To an American what is this "heater matrix" you're talking about...just curious about the "lingo".
lol! Ok...We call that a "heater core"....we, as americans, took the blue pill...just sayin.For the heater to blow hot air there is a little radiator (just like the one at the front of your car just alot smaller) inside the heater box and when you turn the blower on it blows through it and warms the air up that's it really. Oh and no there is no keanu reeves haha
