HVAC Module

WARNING: This page is about a different car, the 2017 Ford Police Interceptor Utility and 2017 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

The HVAC module receives heated seat requests from the FCIMB (Front Controls Interface Module "B") and FDIM.

When the heated seats are activated, the HVAC module monitors the seat cushion temperature sensor and supplies heater current to the seat cushion and backrest heater mats until the desired setpoint temperature is reached. Once the setpoint temperature is reached, the HVAC module cycles the heater circuits on/off as required to maintain the setpoint temperature.
