alright well now its winter and its very cold out in mass and my heat doesnt get very hot at all ill let my car warm up and get to operating temp right below half on the gauge and the heat wont be very hot at all if my windows cracked even the littlest bit my car feels like the heats not even on, it does blow out heat but just not as hot as i want or where i believe it should be... thinking it might be a heater core? maybe a leak somewhere? im lost so if someone could help that would be amazing! thanks
