-
Check 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:
-
Position - E - shows the respective adjustment range of the control motors.
-
If both control motor levers are not located in the position depicted, the control motor (s) may be connected via a 5 A fuse to a 12 V battery
e.g. using an adapter lead (or an adapter lead from Connector Test Set VAG1594C 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 swapping Plus and Minus).
-
Check position of threaded plates - G -.
NOTE: Bolts - F - are used as a guide when installing retaining plate, if they are screwed in too far, the retaining plate cannot be installed, if they
are not screwed in far enough, it may possibly cause noise.
-
Connect connectors to control motors (note the assignment, risk of interchange).
-
Insert retaining plate on to bolts - F -, when doing this make sure that studs on levers of control motors - A - and - B - are guided into lever guides
on flaps - C - and - D -.

Slide retaining plate - B - with control motors on to heating 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 routing of electrical wire and make sure while installing that the wires do not come into contact with moving parts of the control motors and
flap levers.

Install bolts - A -.
-
Install the remaining removed components again in reverse order.
