If your car heater is blowing out cold air, chances are something is wrong. Much like a home heating system, it contains many components working together to make it work properly. If one of the components fails, the whole system will fail.
Before you can find out what needs to be fixed, you first need to find out what is causing it in the first place.
What is causing my car heater to blow out cold air?
- Not Enough Coolant: Your car uses coolant/ anti-freeze to cool your engine down during summer, during winter the coolant helps to cool down your engine heat through your heater core that then blows hot air into your car. If your heater is blowing cold air you should first check your coolant level.
- Faulty Heater Core: Your heater core is an important part of your car heating system. It is made up of tubes and fans that help to disperse heat into your car. Sometimes they malfunction and need to be repaired or replaced. If you have fog inside your car, can smell a sweet odor coming from your heater, your engine is overheating, or your coolant is been used quicker than normal you should get your heater core checked out ASAP.
- Broken Heater Controls:
Another common cause of your heater blowing cold air is if your heater control buttons are not working properly, which can happen over time from normal wear and tear. There could also be a problem with your heater control valve which can be found in your engine bay, the valve acts as a switch that controls your heating system. Your mechanic will be able to check this out for you.
