Code B272A Ford Description

The Seat Control Module E (SCME) monitors seat cushion temperature while it supplies voltage and ground to both blower motors. The SCME also supplies a variable voltage signal to control the blower speed. Cabin air enters the blower through a filter integrated to the blower motor housing. Heated or cooled air exits the blower motor and flows through a duct to the foam pad.
If the passenger seat cushion blower motor temperature exceeds 70 Â° C (158 Â° F) in cool mode or 85 Â° C (185 Â° F) in heat mode for more than 4 seconds the SCME shuts down the passenger seat system and sets this Diagnostic Trouble Code (DTC).
