Why My Car Heat Blowing Cold Air

If your car’s heater is blowing cold air there are a few possible reasons why. One possibility is that the heater core is not getting hot enough. The heater core is what actually heats the air that comes into the cabin of your car and if it’s not getting hot then the air will be cold. Another possibility is that there is a problem with the blend door. The blend door is what directs the air from the heater core to the vents inside the cabin of your car. If it’s not working properly then the air will not be directed to the vents and will instead just stay in the heater core resulting in cold air.

One other possibility is that there is a leak in the heating system. If there is a leak then the coolant that is supposed to be flowing through the system and into the heater core is instead leaking out. This can happen if there is a hole in one of the hoses or a component of the system is not properly sealed. If there is a leak it needs to be fixed as soon as possible otherwise the problem will only get worse.

A final possibility is that the thermostat is not working properly. The thermostat is what controls the amount of coolant that flows through the system. If it’s not working properly then the coolant won’t flow properly and the heater core won’t get hot enough. This can be a problem even if there is no leak in the system.
