tunnel. ⇒ General body repairs, interior; Rep. gr. 68
– Use 2 screwdrivers for example to carefully prise the connect‐
ing element -C- off the control motor.
– Mark the connector -B- to the control motor (to prevent inter‐
change with other identical connectors).
– Unplug the connector -B- from the control motor.
– Screw out the bolts -A-.
– Detach the control motor.
Installing
Install in reverse order, paying attention to the following.
– Moisten the guide of the lever -C- or the lug at the flap lever
with a small quantity of lubricating paste -G 000 150- for ex‐
ample ⇒ Electronic parts catalogue .
– Attach the connecting element -A- to the control motor shaft.
Note
Check the positioning of the connecting element. It must en‐
♦
gage in the shaft of the motor and there must not be any
clearance between the control motor shaft and the connecting
element.
The connecting element is only to be attached in the position
♦
in which it engages without having to exert force. If pre-tension
is required to insert the connecting element, 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 connecting element -A- attached.
The motor may be incorrectly positioned if pre-tension is re‐
♦
quired to insert the connecting piece -A- in the control motor.
If the shaft is so awkwardly positioned that the connecting
♦
piece cannot be attached, use an adapter cable for example
⇒ page 47 or a test lead from the adapter set -V.A.G 1594/ A-
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.
– Re-install the 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.
