Keeping this in view, why is my car blowing cold air when the heat is on?Hot coolant from the engine passes through a heater core, which looks and functions a lot like a small radiator, and a blower motor forces air through it. It’s also the reason that a plugged heater core, stuck thermostat, or air in the cooling system can all cause a car’s heater to blow cold.Also Know, why is my car overheating and my heat not working? The heater not working in some cases may be related to the overheating problem you are also having. This may be due to a faulty heater blower motor or potentially a bad heater core. Engine overheating can be caused by a number of things such as low coolant levels, a faulty thermostat, or a failing coolant fan switch. Additionally, how can I test my car for no heat? First, check your coolant level to be sure there is enough liquid in there to even get to your heater core. If your radiator is very low on coolant, you’ll get no heat. If your levels are okay, you either have a bad water pump or a thermostat that isn’t opening.What causes no heat in your car?Another likely cause of a car that runs OK, but has no heat is a stuck thermostat. A vehicle thermostat regulates the coolant temperature in the engine. If it always stays near the cold side, the engine is not warming up properly. Likely due to a stuck thermostat.
