Unless you have a 2017, the seats don’t cool, they just use a fan to ventilate. In 2017 they had a thermoelectric cooler. After that it’s just a fan that pushes the cabin air through the seat.This is my first “winter” with mine and I’ve noticed the steering wheel is warm but the seat seems normal. Maybe it is warm. It never seems like my seat is cool in summer unless I leave it for a while, which could be the a/c hitting it or it’s just too hot in Florida for it to work quickly. Having the lights on must be a newer model thing.
