Many modern vehicles are equipped with seats that can be heated to give you more comfort in certain weather conditions.
Seat heater switch operationThe seat heater switch allows you to turn on the seat's heating, which has electricity traveling to the coil through a circuit. Once it is engaged a small electrical charge flips the relay switch and lets electricity travel from the battery. The seat heater switch can be found mounted in different places based on the make and model of the vehicle. The switch is necessary to activate the seat heating when it is cold so that you can have a more comfortable ride. Without the switch, it would be difficult to have the heated seating function correctly.
