ISSUE
Some 2011-2013 Fiesta vehicles may exhibit a lack of heat that results from a frozen blower motor. This may be caused by snow entering through the cowl top area. The snow melts and the water enters the blower motor and refreezes during a below freezing overnight soak. The blower motor fuse at location F4 in the Power Distribution Box may also be open.

ACTION
Follow the Service Procedure steps to correct the concern.
