– Screw out the bolts -A- for the control motor to be removed.
– Mark the control motors (e.g. „B" and „C" on account of the
different position of the motor shaft).
– Take the corresponding control motor out of the holder -F-.
– Mark the cam plate -D- e.g. with „D" (to the rear left vent control
motor -V218- ) and -E- e.g. with „E" (to the rear right vent con‐
trol motor -V219- ) on account of possible interchange (as‐
signment ⇒ page 183
– Use 2 screwdrivers for example to carefully prise the cam plate
-D- or -E- off the corresponding control motor.
Installing
Install in reverse order, paying attention to the following.
– Attach the control motors -B- and -C- to the holder -F-.
– Attach the cam plates -D- and -E- to the shaft of the corre‐
sponding control motor (pay attention to correct assignment
⇒ page 183 ).
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.
