Consider these problematic areas for heating and cooling systems: • The heating system of a car is run by a small part called a heater core. This small device, much like an old-fashioned radiator, creates heat for the passenger cabin during cold weather by diverting heated radiator fluid through the heater core.
A heater can stop working for a number of reasons, including: A low antifreeze/water level in the radiator due to a leak in the cooling system. A bad thermostat that isn’t allowing the engine to properly warm up. A blower fan that isn’t working properly.

Why is my car blowing cold air when the heat is on?
Low Coolant Level
The coolant (usually a mixture of water and antifreeze) in your engine doesn’t just work to keep the engine from overheating: It’s also the source of heat supporting the heating system. If there isn’t enough coolant in your system, the heater core will blow cold air into your car.
Why is my heater not blowing hot air in my car?
Faulty heater cores and low or contaminated coolant levels often come hand in hand, and both issues may lead to your engine overheating and your heater not blowing hot air.
Is there a fuse for the heater in my car?

How expensive is it to replace a heater core?
The total cost of parts and labor will range between $800 and $1,000 to have your heater core fixed by a professional. Labor costs vary, so call ahead and get a quote from multiple repair shops. If you fix the heater yourself, you’ll only have to pay for the cost of a new heater core which runs between $100 and $300.
Thermostat. A faulty thermostat could be behind your car’s heater not working. If it isn’t opening up to let the coolant flow through it, the core can’t produce heat. Thermostats can also get stuck open causing the engine’s temperature to stay low.
Why is my heat not getting hot?
Low coolant: Whether caused by a leak or water evaporation, low coolant is the most common source of poor heater output. Thermostat: A stuck-open thermostat prevents the engine (and coolant) from heating up. Heater core: A clogged heater core restricts coolant flow, giving up little or no heat.
