Climate Controlled Seat Operation

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

The driver and passenger climate controlled seat buttons are selected from the FCIM and FDIM (touchscreen). The climate controlled seat system functions independently of the vehicle's climate control system.

The seat cushion and backrest are each equipped with a blower motor assembly. As cabin air is drawn through each blower motor, the blower motors heat or cool the air, which is then directed into the foam pad where it is distributed along the surface of the cushion and backrest of the seat. Once the system is activated, the SCME uses a set of flexible algorithms to control the heating/cooling modes and the blower speed dependent on the commanded climate controlled seat settings.

The 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 an integrated filter attached to the blower motor housing. Heated or cooled air exits the blower motor and flows through the foam pad.
