Some 2011-2017 Fiesta vehicles may exhibit a lack of heat resulting from a frozen blower motor. This may be caused by snow entering through the cowl panel grille and prior screen assemblies. Snow may melt in the heating, ventilation and air conditioning (HVAC) case allowing water to enter the blower motor and freeze during a below freezing overnight soak. The blower motor fuse at location F4 in the power distribution box may also be open and the cabin air filter may be water saturated. Follow the Service Procedure steps to correct the condition.
