B19A4 LINCOLN Description
The Front Seat Climate Control Module (SCME) supplies voltage and ground to the driver seat backrest blower motor. The Front Seat Climate Control Module (SCME) also sends a speed control voltage signal to the blower motor to control blower speed. If the driver seat backrest blower speed circuit is shorted to voltage, the Front Seat Climate Control Module (SCME) shuts down the driver seat system and sets this Diagnostic Trouble Code (DTC).
