Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
HVAC Module
The HVAC module contains the heated seat or heated/ventilated seat control buttons. If equipped with heated seats, 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.
