– Attach the connecting element -A- to the control motor shaft.
Perform further installation operations in the reverse order of re‐
moval.
Note
Check the positioning of the connecting element. It must en‐
♦
gage in the mount of the motor and there must not be any
clearance between the control motor mount and the connect‐
ing element.
Pay attention to correct assignment of the connecting element
♦
(„red" colour for left control motor and „blue" colour for right
control motor).
The connecting piece 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 piece, 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/C-
to connect contacts 5 and 6 of the control motor by way of a 5
A fuse to a 12 V battery.
In the event of the fault „Upper or lower limit value exceeded",
♦
check the motor/flap connecting element. It must be properly
attached to the motor and there must not be any clearance
between the control motor mount and the connecting element.
Turn the control motor until no pre-tension is required to attach
♦
the intermediate piece. 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 basic setting and final control diagnosis for the air
conditioner. ⇒ "Guided fault-finding" function of vehicle diag‐
nostic, testing and information system VAS 5051.
