Summary
This article supersedes TSB 18-2024 to update the vehicles affected.
Issue: Some 2011-2018 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 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. Blower motor fuse F4 in the battery junction box (BJB) may also be open and the cabin air filter may be saturated.
Action: Follow the Service Procedure steps to correct the condition. Parts
