TECHNICAL SERVICE BULLETIN
Lack Of Heat - Blower Motor Frozen - Cold Weather Conditions
25 January
2018
This bulletin supersedes 16-0018. Reason for update: Concern Carryover to New Model
Model:
Ford
2011-2017 Fiesta
Summary
This article supersedes TSB 16-0018 to update the model years.
Issue: 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.
Action: Follow the Service Procedure steps to correct the condition.
