The main function of the air parking heater in the car is to provide the required heat for the cockpit and melt the ice, snow or frost on the car windows.
Here are some tips for detecting whether the heater is malfunctioning:
1. The defrosting heater in the car has several vents on the windows, and the heated air is sent to the car through the vents. Turn on the heater and face the vent with your hand. If you can feel the air and it is hot, then your heater is working properly.
2.Turn off the radio or other devices, park the car in a quiet place and listen to the sound of your heater fan turning. If you do not hear the sound of the fan rotating or the air moving, it means that your fan is broken, and the heater may be broken. If you can feel the hot air from the vent, but the hot air is not blowing out, it means that the motor of your heater is broken.
3. If you can feel the air moving or hear the fan turning, it means your heater fan is good. However, if the air is not hot, your heater may be broken even if the fan is working, in which case you need to replace your heater.
4. If you can't hear the fan rotating or can't feel the air flow without any heat, it means that the entire defrost heater may be broken. You need to check the fuse box and replace any blown fuses.
