– Attach the cam plate -A- to the control motor shaft.
Note
Check the positioning of the cam plate. It must engage in the
♦
shaft of the motor and there must not be any clearance be‐
tween the control motor shaft and the cam plate.
The cam plate is only to be attached in the position in which it
♦
engages without having to exert force. If pre-tension is re‐
quired to insert the cam plate, check the mount of the motor
as this may be turned through 180°.
The control motor shaft -B- has no stop. It rotates constantly
♦
if voltage is applied between contacts 5 and 6. When the con‐
trol motor has been detached, voltage is therefore only to be
applied with the cam plate -A- attached.
The motor may be incorrectly positioned if pre-tension is re‐
♦
quired to insert the cam plate -A- in the control motor.
If the shaft is so awkwardly positioned that the cam plate can‐
♦
not be attached, use an adapter cable for example
⇒ page 47 or a test lead from the adapter set -V.A.G 1594/C-
to connect contacts 5 and 6 of the control motor by way of a 5
A fuse to a 12 V battery.
Turn the control motor until no pre-tension is required to attach
♦
the connecting element. The direction of rotation can be re‐
versed by interchanging positive and negative.
– Moisten the guides of the cam plate -C- and the lugs at the
levers of the flaps -A- and -B- with a small quantity of lubricat‐
ing paste -G 000 150- for example ⇒ Electronic parts cata‐
logue .
– Move the levers -A- and -B- of the flaps to the position shown.
– Insert the lugs of the levers as shown in the guides of the cam
plate -C-.
– Attach the control motor to the air conditioning unit.
– Use an adapter cable
tacts 5 and 6 of the control motor to a 12 V battery by way of
a 5 A fuse.
– Turn the control motor until it reaches the end stop, then in‐
terchange positive and negative at the control motor and move
the control motor to the other end stop.
– Re-install the other components removed in reverse order.
– Interrogate the fault memory of the front operating and display
unit, Climatronic control unit -J255- and erase any faults dis‐
played ⇒ "Guided fault-finding" function of vehicle diagnostic,
testing and information system VAS 5051.
– Perform air conditioner basic setting and final control diagno‐
sis ⇒ "Guided fault-finding" function of vehicle diagnostic,
testing and information system VAS 5051.
