Code B272E Ford Description
If either the blower voltage supply or return circuits are open (to both cushion or backrest blowers) or shorted to voltage, the Diagnostic Trouble Code (DTC) is set and after 4-6 seconds the SCME disables outputs to the driver seat. The DTC also sets if the blower voltage supply or return circuit is open to only one blower when SCME supply voltage is less than 12 volts.

- Faulty Driver Cushion or Backrest Blower Motor
- Driver Cushion or Backrest Blower Motor harness is open or shorted
- Driver Cushion or Backrest Blower Motor circuit poor electrical connection
- Faulty Seat Control Module E (SCME)
