  1. Broken Thermostat
  2. Broken Thermostat

    You may notice the thermostat gauge staying on the “C,” even after the engine has had enough time to warm up. If that’s the case, then the thermostat may be broken.

    When the thermostat isn’t working correctly, it can’t signal to the car that the engine is warm. As a result, coolant won’t be sent over to provide heat to the heater core, leaving you with cold air in the cabin.

  3. Issues with the Heater Core
  4. The heater core is a cooling system part that’s like a compact radiator. It’s made up of brass or aluminum tubing that carries coolant in and out. Plus, it’s responsible for the defrosting and heating actions inside your Honda.

    If coolant isn’t traveling through the heater core, but the coolant level is fine, then there may be an issue with the heater core itself. There are several ways to determine a problem with the heater core, including:

    • Overheating engine
    • A fruity, sweet smell in the cabin
    • Fog inside of the automobile

  5. Not Enough Coolant
  6. Engine Coolant Change

    On the other hand, your car heater may be blowing cold air due to not having enough coolant. Coolant is made up of half antifreeze and half water, and it’s used to cool the engine down-especially in the summer.

    When you put the heat on in the winter, coolant is brought over from the engine to the heater core to blow warm air into the vehicle. It may take a minute or two to switch from cool to warm air when you first turn your car on. However, if cool air continues to blow out, then you should check the coolant level to see if it’s high enough.

  7. Water Leaking
  8. Another reason why cold air could be coming out of the heater is from a water leak. There are various parts that could be leaking, such as the:

    • Radiator
    • Hoses
    • Water pump

    You’ll want to check these parts for damage. If any of them are leaking, then the car heater can’t operate properly.
