition, connect the affected actuator to the ve‐
hicle wiring harness and select the setting for the desired
actuator position on the display control head (for example, the
center position). Wait until the actuator reaches the desired
position and switch the ignition off.
– Mount the actuator on the air distribution housing so that the
actuating arm reaches into the mount -1- -arrow-.
• There must not be any play in the connection between the
actuator and the actuating arm.
Note
If the bolts cannot be installed, the actuator does not sit com‐
pletely on the housing.
– Install the wiring harness so that it cannot come in contact with
any moving parts (for example, the lever on the actuator).
Note
Turn the actuator so far until it has reached a favorable position
for installation. The direction of rotation can be reversed by
switching the positive and negative.
– Check the Diagnostic Trouble Code (DTC) memory and erase
any displayed entries, then perform the “basic setting”. Refer
to Vehicle Diagnostic Tester in the “Guided Fault Finding”
function.
– Check the heater and Air Conditioning (A/C) unit function.
