How to Switch Between Seat Ventilation and Heating in the Passat?
1 Answers
The seat ventilation function button for the Volkswagen Passat is located in the center of the dashboard. Press it to activate the ventilation mode, and you can also adjust the seat temperature. Seat Heating Working Principle: The seat is embedded with resistive heating wires, which are stitched inside the seat cover. By supplying electricity to these heating wires, the seat gradually warms up in a short time. A temperature sensor installed in the heating pad monitors the seat temperature, controlling the power supply to the heating wires to maintain the seat temperature within a suitable range. Seat Ventilation Working Principle: The seat cushion and backrest each have a ventilation system. Fans draw in air and direct it into a ventilation layer. Airflow then permeates upward through perforations on the seat surface. To accommodate the fans, the internal structure of the seat must be modified. Factors such as fan noise, vibration, airflow volume, and cooling speed must also be considered. The foam and upholstery of the ventilated seat require a special design to meet ventilation needs.
