If your car’s heater is blowing cold air there are a few potential reasons why. The most common reason has to do with the coolant level in your car. If the coolant level is low it won’t be able to properly heat up the engine and as a result the heater will blow cold air.
There are a few ways to check the coolant level in your car. The first is to simply look at the coolant reservoir under the hood. If the level is below the “full” line then you’ll need to add more coolant. The second way to check is to actually start the car and let it warm up for a few minutes. Then feel the radiator hoses. If they’re not hot that means the coolant isn’t flowing properly and needs to be topped off.
Another potential reason why your heater is blowing cold air is that the blower motor is not working properly. The blower motor is responsible for circulating the air through the heater core. If it’s not working then the air will not be heated.
To check if the blower motor is working you can simply turn on the heater and see if the fan is blowing. If not then it’s likely the blower motor is to blame.
Lastly it’s possible that there is an issue with the heater core itself. The heater core is what actually heats up the air before it’s sent through the vents. If there is a leak in the heater core coolant can escape and the air will not be heated properly.
If you suspect that the heater core is the problem the best way to confirm it is to take the car to a mechanic and have them take a look.
In conclusion if your car’s heater is blowing cold air the most likely culprit is a low coolant level an issue with the blower motor or a problem with the heater core.
Why is my heater blowing cold air in my car?
Answer 1: There are a few reasons this could be happening.
The first is that your engine isn’t hot enough.
If your engine isn’t hot enough the heater can’t blow hot air.
The second reason is that your heater core could be blocked.
If your heater core is blocked the heat can’t get through to the inside of your car.
The third reason is that your car might not have enough coolant.
If your car doesn’t have enough coolant the heat can’t circulate properly and will get trapped in the engine.
