– Check the levers of both control motors -A- and -B-, retaining
plate can only be installed correctly when they are located in
the position depicted (service position).
Note
Item -E- shows the respective adjustment range of the control
♦
motors.
If both control motor levers are not located in the position de‐
♦
picted, the control motor(s) may be connected via a 5A fuse
to a 12 V battery, for example, using an adapter lead (refer to
⇒ "9.11 Preparing Adapter Cables for Control Motor Actua‐
tion", page 117 ) (or an adapter lead from Connector Test Set
- VAG1594/C- to terminals "5" and "6"). Rotate control motor
for only as long until it has reached the position depicted (the
turning direction can be reversed by switching positive and
negative).
– Check position of threaded plates above which the retaining
plate is bolted on.
Note
The bolts -F- are used as a guide when installing retaining plate,
if they are screwed in too far, the retaining plate cannot be instal‐
led, if they are not screwed in far enough, it may possibly cause
noise.
– Connect the connectors to control motors (note the assign‐
ment, risk of interchange).
– Insert the retaining plate on to bolts -F-, when doing this make
sure that studs on levers of control motors -A- and -B- are gui‐
ded into lever guides on doors -C- and -D-.
– Slide the retaining plate -B- with control motors on to the A/C
unit from below.
– Check position of bolts -C- and their fit in retaining plate guides
(if retaining plate fits too loosely on bolts -C-, screw them in if
necessary far enough that there is no longer any play--do not
tighten).
– Check the routing of electrical wire and make sure while in‐
stalling that the wires do not come into contact with moving
parts of the control motors and door levers.
– Install the bolts -A-.
– Install retaining plate with control motors -V158- ( -V159- ) and
-V109- ( -V108- ). Refer to
⇒ "9.23 Retaining Plate with Control Motors V158 ( V159 ) and
V109 ( V108 ), Removing and Installing", page 153

necessary. Use the Vehicle Diagnostic Tester via the "Guided
Fault Finding" function.
