– Before fitting the cover -A-, check for damage to the sealing
lip -B- on the version with 4 attachment points.
– Check proper fitting of the socket -C- and the routing of the
wiring to the control motor as shown.
– Also fill the open groove of the socket -C- with exactly the
amount of adhesive sealant (e.g. silicone adhesive sealant -D
176 001 A3- ) required to reliably seal the connection with the
cover.
Note
As of 12.2003, a modified cover for the control motor (with 4 in‐
stead of 2 attachment points), a suitably adapted cover with air
recirculation flap -E- and a wiring harness with a modified socket
-D- were gradually introduced ⇒ Electronic parts catalogue . The
connection between the air conditioning unit, the cover and the
socket is however still to be additionally sealed with adhesive
sealant on this version as well.
– Fit the cover -B- (this illustration shows the version with 2 at‐
tachment points).
– Check the connection between the air conditioning unit and
the cover -B- (reliable sealing is only provided if adhesive
sealant emerges all round).
– The location at which the wiring harness enters the socket
-C- (refer to Fig. above) is also to be sealed with adhesive
sealant (e.g. silicone adhesive sealant -D 176 001 A3- ).
– Remove the adhesive sealant emerging at the connections to
the air conditioning unit on screwing on the cover -B-.
– 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,

ment, additionally check the air recirculation flap (must close
completely).
