"This was a design defect from day one. They reused the thermoelectric cooling units from the F150 and Fusion. But they failed to understand the basic thermodynamics of thermoelectric cooling. The heat has to go somewhere. In the F150 and Fusion, the underseat AC ducts cooled the thermoelectric cooling units so that they, in turn, can deliver cool air through the seat. Mustang had no underseat ac for the rear passengers. Thus the front seat thermoelectric cooling units could not reject heat. They actually heat the seats when set to cool unless you are winter driving with heat off or low."
