5 Reasons Your Car’s Heater is Blowing Cold Air
Living an active lifestyle means sticking to a schedule that accommodates everything needed for you and your family to achieve your goals. A dependable vehicle is a key part of that equation, and when the temperature drops, you want the assurance that your car, and its heater, are functioning properly.
How A Car Heater Works
The moment you start your car, the engine begins to heat up and continues getting hotter as you drive. Some of the excess heat is lost through the exhaust system but the remainder is managed by the engine coolant. Once the vehicle has reached its normal operating temperature, the coolant circulates through the engine and transfers the heat to the radiator and heater core. A fan controlled by the passengers in the vehicle blows the heat from the heater core into the vehicle cabin.
Why Your Car Heater is Blowing Cold Air
It can be frustrating on a cold, winter day to turn on the heat in your car and have nothing but cold air blowing from the vents. There are several components in your vehicle’s engine that work together to provide your interior heat, and one or more issues could be happening.
- If you don’t have enough engine coolant, it won’t be able to carry sufficient heat to your heater core to provide warm air. Have your air coolant levels checked. This could solve the issue immediately.
- The heater core could be malfunctioning. This component is responsible for all heating actions in your vehicle, including defrosting. Have your car’s heater core checked by a technician as soon as issues arise.
- The buttons and switches in your vehicle used to control the heat and fans are not exempt from wear and tear. After years of use they can break or get gummed up. You may need to have them replaced.
- Once your engine warms up, the thermostat should reflect this. If it stays in the “cold” zone due to a broken thermostat, it cannot signal the vehicle that the engine is warm. The coolant will fail to transfer heat to the heater core. Having a new thermostat installed solves this right away.
- Water leaks from any point in your engine will affect your vehicle’s heater. Leaks can happen in the hoses, radiator, and water pump. These parts need to be checked by a professional to prevent engine damage and to ensure you have interior heat.
