When you turn on your car heater in the winter, it’s likely that you’ll feel the hot air blasting out quickly and intensely. But what about the cold air that comes out afterwards?
What Causes a Car Heater to Blow Cold Air?
If you are experiencing a car heater that is blowing cold air, there are a few things that you can do to troubleshoot the issue.
First, it is important to determine if the fan is working properly. If the fan is not working, then the problem may be with the motor or wiring. If the fan is working, but the car heater is still blowing cold air, it may be because of a blown fuse or a blockage in the line. In this case, it may be necessary to replace the car heater.
How to Fix a Blown Car Heater
If you are experiencing a cold air blowing out of your car heater, there is a good chance that it is blown. Blown car heaters are one of the most common problems that motorists experience and they are usually easy to fix. In this article, we will discuss the causes and solutions for a blown car heater.
The most common reason why a car heater will blow cold air is because of a clogged or faulty fan. If the fan isn’t spinning fast enough, warm air can’t escape from the heater and it will blow cold air instead.
To fix a blown car heater, you will need to take apart the unit and clean out any debris that may be blocking the fan. Once the fan is spinning freely, replace the belt if necessary and reattach everything back together. Finally, check for any loose wiring or other issues that may be causing the problem.
What to do if the Cooling System is Frozen
Your car’s cooling system is essential to keeping your engine running smoothly. In the event that the cooling system is frozen, it can cause some serious problems.
Here are four steps you can take in order to troubleshoot and fix the issue:
1. Check Your Thermostat: If your car’s thermostat is working properly, it should be setting the temperature at which your cooling system works best. If the temperature is set too low, the ice will form on the radiator and fan and will not disperse enough heat. If the temperature is set too high, the ice will melt and create a mess on your car’s engine and AC unit.
2. Clear Out The Cooling System: You’ll need to remove any debris that may be obstructing the flow of coolant through your system. This includes leaves, twigs, snow, and anything else that may have collected in your radiator or AC unit over time. Make sure all connections are clean before re-installing anything.
3. Drain And Replace The Radiator: If water isn’t flowing through your radiator due to obstruction, then it may be time to replace it.
Conclusion
If your car heater is blowing cold air, there are a few things you can do to troubleshoot the issue. First, check for obvious problems like an open or defective HVAC vent. If that doesn’t fix the problem, try turning up the car’s thermostat by 1-2 degrees and see if that makes a difference. Finally, if all else fails and you still have freezing temperatures in your car, it might be time to call a mechanic to take a look.
