Is the seat ventilation system connected to the air conditioning system?

Seat ventilation uses the air conditioning system. Seat ventilation is a summer cooling device for car seat air conditioning. Although automatic air conditioning can maintain a constant temperature inside the car during summer, the close contact between the passenger's body and the seat restricts airflow in the contact areas, making it difficult to dissipate sweat and causing discomfort. The seat ventilation system features a unique air circulation system that continuously delivers fresh air through small holes in the seat cushion and backrest. This prevents sweat buildup on the hips and back, providing a comfortable riding environment and effectively improving airflow between the body and the seat surface. Even during long rides, the contact areas remain dry and comfortable. The seat ventilation system integrates a total of nine axial-flow fans within the high-quality foam padding of the seat: four in the backrest and five in the seat cushion. These fans draw fresh cabin air into the seat and distribute it evenly across the entire seat surface through a breathable intermediate layer. Special perforations in the upholstery allow air to pass through the leather, minimizing sweat accumulation. Depending on the vehicle model, the three-speed fan can be controlled either via the center console or a dedicated control on the seat itself. The highest fan speed can quickly cool seats heated by direct sunlight, ensuring comfort even during summer.
Last time I went for car repair, the technician mentioned that seat ventilation is actually a separate system from the air conditioning. Seat ventilation primarily relies on small fans inside the seat. These fans draw air from beneath the seat cushion and blow it out through the ventilation holes on the seat surface. The fan system is independently installed within the seat frame and is completely disconnected from the air conditioning system's refrigerant lines. Of course, if you turn on the seat ventilation while the air conditioning is blowing cold air, the cool air inside the car will be drawn in by the fans, making the seat feel even cooler. Some high-end models may use software to coordinate the two systems, but fundamentally, they operate independently. If the seat ventilation stops working, it's most likely due to issues with the fan motor or wiring, and has nothing to do with the air conditioning compressor.
