SUBJECT:
Model 171.454/456/458/473, Equipped with Airscarf (SA Code 403)
Fan Blade Deflection Noises when Airscarf in Use
If you receive customer reports in the above model vehicles that there are fan blade deflection noises coming from the seat backrest when the Airscarf is
in use in an occupied seat, this may be caused by the Airscarf blower fan housing flexing enough to where the fan blades strike the housing. As of
October 2008, the Airscarf blower motor housing was modified to be more robust. To remedy the issue, replace the Airscarf blower motor (Figure 1) on
both seats as per WIS document AR91.30-P-2000V.
Note:
Ensure that the blower motor replacement part has a production date of at least 08T288 (October 14, 2008).
