I swear I read a post about this but can’t seem to find it — I’ve had my MY for a month now and have consistently noticed the heat in for the lower vents is nowhere as warm as the upper vents. Feels like cooler air blowing on my legs. It doesn’t seem like it’s purely cold air, just colder air. Enough to be uncomfortable. Is this normal? Or may I have a heat sensor issue on the verge?
