Code B2964 Ford Description

Upon receiving a signal from the Heating, Ventilation, and Air Conditioning (HVAC) Module, the Heated Seat Module will decrease one setting (the sequence is high, low, off, high, etc.). Circuits between the heated seat module and HVAC module supply the control signals for the indicators to operate. When a heated seat is set to high, both LED indicators above the heated seat control button will illuminate. When a heated seat is set to low, only the left LED indicator will illuminate. When a heated seat is set to off, neither LED will be illuminated. If a short to voltage condition is present on both heated seat indicator status circuits at the same time, the Diagnostic Trouble Code (DTC) will set.
