Review the complete repair procedure before starting.
(supplementary to REP 64 11 212)






1. When installing the heating / air conditioning fan it must not be installed so that there is a gap between the fan and the air conditioning unit, as shown in the picture.






2. This gap will cause the bracket to be damaged when the mounting screws are tightened (see 1).






3. When installing the heating / air conditioning fan, particular attention must be taken to ensure that the fan housing is not tilted and is flush against the air conditioning unit; no gap must be present (see picture).
